摘要
以优选果梅‘黔荔1号’种子为材料,研究赤霉素、低温层积和破壳处理对果梅种子萌发的影响。结果表明:以浓度为50mg/L的赤霉素溶液浸泡处理,种子发芽率最高,为32%;以150mg/L赤霉素浸泡果梅种子的适宜时间为30h;在层积时间内,以层积60d的果梅种子发芽率最高,可达33%;破壳处理可明显提高果梅种子发芽率,可达47%。
Used better sellected plant（＇Qianli No.1＇） seed from Prunus mume as materials,effect on germination rates of seeds by the method of GA3,stratification and removing endocarp were studied.The results showed that the optimal soaking concentration of GA3 was 50 mg/L,its germination rate was 32%.When soaking the seeds with 150 mg/L GA3,the suitable soaking time was 30 h.The seeds under low temperature at 4℃ could got a certain percentage of germination 33% after about 60 days.It could increase the germination rate significantly by removing endocarp,the percentage of germination reached 47%.
