春、夏、秋和晚秋玉米的各个播期中,以春玉米的全生育期最长,出苗至穗开始分化所需日数最多,穗分化经历日数最多。穗分化时期与展开叶两者之间表现出较稳定的同伸关系。叶龄指数与穗分化时期之间相关更为密切。
Experiment on maize(Zea mays L.)hybrid Guiding 1 was done in Guangzhou in1988 and 1989.In different sowing date,spring crop had the longest growthperiod in comparison with summer crop,autumn and late-autumn crop,also had thelongest period from seeding emergence to panicle initiation and from panicleinitiation to heading or silking.There was a synchronous growth relations be-tween the stage of panicle initiation and unfolded leaves or leaf age index.
