摘要
腊熟期小麦的茎秆倒伏是制约小麦生产的一个重要因素。研究小麦在腊熟期造成茎倒的茎秆性状以及其他构成因素的相互关系,对于提高小麦产量以及育种效率有着非常重要的指导意义。通过对抗倒伏指数和茎秆形态特征之间关系进行研究,给出了给出抗倒伏指数与株高、穗长、各节间长、节间长度比、各节壁厚、穗重、鲜重等茎秆性状在最易引起倒伏期的相关性指标,及其相关性。
La ripe period of wheat stem lodging is an important factor restricting the wheat production. Research of wheat on the wax ripeness stems down the relationship between yield and other factors, has a very important guiding significance on improving the efficiency of production and breeding。Through against the lodging index and stem to study the relationship between morphological characteristics, gives the lodging resistance index is given with plant height, spike length, internode length, internode length ratio, the section thickness, spike weight, fresh weight of stem traits in the most easy cause lodging phase correlation index, and their correlation.
