摘 要：
试验以两种类型野生杏(甜仁杏和苦仁杏)种子为试验材料,采用GA3与低温层积相结合的综合性处理方法,研究对打破两种类型野生杏种子休眠的效果,进行发芽率与培根伸长的统计分析。以低温层积处理的作为对照,GA3与低温层积相结合对打破野生甜仁杏种子休眠提高其发芽率及胚根生长有极显著的促进作用,其发芽率与胚根长度最大分别提高到对照的2.9和4.6倍,野生苦仁杏在100 mg/L GA3浸种12 h结合低温层积时其发芽率略有提高,其胚根伸长最大达到对照的2倍。上述结果说明低温和GA3综合处理对打破甜仁杏的休眠有增益效应而对苦仁杏则没有明显的效果。

摘 要：
The experiment aimed to examine the effects of stratification combined with GA3 treatments on breaking dormancy of two different types of wild apricot(Armeniaca Vulgaris Lam.),sweet and bitter kernel type.Both of those two types were soaked in 100 mg or 200 mg /L GA3 solutions for 12 h or 24 h respectively combined with stratification treatment at-4°C for 30 days.The germination percentage and the elongation rate of radicles were increased by 2.9 and 4.6 times in comparison with the solely stratification treatment in seeds of sweet kernel type.And for bitter kernel type,the germination percentage was slightly increased under 100mg/L GA3 for 12h combined with stratification treatment,and the elongation rate of radicle was increased by 2 times.These results indicated that the method of treatment with low temperature and GA3 had more beneficial effect on breakage dormaey of sweet apricot kernel than that of bitter one .
