9个菜心品种耐寒性评价与聚类分析
Evaluation of Cold Tolerance and Cluster Analysis of Nine Flowering Chinese Cabbage Cultivars
摘要
Abstract
The content of proline,relative electrical conductivity,survival rate,early bolting rate and chilling injury index were measured in nine flowering Chinese cabbage cultivars,and their cold tolerance were evaluated and conducted cluster analysis.The results showed that the cold resistance of cabbage was proportional to proline content and survival rate at low temperature,but inversely proportional to relative electrical conductivity,early bolting rate and chilling injury index.The chilling injury index of flowering Chinese cabbage was significantly negatively correlated with proline content and survival rate,and had significantly positive correlations with relative electrical conductivity and early bolting rate.The results of cluster analysis showed that Jianye 40 Days,Youlücutai and Sijiu-19 were non-cold-resistant type,and Youlü 70 Days,Youlü 701 and Youlü 702 were relatively more cold-resistant type,Youlü 80 Days,Chixin 4 and Youlü 802 were cold-resistant type.The cold-resistant and late-flowering cabbage varieties,Chixin 4 and Youlü 802,were suitable for cultivation in early spring and late autumn in Shandong and surrounding areas.关键词
