| 摘 要： | 通过田间试验研究了苗期低温对23个早稻品种农艺性状及产量性状的影响。结果显示:苗期低温对水稻苗期株高影响较大,对少数品种的秧苗叶色有影响,对水稻单株有效穗数的影响也较大,但对后期的株高、生育历期、穗粒数、结实率及千粒重均没有明显的影响。

| Abstract: | The effects of low temperature at seedling stage on the agronomic traits and yield -related traits of 23 early rice vari-eties were studied through field tests .The results indicated that： the low temperature at seedling stage had great influences on the plant height of rice seedlings , as well as the number of effective spikes per rice plant , and it also had effect on the seedling leaf color of few varieties, but it had no obvious influences on the final plant height , growth duration, number of grains per spike, seed setting rate, and 1000-grain weight of rice . |
