测定和分析杂交水稻干种、湿种和芽种在水温和气温35～85℃高温条件下处理10 min和1 h的发芽率,结果表明:杂交水稻干种忍耐高温能力最强,芽种忍受高温能力最弱;水温比气温更易使种子发芽率下降;温度超过一定范围,发芽率随温度升高和处理时间延长而迅速下降。为杂交水稻种子科学地浸种催芽提供了参考。 Determination and analysis of hybrid rice dry, wet and bud seedlings in the water temperature and air temperature 35 ~ 85 ℃ under high temperature for 10 min and 1 h germination rate, the results showed that: dry hybrid rice varieties have the highest ability to endure high temperature bud endurance The weakest high temperature ability; the water temperature is easier than the temperature to make the seed germination rate to drop; When the temperature exceeds a certain range, the germination rate decreases rapidly with the temperature increase and the processing time prolongs. It provides a reference for the seed germination of hybrid rice seeds scientifically.
