药隔期低温对小麦生长发育的影响
Influences of Low Temperature in Connectivum Period on Wheat Growth and Development
摘要
Abstract
The pot culture experiment was conducted in the growth chamber to study the influences of low temperature at connectivum stage on growth , development and seed setting percentage of six winter wheat cultivars.The results showed that treating at -2℃for 24 and 48 hours at connectivum stage had different in-fluences on the growth morphology , seed setting percentage and thousand kernel weight .The seed setting per-centage of most varieties didn ’t decrease obviously after 24 hours of low-temperature stress , but decreased obviously after 48-hour stress , which indicated that the longer the low -temperature stress at -2℃, the more serious the damage to wheat was .According to the variation of seed setting percentage , the spring frost resistances of Jimai 22 and Linmai 4 were better than Yannong 19 , and that of Luyuan 502 , Jinan 17 and Zhoumai 18 were the worst .关键词
