- 摘要:
- 以不同储藏年份无籽西瓜“新秀”新、陈种子为试材，以锯末灰为引发基质，研究了锯末灰引发处理对无籽西瓜种子萌发及其种子浸出电导率、脱氢酶活性、蛋白质含量的影响。结果表明：锯末灰引发使新、陈种子发芽率、发芽指数，活力指数提高，种子浸出液电导率降低，呼吸代谢增强，种子活力提高；但新、陈种子的引发效果有差异，锯末灰引发对新种子在亚适宜温度下发芽率无显著影响。
- Abstract:
- Taking various storaged seeds(aged seeds and new seeds) of triploid water melon as materials,with sawdust as priming matrix,the effect of sawdust priming on the seed germination,seed leaching conductivity,dehydrogenase activity and protein content of triploid water melon were studied.The results showed that,seed germination rate,germination index and vigor index of aged and new seeds were increased,respiratory metabolism and seed vigor increased.While there were difference in priming effect between aged and new seeds,its no significant difference on germination of new seeds under unsuitable temperature.
