| 摘 要： | 以多穗型玉米农华103为材料,研究单株穗数对玉米后期物质生产的影响。结果表明:单株穗数越多,玉米后期干物质积累量越大,穗部干物质积累量越大,穗部干物质占后期干物质积累总量比例越大,去穗植株的单个果穗性状均优于未去穗植株对应位置上的果穗性状。

| Abstract: | With the prolific maize Nonghua 103 as material,the effects of ear amount per plant on matter production in the later period of maize were studied.The results showed that the more ears per plant,the more dry matter accumulation in the later period of maize,the ears accumulated more dry matter and the ear proportion was more than one-ear plant.The ear characters of ear-cutting plants were better than the non-ear-cutting plants. |
