    摘要:

    【目的】为探究北苍术叶片功能性状对科尔沁沙地的响应与适应规律。【方法】选择4个种源地北苍术半野生种子通过同质园实验育苗移栽于奈曼旗中(蒙)药材科研基地,以3年生北苍术叶片为研究材料,探究北苍术叶片结构与功能特性对科尔沁沙地的响应与适应规律。【结果】引自扎鲁特旗的北苍术下部叶叶裂程度较明显,叶片革质化;北苍术叶上表皮细胞厚度、下表皮细胞厚度变异系数与可塑性指数均较大,引自围场县北苍术叶片上表皮细胞厚度、扎鲁特旗北苍术叶片下表皮细胞厚度显著高于其他种源地,栅海比、组织结构紧密度较大;引自阿荣旗、扎鲁特旗种源地北苍术叶片上表皮气孔数量较多,喀喇沁旗上表皮气孔数量极少、气孔密度较小,喀喇沁旗种源地叶片下表皮气孔数量显著高于其他3个种源地;围场县、扎鲁特旗种源地北苍术叶片光合能力强。【结论】综合分析,引自围场县、扎鲁特旗种源地的北苍术对科尔沁沙地有较强的适应能力。

    Abstract:

    【Objective】 The study aims to explore the responsive and adapted routine of leaf functional traits of Atractylodes chinensis to Horqin sandland. 【Methods】 Through a homogeneous gardening experiment, selection of semi-wild Atractylodes chinensis (DC.) Koidz. seeds from four seed sources were transplanted to the Chinese (Mongolian) medicinal herb research base in Naiman Banner. The leaves of three-year-old A. chinensis were used as research materials. The purpose of this experiment was to examine how A. chinensis''s leaf structure and functional properties responded to and adapted to the sandy land of Horqin. 【Results】 The findings indicated that the degree of leaf cleavage in the lower portion of the A. chinensis introduced from Zhalute Banner was more evident;additionally, the thickness of the upper and lower epidermal cells of the leaves of the A. chinensis introduced from Weichang County and Zhalute Banner were found to have significantly higher coefficients of variation and plasticity indices than those of the other seed source sites; additionally, their fenestration sea ratios and the tightness of their tissues and structures were greater;The top layer of A. chinensis leaves from Arong Banner and Zhalute Banner sources had a greater number of stomata,whereas the upper layer of A. chinensis leaves from Harqin Banner had a very tiny number of stomata and a low stomatal density.A. chinensis leaves from the Zhalute Banner and Weichang County sources had a robust photosynthetic capacity,and the leaves from the Harqin Banner sources had a notably greater number of stomata in the lower epidermis than the leaves from the other three sources. 【Conclusion】 Comprehensive investigation revealed that A. chinensis from Weichang County and Zhalute Banner were highly adaptable to the Horqin Sandy soil.
