| 摘 要： | 以西瓜种子黑媚娘为试验材料,在70,75,80℃温度下分别处理24,48,72 h,研究不同干热处理对西瓜种子活力的影响。试验结果表明,70℃干热处理对西瓜种子发芽特性、发芽势均没有影响,75,80℃处理降低了西瓜种子活力,与对照有显著性差异。各干热处理后的种子在老化3 d后,活力大大降低。

| Abstract: | In order to study the effects of different dry heat treatments on seed vigor of watermelon, we took the seeds of watermelon cultivar Heimeiniang as test material, and put the seeds at 70 ℃, 75℃ and 80 ℃ for 24 h, 48 h and 72 h respectively. The results showed that, the dry heat treatment under 70℃had no effect on seed germination and germination energy of Heimeiniang. While the two treatments under 75℃ and 80℃ reduced the seed vigor of watermelon significantly compared with that of the control treatment. We also found that the vitality of the treated seeds greatly reduced after artificial aging for three days. |
