高粱抗倒性可分为两种类型，一种是韧性抗倒，一种是刚性抗倒。韧性抗倒与很多形态性状有关，降低株高、增加茎粗和穗柄粗、缩短节间长度和穗柄长、提高茎干物质及糖度有利于抗倒性的提高。刚性抗倒不能完全用形态性状来衡量。增加茎容重、缩短茎基部节间的长度、提高茎基部叶鞘层数、增加茎壁厚度、提高灌浆期干物质向茎部的分配率、茎壁及髓部单位面积维管束的数量多且大、茎部可溶性糖及总糖含量高等有利于刚性抗倒。
Sorghum lodging resistance can be divided into two types, one is toughness lodging, one is rigid lodging. Resistant to lodging and many morphological traits related to reducing plant height, increased stem diameter and panicle coarse, shorten the internode length and ear length, improve stem material and sugar content is conducive to lodging resistance. Rigid lodging can not be completely measured by morphological traits. Increasing the stem weight, shortening the length of the basal internode, increasing the number of stalk sheath, increasing the thickness of the stem wall, increasing the distribution rate of dry matter to the stem during the filling stage, the number of vascular bundles per unit area of the stem wall and the medulla more , Stem soluble sugar and total sugar content is conducive to rigid anti-down.
