Abstract:

【Objective】 To explore the relationship between leaf anatomical structure indexes and drought resistance of grape rootstocks, and to provide a convenient and effective method for screening grape varieties with drought resistance.【Methods】 The perennial field vines of 17 grape rootstock varieties were treated with drought stress(21d), the relative moisture content and electrical conductivity of stem and leaf were measured, and the anatomical structure characteristics of the leaves were observed and compared, and the drought resistance of grape rootstock varieties was evaluated by principal component analysis and cluster analysis. 【Result】The results show that, the relative water content of leaves of 17 grape rootstock varieties decreased greatly under drought stress, while the relative water content of stem nodes showed two trends of small increase and decrease, and the relative electrical conductivity of leaves and stem nodes showed different degrees of increase. And the order of sensitivity of leaf anatomical structure indexes to drought stress was:R/S> CTR> SR> TUE> TL> TLE> TP> TS. 【Conclusion】 The index of leaf anatomical structure is closely related to the drought resistance of grape rootstocks and can be used to identify their drought resistance. Combined with principal component analysis and cluster analysis comprehensive evaluation obtain, 1103P, 5BB and Riparia9 have highly drought resistant, 3309C, Riparia2, Riparia10 and Amurensis×Riparia4 have strong drought resistance, 1613C, Dogridge, Beta and Amurensis×Riparia1 have moderate drought resistance, Amurensis×Riparia3, Riparia7, Riparia Glorie, 101-14MG and Riparia4 have weak drought resistance, Ganzia has the weakest drought resistance.

摘要:

【目的】研究叶片解剖结构指标与葡萄砧木抗旱性之间的关系,为抗旱性葡萄品种的筛选提供便捷有效的方法。【方法】以17个葡萄砧木品种多年生田间树为材料进行干旱胁迫处理(21 d),测定其茎叶相对含水量和电导率,观测比较其叶片解剖结构特征,并结合主成分分析法和聚类分析法对各葡萄砧木品种的抗旱性进行了综合评价。【结果】干旱胁迫导致17个葡萄砧木品种的叶片相对含水量大幅度下降,茎相对含水量则出现小幅度的上升和下降两种趋势,叶片和茎的相对电导率均呈现不同程度的增加;而各项叶片解剖结构指标对干旱胁迫敏感程度的顺序为栅海比>细胞结构紧实度>细胞结构疏松度>上表皮细胞厚度>叶片厚度>下表皮细胞厚度>栅栏组织厚度>海绵组织厚度。【结论】叶片解剖结构指标与葡萄砧木品种的抗旱性关系密切,可用来鉴定其抗旱性。1103P、5BB和河岸9号的抗旱性极强,3309C、河岸2号、河岸10号和山河4号的抗旱性较强,1613C、Dogridge、贝达和山河1号的抗旱性中等,山河3号、河岸7号、Riparia Glorie、101-14MG和河岸4号的抗旱性较弱,Ganzia的抗旱性最弱。
