不同播期对超甜玉米穗部性状的影响研究

A study of the effects on the ear characters of super-sweet corn at different seeding time

采用粤甜3号和吉甜6号为材料,初步研究不同播种时期对超甜玉米穗部性状的影响。结果表明:不同播期超甜玉米的穗行数、穗长、行粒数变异幅度较小,穗轴重、鲜百粒重和单苞鲜重变异幅度较大;在各产量构成因素中,鲜百粒重、穗行数、行粒数对单苞鲜重的影响较大。

Based on test of Jitian6 and Yuetian3, this article studies the effects on the ear characters of super-sweet corn at different seeding time. It is found that the row number, the ear length and the kernels per row change slightly while the 100-kernel weight, the cob weight and the ear weight change greatly. Among the yield components, the 100-kernel weight, the row number and the kernels per row have greater effect on the ear weight. Low temperature at growth period suits the ear development of Jitian6, a cultivar in northern China.
