摘要
以芥菜种子为试材,采用非培养皿法,研究了不同浓度的硫脲、KNO3和H2O2对荠菜种子发芽的影响。结果表明:经化学试剂处理后芥菜种子发芽势、发芽率均比对照有所提高,其中以0.4%的硫脲处理对促进荠菜种子发芽的效果最好,0.06%H2O2次之,最后是1.0%KNO3处理,它们在提高发芽势、发芽率及发芽指数上均有较好的效果。
Taking the seeds of Capsella bursa-pastori as materials, the effect of different concentrations of Thiourea, H2O2 ,KNO3 solutions on the germination of Capsella bursa-pastori seeds were studied by being cultured in cultured dishes. The results showed that the germination energy and germination percentage of Capsella bursa-pastori increased obviously by treating the seeds with different chemicals. The best treatment was 0. 4% Thiourea,followed by 0. 06% H2O2 and 1. 0% KNO3. They improved the germination potential,germination rate and germination index better.
