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.
