【摘要】 不同消毒处理对烟草种子消毒效果的影响研究表明,在种子消毒之前,经无菌水浸泡24 h(预处理)的比不浸泡的消毒效果好;在10%H2O2、2%有效氯次氯酸钠溶液、1‰升汞3种杀菌剂中,10%H2O2消毒效果最好,种子带菌率为0%,用75%乙醇预处理可降低种子带菌率;3种消毒剂中以10%H2O2处理烟草种子发芽率最高。更多还原

【Abstract】 The effects of seed sterilization were studied by different seed sterilization methods.The results showed that sterilization of seeds soaked in aseptic water for 24 hours was better than that without soaking.Under constant temperature,the sterilization effects of three germicides(10%H2O2,2% sodium hypochlorite and 1‰ HgCl2) on tobacco seeds were studied.The results showed that 10%H2O2 had the greatest sterilization effect.The germ-bearing rate of seeds of K326 treated with 10%H2O2 was 0%.Sterilization of seeds soaked in 75% ethanol before seed sterilization decreased germ-bearing rate.The highest germination rate was observed in treatment with 10%H2O2.更多还原
