为在一定穗数基础上促进穗大粒多,从研究小麦穗部性状着手,分析了麦穗大小、籽粒多少的成因,以此来探讨促进穗大粒多的关键时期与措施.一、麦穗大小与小穗多少的关系从我校泰山1号亩产900斤的高产田和亩产600斤的中产田随机取样500穗,除去缺粒和有损伤的外,实际分析穗数为428个.这些样本的每穗总小穗数,最多的23个,最少的13个.
In order to promote a large number of spikelets on the basis of a certain number of spikes, starting from the study of the ear traits of wheat, the causes of the size of the spike and the number of the grains were analyzed to discuss the key period and measures to promote the spikelet size.First, The number of spikelets and spikelets from the Institute of Taishan No. 1 per mu yield of 900 pounds of high yield field and yield of 600 pounds of middle-yield field random sampling 500 spike, remove the missing and damaged, the actual analysis of the spike to 428. These The total number of spikelets per panicle in a sample, up to 23 and at least 13.
