    摘要:

    【目的】探讨和田地区设施温室葡萄品种光合和叶绿素荧光日变化特征,综合评价其光合能力强弱,为该地区温室葡萄引种及栽培管理措施制定提供参考依据。【方法】以和田设施温室引入6个葡萄品种‘户太八号’‘妮娜女皇’‘夏黑’‘阳光玫瑰’‘新郁’‘克瑞森无核’为试验材料,测定并分析各品种光合有效辐射(PAR)、叶绿素相对含量(SPAD)、光合与叶绿素荧光参数,并利用主成分分析对各鲜食葡萄品种能力进行综合性评价。【结果】(1)设施温室光合有效辐射在不同位置总体表现出棚前>棚后>棚中,在不同架面位置总体表现为架上>架中>架下。(2)葡萄叶片SPAD值在不同架面位置表现为架上部>架中部>架下部,在品种间由高到低依次为‘克瑞森无核’‘夏黑’‘新郁’‘户太八号’‘阳光玫瑰’‘妮娜女皇’。(3)各品种Pn、Gs、Tr均呈现出双峰曲线的日变化趋势,Ci日变化总体呈现U形或W形变化规律;Fv/Fo与Fv/Fm总体上呈现出先下降后上升的日变化规律。(4)6个葡萄品种的光合能力表现为‘克瑞森无核’>‘夏黑’>‘阳光玫瑰’>‘新郁’>‘户太八号’>‘妮娜女皇’。【结论】 ‘克瑞森无核’与‘夏黑’相比其他品种有较高的Pn、Gs、Tr、 Fo、Fm和较低的Fv/Fo与Fv/Fm,对和田地区适应性较强,能够适应当地的高温与高光强设施环境。

    Abstract:

    [Objective] The diurnal variation characteristics of photosynthesis and chlorophyll fluorescence of greenhouse grape varieties in Hotan area were discussed, and their photosynthetic capacity was comprehensively evaluated, so as to provide reference for the introduction and cultivation management measures of greenhouse grapes in this area. [Methods] Six grape varieties ‘Hutai 8’‘Queen Nina’‘Summer Black’‘Sunshine Muscat’‘Xinyu’ and ‘Crimson Seedless’ were introduced into Hotan greenhouse as experimental materials. The photosynthetic active radiation (PAR), relative chlorophyll content (SPAD), photosynthesis and chlorophyll fluorescence parameters of each variety were measured and analyzed, and the principal component analysis was used to comprehensively evaluate the ability of each table grape variety. [Results] (1) The photosynthetically active radiation of greenhouse in different positions in general shows that before the shed>behind the shed>middle the shed, and the overall performance in different trellis in general shows that on the trellis>middle the trellis>under the trellis. (2) The SPAD values of grape leaves on different trellis was shown as on the trellis>middle the trellis>under the trellis, and the order from high to low among varieties was ‘Crimson Seedless’‘Summer Black’‘Xinyu’‘Hutai 8’‘Sunshine Muscat’‘Queen Nina’.(3) The diurnal variation of Pn、Gs and Tr of each variety showed a bimodal curve, and the diurnal variation of Ci showed a U-shaped and W-shaped variation.Fv/Fo and Fv/Fm generally showed a downward trend and then an upward trend. (4) The photosynthetic capacity of six grape varieties was ‘Crimson Seedless’>‘Summer Black’ >‘Sunshine Muscat’ >‘Xinyu’>‘Hutai 8’>‘Queen Nina’. [Conclusion] ‘Crimson Seedless’ and ‘Summer Black’ have higher Pn、Gs、Tr、Fo、Fm and lower Fv/Fo and Fv/Fm compared to other varieties, and are better adapted to the Hotan area, able to adapt to the local environment of high temperature and highlight intensity facilities.
