摘要:
以3个草莓品种的叶片为试材，采用传统的石蜡切片法，研究冬季大棚栽培不同草莓品种对白粉病的抗性的影响并分析其叶片的解剖结构的差异。结果表明：3个草莓品种的抗性差异显著，抗白粉病能力最强的是‘枥乙女’，其次是‘红颜’，最差的为‘章姬’。筛选出3个品种的草莓叶脉的厚度，主维管束的长度，主维管束的宽度，栅栏叶肉的厚度和叶片栅栏组织的比例等指标差异性极强。同时发现栅栏组织的厚度和在叶片栅栏组织的比例可能是影响草莓的抗病性的关键性指标。草莓的栅栏组织的厚度可以采取作为草莓抗白粉病的品种筛选的早期识别指标，从而为冬季大棚栽培草莓提供理论依据。
Abstract:
Taking the leaves of three strawberry cultivars as the materials,the effect of different cultivars on powdery mildew resistant in greenhouse in winter were studied by using traditional paraffin method and the anatomical structure of strawberry leaves was compared.The results showed that the sequence of resistance capacity to powdery mildew from the most resistant to the least was ‘Benihoppe’,‘Toyonoka’ and ‘Zhangji’.Indicators of the resistance to powdery mildew were selected，including the thickness of leaf veins，the length of main vascular bundles，the width of main vascular bundles，the thickness of palisade mesophylls and the ratio of palisade tissues in leaf.Also it was speculated that the thickness of palisade tissues and the ratio of palisade tissues in leaf might be key impact indicators for disease resistance of strawberry.The thickness of palisade tissues of strawberries might be taken as the indicator of resistant cultivars in the early identification.The data of suitable strawberry cultivars was provided for planting in greenhouse in winter.
