通过将硬熟期的杏胚接种到ＭＳ或１／２ＭＳ培养基中经过不同时间的低温处理，结果表明：杏与桃等果树一样，其胚培养过程也需一定的低温处理才可使之正常前发生长成苗、低温处理的最佳时期为８０—９０天，其胚萌发率与成苗率分别为９５％和９５．９％（二年平均）。另外，杏胚在１／２ＭＳ培养基中比在ＭＳ培养基中萌芽、成苗率高。
The results showed that apricot, like peach and other fruit trees, needs some low-temperature treatment to make it normal when it is inoculated into MS or 1/2 MS medium. Before the emergence of mature seedlings, the optimum period of low temperature treatment is 80-90 days, the embryo germination rate and the seedling rate were 95% and 95.9% (two-year average). In addition, apricot embryos germinated in 1 / 2MS medium more than MS medium, with high seedling rate.
