Abstract:[Objective] To investigate the effects of different light qualities on the growth, photosynthesis, flavonol accumulation and antioxidant capacity of Ginkgo biloba, and to screen out the more suitable light qualities for the growth and flavonol accumulation of Ginkgo biloba, so as to provide theoretical basis for the improvement of Ginkgo biloba"s medicinal value. [Methods] Two-year-old Ginkgo biloba seedlings were used as test materials, and four light quality treatments with red and blue ratios of 1 : 1 ( 1R1B ), 1 : 3 ( 1R3B ), 1 : 5 ( 1R5B ) and white light ( W, control ) were set up. After 20 days of treatment, the growth, photosynthetic physiology, flavonol content and antioxidant capacity of Ginkgo biloba were analyzed. [Results] Different ratios of red and blue light reduced Ginkgo biloba biomass and were detrimental to plant height and ground diameter compared to white light. 1R5B treatment could promote the increase of leaf area, total chlorophyll content and Ci. The Tr and Gs of leaves and the total biomass of Ginkgo biloba were increased by 1R1B treatment. The contents of Pn, Fm, Fv / Fm, Fv / Fo, qP, carotenoids, total flavonols and antioxidant capacity of leaves under 1R3B treatment were the highest. [Conclusion] Different proportions of red and blue light had an effect on the growth and photosynthetic characteristics of Ginkgo biloba, and significantly increased the content of flavonols and antioxidant capacity. Comprehensive analysis showed that 1R3B treatment was most conducive to the accumulation of flavonoids in Ginkgo biloba, which was the ideal light quality.

Abstract:[Objective] The study aims to explore the growth and physiological response characteristics of Canavalia maritima seedlings under water stress, and provide a reference for water management during the seedling stage and for the cultivation of high-quality plants in coastal sandy lands.[Methods] One-year-old C. maritima seedlings were subjected to simulated drought (soil relative water content at 20%, 40%, and 60%), suitable water content (80%, control), and waterlogging (100%) through a pot water control experiment. Their growth and physiological indices were analyzed. [Results] Under both drought and waterlogging stress, leaf dry weight significantly decreased, while leaf relative water content significantly increased. Seedling height and leaf area significantly increased under waterlogging but significantly decreased under severe drought. Total root length, total root surface area, total root volume, and mean root diameter increased under drought and decreased under waterlogging. The content of malondialdehyde and the activities of catalase (CAT) and peroxidase (POD) significantly increased, while the activity of superoxide dismutase (SOD) remained relatively stable. Soluble protein content decreased, whereas soluble sugar and proline contents significantly increased. The chlorophyll content significantly decreased under severe drought. Initial fluorescence significantly increased, while maximum fluorescence , maximum photochemical efficiency, and maximum quantum yield significantly decreased.[Conclusion] Under drought and waterlogging stress, C. maritima seedlings demonstrated strong tolerance by altering water accumulation and distribution patterns, increasing the activities of CAT and POD, and enhancing soluble sugar and proline contents.

Abstract:[Objective] The purpose of this study was to investigate the mitigation effect and physiological mechanism of different concentrations of salicylic acid (SA) on high temperature stress injury of watermelon seedlings, and to provide a theoretical basis for the rational application of SA in watermelon cultivation and production. [Methods] Potted ‘K53’ watermelon seedlings in greenhouse were used as experimental materials. After spraying different concentrations (0,0.5,1.0,1.5,2.0 mmol/L) of SA on the leaves, the seedlings were stressed at 42°C for 36 h day and night. The growth characteristics, anatomical structure, physiological and biochemical indexes of watermelon seedlings were observed, and the mitigation effects of each treatment were comprehensively evaluated by membership function method. [Results] After high temperature stress, the leaves of watermelon seedlings wilted seriously, the growth of root length was inhibited, the leaves became thinner, and the mesophyll cell structure was damaged. After SA application, the leaves became thicker, photosynthetic pigment content, photosynthetic gas exchange parameters, antioxidant enzyme (POD, SOD, CAT) activity and osmotic adjustment substances (proline, soluble sugar, soluble protein) content increased significantly, MDA content and relative conductivity decreased significantly. Compared with the high temperature stress treatment group, the MDA content of leaves under 1.0 mmol/L SA treatment was significantly reduced by 33.70%, the relative conductivity was significantly reduced by 58.58%, the contents of chlorophyll a and chlorophyll b were significantly increased by 22.71% and 21.63%, respectively. The net photosynthetic rate was significantly increased by 98.34 %, and the activities of SOD and CAT were significantly increased by 23.98% and 19.71%, respectively. [Conclusion] Pre-spraying different concentrations of SA could alleviate the damage of watermelon seedlings under high temperature stress, and 1.0 mmol/L SA treatment had the best effect.

Abstract:【Objective】 To explore the changes in photosynthetic physiology and leaf structure of tea trees under different intercropping patterns. 【Methods】Four intercropping modes, namely, R delavayi-tea(MT), winter cherry-tea (DT), walnut-tea (HT), and pure tea plantation (CK), within the planting range of the Cherry Blossom Valley of Mount Wuliang in Nanjian County, Yunnan Province, were investigated through the study of leaf anatomy of tea trees and the changing law of the tea tree"s photosynthetic physiological and ecological functions under different intercropping modes. 【Results】The three intercropping modes significantly reduced the photosynthetically active radiation flux (PAR) and the temperature of tea tree leaves (TL) in the spring, and the net photosynthetic rate (Pn), and transpiration rate (Tr) of different intercropping modes in the spring and autumn roughly showed a single-peak curve with a rise followed by a decline, in which the CK mode differed significantly from the other intercropping modes, and the daily change of the intercellular carbon dioxide concentration (Ci) showed a U-shaped curve, with the first decline and then increase. The thickness of fenestrated tissue and leaf thickness of tea leaves in different intercropping modes in spring and autumn were significantly lower than that in CK mode; PAR was significantly positively correlated with TPT, P/S and CTR in spring and negatively correlated with CLR in autumn, and Pn was significantly positively correlated with CTR in autumn. 【Conclusion】Different intercropping modes effectively affected the photosynthetically active radiation flux, leaf temperature, net photosynthetic rate, transpiration rate, stomatal conductance, and intercellular carbon dioxide concentration of tea trees in tea plantations, among which the effects were more significant in the two intercropping modes of MT and DT. Tea trees grown under different intercropping modes will gradually change leaf morphology to adapt to different environmental characteristics; there is a certain correlation between the anatomical structure of tea tree leaves and photosynthetic physiology, and the thickness of palisade tissues, lower epidermal thickness, ratio of palisade to sponge tissue ,and the cell tense ratio can be used as an important index for determining the photosynthetic capacity of the leaves in a certain period of time and within a certain range.

The research lays the groundwork for investigation into the functions of the tea plant BRX genes. 【Methods】 Employed the tea plant genome database and bioinformatics software such as TBtools, we have conducted an identification and analysis of BRX genes. The experimental material was tea plant variety ‘Shuchazao’. Different treatments including salt stress, drought, high temperature, low temperature, and exogenous GA3 application have been applied to it for various durations. The relative transcript abundance of the BRX gene family across different tissues and under these stresses conditions was quantified using RT-qPCR. 【Results】 A total of 5 CsBRX genes have been identified, encoding proteins composed of 313~370 amino acids. The structures of genes were similar and highly conserved. The promoter regions contained hormone and stress response elements. Based on evolutionary relationships, BRX proteins were divided into 4 subfamilies. CsBRX1, CsBRX3 and CsBRX5 were all expressed in young leaves, while CsBRX4 was exclusively expressed in old leaves. Under salt stress for 12 h, the transcriptional levels of CsBRX1, CsBRX2 and CsBRX4 were elevated to the greatest extend. CsBRX2 exhibited a swift response to low-temperature stress, with its relative expression peaked at the 1 h mark. CsBRX2 demonstrated a positive response to exogenous GA3 signaling, and its expression reached a zenith at the 24 h interval. 【Conclusion】 The CsBRX genes demonstrated tissue-specific expression patterns, responded variably to multiple stresses and GA signal, which offered insights for the investigation of stress tolerance mechanisms within tea plants.

Abstract:【Objective】 ABA is a key hormone for drought stress in plants. Differential metabolites and their associated pathways of ABA-mediated dehydrated response in the isolated branches of Salix matsudana were revealed by metabolomics analysis, which provided the research basis and the theoretical basis for the response to drought stress in S. matsudana. 【Methods】The authors investigated the differential response of the xylem metabolomes of the S. matsudana branches dehydrated to the different water potentials after soaked in the sodium tungstate solution, an inhibitor of ABA synthesis, using the isolated branches of S. matsudana as materials. 【Results】 Compared with the deionized water-soaked non-dehydrated branches, the dehydrated to P50 water potential branches: The abscisic acid content was significantly increased by 4.25 times, and the content of the soluble sugars such as D-fructose was significantly increased along with the content of amino acids such as histidine. ABA synthesis inhibitor-soaked branches compared to deionized water-soaked branches: The content of abscisic acid was significantly reduced by 3.82 times, and the content of the soluble sugars such as D-1,5-defructose and amino acids such as phenylalanine was significantly reduced after soaked in the inhibitor of ABA synthesis. Plant hormone signal transduction, carotenoid biosynthesis and starch and sucrose metabolism pathways were the key pathways in the dehydrated response of S. matsudana branches. 【Conclusion】 In the S. matsudana branches after dehydration, the ABA content increased significantly, which mediated the starch hydrolysis process and other processes to reduce the osmotic potential of cells in response to the drought stress.

Abstract:Abstract [Objective] To compare the genetic diversity and relationships between the chloroplast genomes of olive varieties selected and bred in China and those in the Mediterranean olives, and to estimate the maternal diversity of olive varieties selected and bred in China, and in turn provide a basis for the development of Chinese olive accession. [Methods] NOVOPlasty v.4.3.1 was used to assemble chloroplast genomes, which were based on the genome re-sequencing data of the nine olive varieties selected and bred in China and seven Iranian accessions, both of which were sequenced in this study, and fifty-two Mediterranean olive accessions downloaded from the database, and then calculated the sequence polymorphism; GPA, RAxML-NG, and Network 5.0 and other software were used to construct the chloroplast genome map, the relationships of phylogeny and network of haplotype respectively. [Results] The chloroplast genomes of the analyzed olive accessions were consistent in terms of tetrad structure and number of genes in this study. All chloroplast genomes identified seventeen haplotypes, among which, the olive varieties selected and bred in China have only one haplotype which share with the most cultivated olives. The oleasters have the highest genetic diversity, followed by the cultivated olives and then Iranian accessions, while nine olive varieties selected and bred held all genetic diversity of 0. The phylogenetic relationship was consistent with the network of haplotype, one branch includes the most of the cultivated varieties, Iranian olive accessions and all olive varieties selected and bred in China. [Conclusion] The nine olive varieties selected and bred in China showed an extremely low diversity of maternal origin. It is necessary to select and breed the olive varieties adapted to China’s habitats from a more comprehensive lineage of olive accession in the later stages.

Abstract:【Objective】To investigate the response of C, N, P, and K distribution law in Xanthoceras sorbifolia seedlings to water and nitrogen addition, providing references for water-nitrogen environmental adaptation strategies and high-quality seedling cultivation.【Methods】A two-factor (nitrogen and water) randomized block design was adopted in this study. four N fertilization levels [N0: g/(m2·a), N1: 5 g/(m2·a),N2:10 g/(m2·a) and N3:15 g/(m2·a)] and three levels of water addition [ well watered (WCK), drought (Wd), and fully watered（Ww）] were set up to explore the impact on the ecological stoichiometric characteristics of Xanthoceras sorbifolia seedlings" leaves, branches, and roots.【Results】(1) The C, N, P, and K levels of seedlings were independently or interactively influenced by nitrogen and water, while the stoichiometric ratios were mainly affected by nitrogen addition. Under well-watered conditions (WCK), nitrogen addition increased C, N, and P levels. Under drought conditions (Wd), high nitrogen addition (N3) Ncould resist drought by increasing K level and decreasing N and P levels. Under well-watered conditions (Ww), only high nitrogen addition (N3) effectively alleviated nitrogen limitation. (2) C, N, P, and K nutrients were mainly concentrated in leaves, supporting photosynthesis and vegetative growth. The variability of N and P contents in leaves was high , but the N/P ratio remained stable.(3) The same element exhibited a high correlation between different organs, particularly between leaves and roots, contributing to the maintenance of stable growth.【Conclusion】Nitrogen addition can alleviate nitrogen deprivation whereas increases the demand for P and K. It is recommended to reduce nitrogen fertilizer application under suitable water conditions to reduce pollution and maintain growth potential.

The methods of trait network and principal component analysis were used to quantify the regional differentiation of traits, and to clarify the main climatic factors driving the variation of traits and their habitat adaptation strategies. 【Results】 (1) The average coefficient of variation of each trait was 12.09%-60.35%, and the variation level of photosynthetic physiology and stomatal related traits was generally higher than that of other traits. (2) The importance percentage of photosyntetically active radiation, growing season mean temperature, annual mean precipitation and aridity index on trait variation were 35.45%, 28.37%, 19.36% and 16.93%, respectively. Among them, photosyntetically active radiation in the growing season was the most important climatic factor driving trait variation. (3) The central trait of the trait network was the maximum net photosynthetic rate.【Conclusion】 There were differences in the adaptation strategies of P.alba in the precipitation gradient. From the humid/semi-humid region to the arid region, its carbon economy strategy changed from a relatively conservative type to an acquisition type.

Abstract:[Objective] In order to provide data support and theoretical guidance for grassland restoration and biodiversity protection, the effects of grazing suspension in spring on the niche of Carex tibetikobresia meadow plants were explored. [Methods] Taking different grazing time as the environmental gradient, the importance value, aboveground biomass, niche breadth and overlap value of different economic groups of typical Carex tibetikobresia meadow in three-river source region were analyzed by using single factor analysis of variance and r software package (Pheatmap). [Results] Grazing for 50 days increased the important value of Cyperaceae (15.09%) and decreased the important value of poisonous weeds (50.09%);The aboveground biomass of different economic groups (except poisonous weeds) was significantly increased by 50 days, which increased by 220.99%, 69.73% and 139.37% respectively; Carex tibetikobresia S. R. Zhang、Helictotrichon tibeticum(Roshev) Holub(0.999); There are 55 pairs with (NO) greater than 0.990, accounting for 26.10% of the total, and 3 pairs with NO less than 0.75, accounting for 1.43% of the total.[Conclusion]The grazing moratorium in spring affected the important values and aboveground biomass of different economic groups in Carex tibetikobresia meadow. From the niche point of view, grazing suspension in spring is beneficial to the growth of fine forage and can effectively promote grassland restoration.

Abstract:[Objective] Elucidating the tripping mechanism and the role and status of flower in this process,are of great significant to explor the diverse pollen dispersal mechanism [Methods] The studies were carried out based on the field observation of tripping phenomenon, pollinator visiting behavior, the control experiment of pollen transfer and the anatomical observation of flower structure in Medicago sativa L. cv. Xin Mu No.4. [Results] The specialization structure of wings and keel edge are nested with each other and form the touch sensitive flower structure of alfalfa. The “sensitiveness” structure not only has high selectivity to pollinators, but also can manipulate pollinators" visiting behavior by changing the location of honey hole before and after tripping. Once the keel flap is tripped, about 90% of the pollen in the anther was dispersed, the gynostemium will not return to the original position, and the flower would close on the same day, or it will continue to open 5-6 d, which is a one-time pollen release mechanism. Tripping efficiency of insects, being not related to the insect"s size, determines the tripping contribution rate together with its visiting frequency. The insect"s second visiting did not increase the removing of residual pollen from anthers and pollen deposition on stigma. [Conclusion]The special flower structure and its regulation to pollinators" foraging behavior promoted the occurrence of tripping phenomenon, and benefits maximizing of the male fitness in Medicago sativa L. cv. XinMu No.4.

Abstract:[Objective] The purpose of this study is to explore the pollination biology and reproductive characteristics of Rhododendron excellens, providing a theoretical basis for the conservation of small populations.[Methodd] This study observed the reproductive characteristics of R. excellens by investigating its floral characteristics, pollinator and its associated visiting characteristics, fragrance of flowers and breeding system. [Results] (1) Unlike widespread Rhododendron species, pollen vitality of R. excellens was lower whereas the stigma vitality is strong, with a longer duration. (2) The main pollinating insect was Apis cerana in the daytime. The main volatile was 1,8-cineole which could attract moths for pollinating R. excellens at night. (3)The breeding system test indicated that R. excellens can set fruit through self-pollination, but the fruit set rate of self-pollination is lower than that of cross-pollination. Artificial supplementary pollination treatment can greatly improve the fruit set rate compared to natural control, indicating that there is pollen limitation in the seed formation process of R. excellens.[Conclusion] The flower morphology of R. excellens tends to avoid autonomous self pollination,Simultaneously, low pollen viability but sustained strong stigma receptivity may be a strategy for plants to adapt to lower pollination efficiency. The main pollinating insect was A. cerana in the daytime. However, moth pollination that occurred at night can not be excluded. Its breeding system is self-compatible and is evolving towards a facultative mixed mating system.

Abstract:[Objective] Corydalis , a large genus of Papaveraceae, is considered one of the most challenging groups in taxonomy. The classification of Corydalis in Henan remains unclear due to insufficient exploration of taxonomic characteristics and a lack of thorough revisions. [Methods] After reviewing the original literature and specimens from the Chinese Virtual Herbarium (CVH),we conducted field investigations, took photos and collected specimens. [Results] We confirmed three newly recorded species of Corydalis species in Henan Province, namely C. nanwutaishanensis Z.Y. Su & Lidén, C. ochotensis Turcz. and C. wilfordii Regel. We also verified that C. shaanxiensis Lidén ex C. Y. Wu, H. Chuang & Z. Y. Su and C. micrantha (Steph.) Pers. were misidentified as C. curviflora Maxim. and C. humosa Migo. in previous literature. In addition, we found a translation error in the label of C. pseudoincisa C.Y.Wu, Z.Y.Su & Lidén, which might not occur in Henan. [Conclusion] This study can be used to provide data for the study of biodiversity science in Henan and the revision of Flora of Henan.
