晚霜冻害对不同类型小麦产量性状的影响
Influence of Spring Frost on Different Ear Types of Wheat Yield Component
摘要
Abstract
Through low temperature processtion of simulated natural spring frost damage in artificial intelligence frost box to the big ear (s9538, Lankao 906), middle ear (Yumai 21,Shaan 225),multi-spike (Linfen 7203, Luzi 0885299) types of wheat varieties, the changes in their production factors were studied. The result showed that multi-spike type wheat (Linfen 7203, Luzi 0885299) after the spring frost damage treatment got more yield than the others. Spikes per plant of multi-spike type wheat showed the biggest increase, with 32.98％ and 37.19％ for Linfen 7203 and Luzi 0885299 compared to the untreated, respectively,and the yield of per plant was increased by 36.36％ and 38.40 ％. Grain weight of wheat after the treatment showed decreased tendency,multi-spike wheat (Linfen 7203, Luzi 0885299) reduced with the maximum rate and middle ear wheat (Yumai 21, Shan 225) reduced with the minimum rate. The grain number per ear of middle ear wheat after treatment (Yumai 21, Shaan 225) were decreased but the others were increased, and multi-spike wheat (Linfen 7203, Luzi 0885299) showed the biggest increase.关键词
