春小麦穗发芽影响因素及特性研究
Influential Factors and Characteristics of Harvest Sprouting of Spring Wheat
摘要
Abstract
The current research investigated the influence of cultivar, harvest time, temperature, and falling number on harvest sprou-ting and grain germination of spring wheat. Notable differences in harvest-sprouting resistance were observed among four cultivars of spring wheat (Kechun 1, Kehan 21, Kefeng 12 and Kehan 15). Harvest time substantially affected the rates of grain germination and harvest sprouting, which markedly increased with postponing harvest time. Each tested cultivar showed a lower rate of gain germination at 15℃ relative to 20℃;a higher temperature occurring at a later harvest time was especially favorable to germination. Falling number varied among different wheat cultivars, showing a negative correlation with the rate of harvest sprouting. The present study provided the basis for selecting wheat cultivars with resistance to harvest sprouting.关键词
