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。
Two types of wild apricot (sweet and blue almond and sweet almond) seeds were used as experimental materials, the effect of breaking the dormancy of two types of wild apricot seeds was studied through the comprehensive treatment of GA3 and cold stratification. Statistical Analysis of Rate and Bacon Elongation. As a control, the combination of GA3 and low temperature stratification could significantly improve the germination rate and radicle growth of wild sweet apricot seeds, and the germination rate and radicle root length increased to Compared with 2.9 and 4.6 times of the control, the wild bitter apricot slightly increased its germination rate when it was immersed in 100 mg / L GA3 for 12 h with low temperature stratification, and the elongation of the radicle was twice that of the control. The above results show that the combination of low temperature and GA3 has a gain effect on breaking dormancy of sweet apricot while there is no obvious effect on it.
