- Abstract:
- 3 species，13 walnut cultivars in seedling were used as experimental materials.Leaf tissue structure indexes were screened via coefficient of variation，analysis of correlation and hierarchical cluster analysis，and comprehensive evaluation on cold resistance for each variety was done by subordinate function.The results showed that organizational structure loose degree，spongy tissue and leaf thickness were the main factors related to the hardiness；the cold resistance for 13 cultivars was in order of ‘Liaohe No 4’>‘Wen 185’>‘Xinxin No 2’>‘Tibet walnut’>‘Tie walnut’>‘Maisuihutou’>‘Yunxin 301’>‘Yunxin Gaoyuan’>‘Yunxin 306’>‘Yunxin Yunlin’>‘Yangbipao Hetao’>‘Yangjiang’>‘Yangza No.1’；the cold resistance for 3 species was in order of Juglans regia>Juglans hopeiensis>Juglans sigillata.
