| 摘 要： | 本文通过对鲜食玉米“津鲜1号”在3个播期下的生育进程及穗分化观测研究，结果表明：津鲜1号玉米生育进程因播期不同而异，播期越早，雄稳分化时间以及从出苗到乳熟末期（采收期）所经历的时间越长，而雌穗分化持续时间稳定；3个播期叶龄指数与稳分化时期对应关系稳定，且均符合一元二次函数关系。

| Abstract: | Through observations on the growing and developing process and spikedifferentiation of the Early-ripen,Maize - "Jin xian No. 1 "planted at 3 different times,the results showed that the growing and developing process differed according to sowingtime. The earlier sowing was,the longer the male ear differentiation periods and the durationu from seeding stage to last milk stage were, but the duration of ear differentiationwas steady ; The corresponding reIationship between leaf age index and spike differentiation time at 3 sowing times was steady and was subject to parabolic function. |

| Keywords: | Sowing time freshly-eating maize spike differentiation leaf age index |
