为提高休眠期春菜种子的发芽率,分别采用低温预处理、不同培养温度、不同含量植物生长调节剂和过氧化氢水溶液等处理刚收获的春菜种子,以打破种子休眠期。结果表明:4℃预先处理1 d 对提高休眠期的春菜种子发芽率影响显著;25℃适宜春菜种子发芽,温度过高或过低都会抑制种子的发芽;30 mg·L-1 GA3处理能促进休眠期春菜种子发芽;2,4-D 处理休眠期春菜种子,质量浓度低者促进发芽,高者抑制发芽;0.5%~2% H2 O2浸泡2 h 对春菜种子的发芽有促进作用。
為提高休眠期春菜種子的髮芽率,分彆採用低溫預處理、不同培養溫度、不同含量植物生長調節劑和過氧化氫水溶液等處理剛收穫的春菜種子,以打破種子休眠期。結果錶明:4℃預先處理1 d 對提高休眠期的春菜種子髮芽率影響顯著;25℃適宜春菜種子髮芽,溫度過高或過低都會抑製種子的髮芽;30 mg·L-1 GA3處理能促進休眠期春菜種子髮芽;2,4-D 處理休眠期春菜種子,質量濃度低者促進髮芽,高者抑製髮芽;0.5%~2% H2 O2浸泡2 h 對春菜種子的髮芽有促進作用。

In order to improve the germination rate of dormant Brassica juncea seeds, low temperature pretreatment,different culture temperatures and different concentrations of plant growth regulators and hydrogen peroxide were used to treat the seeds of Brassica juncea just harvesting,respectively,for breaking the seed dormancy.The results showed that there was significant influence on improving germination rate of the dormant Brassica juncea seeds at 4℃pretreatment for 1 day;It was appropriate for germination of Brassica juncea seeds when treated at 25℃,and the germination of seeds would be inhibited by higher or lower temperature;Among different treatments of GA3 ,30 mg·L-1 GA3 was proved to promote germination of the dormant Brassica juncea seeds;when treated by 2,4-D,the germination of Brassica juncea seeds was accelerated by low concentration,and inhibited by high concentration.It could also promote the Brassica juncea seeds germination when using 0.5% -2.0% H2 O2 soaking treated for 2 h.
