摘要:

【目的】研究15个葡萄砧木品种新梢的生长及叶片叶绿素荧光参数对高温的响应,评价其耐热性的差异性,筛选出耐热性较强的砧木,为砧木的耐热性选择提供理论依据。【方法】在吐鲁番自然高温条件下,研究15个葡萄砧木品种在田间高温下的生长情况并测定叶片的荧光参数,利用隶属函数法分析评价其耐热性。【结果】在40℃高温气候条件下,110R和Fercal叶片卷曲,山河2号轻微卷曲,其它砧木均无卷曲,叶缘正常,叶片上无斑点;植株生长前期速率随温度升高而下降,后期生长速率平稳。15个砧木品种的耐热性分为6类。【结论】砧木山河2号的耐热性最强,140R最弱。

Abstract:

【Objective】 To study the growth of 15 grape stock varieties and the response of leaf chlorophyll fluorescence parameters to high temperature and evaluate the differential of heat resistance by selecting stocks with strong heat resistance in the hope of providing a theoretical basis for grape grafting cultivation. 【Methods】 15 grape rootstocks were used as experimental material,growth and chlorophyll fluorescence parameters were measured under natural high temperature,and the heat resistance was evaluated by membership function method. 【Results】 Leaves of 110R and Fercal were curled,leaves of Shanhe 2 was slightly curled,others were smooth,leaf margin was normal,no spot was found on leaves.Growth rate was decreased with temperature increasing,and at later stage, growth rate tended to be stable.Chlorophyll fluorescence parameters were measured when temperature was stable above 40℃ and order sample optimal segmentation clustering method was used to analyzed chlorophyll fluorescence parameters of grape rootstock,15 rootstocks were divided into 6 categories. 【Conclusion】 Rootstock Shanhe 2 has the strongest heat resistance and 140R is the weakest.

Key words: grape rootstock; chlorophyll fluorescence; heat tolerance
