【摘要】 用35～65℃恒温水浴对津春5号、新白玉、津研4号3个品种的黄瓜种子进行热击处理15～40min,结果表明45℃,20min处理津研4号种子的萌芽率明显升高,达到95%,平均株高和健壮度均较好;而45℃,30min处理津春5号与新白玉种子的效果较好.浸泡(8h)加热击(20min,45℃)依次处理以上3个品种的黄瓜种子,其萌芽率分别达到68.3%,74.7%和97.7%.表明适当温度和时间的热处理可以提高黄瓜种子的萌芽率.更多还原

【Abstract】 Three different varieties of cucumber seeds were treated with heat shock under the water temperature from 35～65℃for 15～40min.It was found that germination rate of Jinyan No.4 cucumber seeds increased considerably to 95% under the temperature 45℃with the heat shock for 20min,and the average height and sturdiness of these plants were also rather good. While the other two varieties(Jinchun No.5 & Xinhaiyu) need to be treated under a temperature of 45℃with the heat shock for 30min if a satisfying result is wanted of them.The germination rates reached 68.3%,74.7% and 97.7% respectively after the three varieties of cucumber seeds were soaked in water for 8h,and then treated by heat shock under the water temperature of 45℃for 20min.The experimental results show that the germination rate of cucumber seeds improves if they are subjected to a proper duration of heat shock under a proper temperature.更多还原
