摘要
为探索不同浓度次氯酸钠对烟草无菌苗生长的影响,分别用25%、30%及40%NaClO处理烟草种子30min,然后,测定了无菌苗的生物量、根系活力、叶绿素含量、根冠比、根长和株高等生理指标。结果表明,在处理30min的情况下,25%NaClO处理较为适宜,无菌苗的各项生理指标均有较好的表现。
To explore different concentrations of sodium hypochlorite on the growth of aseptic tobacco seedling,tobacco seed was treated with 25%,30% and 40% NaClO,for 30min.Physiological indicators such as biomass,root activity,chlorophyll content,root top ratio,root length and plant height were measured on aseptic tobacco seedling.The results showed that the treatment of 25% NaClO was the proper one regarding the aseptic tobacco seedling growth under 30min surface sterilization time.
