- 摘要:
- 在休眠初期，果桑极易受到秋季低温冻害。以14个果桑品种为材料，在低温胁迫下，测定与抗寒性相关的6个生理生化指标，结合相关性检验，采用隶属函数法进行抗寒性综合评价，以期筛选抗寒性强的优良品种。结果表明：14个果桑品种可划分为3级，其中I级高抗寒型3个品种，II级抗寒型7个品种，III级低抗寒型4个品种。
- Abstract:
- Low temperature of the late autumn is very harmful to the growth of mulberry during early period of the rest.In order to screen the cold tolerant mulberry varieties,14 mulberry varieties using subordinate function method combined with correlation analyses based on six physiological and biochemical indexes relevant to cold tolerance under low temperature treatment were comprehensively evaluated.The results indicated that 14 mulberry cultivars were divided into three groups of cold tolerance,the group I had three varieties with high cold resistance,the group II had seven varieties with moderate cold resistance,and the group III had four varieties with low cold resistance.
