摘要
研究了杂交水稻种子在不同的热风干燥条件下，对其发芽特性的影响。结果表明在一定范围内，热风干燥温度和时间与种子发芽率、发芽势负相关。愈接近于自然干燥温度（30～40℃）的处理，种子发芽特性愈好。杂交稻种子＜60℃的热风干燥处理，对种子发芽特性无显著影响。
Effects of the different temperatures under hot-wind drying onthe germination characteristics of hybrid rice seeds were studied. Theresults showed that the temperature and time under hot wind drying werenegatively eelative to the germination potencial and rates. The nearerto the natura1 ones (30~40℃ ) the temperature-drying were, the;higherthe germination potencial and rates were. Treatments from 30 to 60℃had no significant effects on germination characteristics.
