The results showed that plants with short stem and low gravity center, short basal internodes, long peduncle and high plant height component index were beneficial to lodging-resistance.
结果表明，矮秆、基部节间较短、重心高度较低、穗下节间较长且株高构成指数大的植株有利于抗倒伏。
The reasons were as follows: firstly, the varieties with erect and semierect panicle were dwarf with short basal internodes, which increased their lodging resistance;
主要原因在于：直立、半直立穗型品种株高偏矮，基部节间短，更有利于抗倒；
