本试验以金光杏梅胚为材料,从落花后至成熟共13个取材时期,并采用胚龄和果实体积为衡量指标研究了金光杏梅胚挽救最适宜的时期。结果表明:金光杏梅胚挽救最佳时期是在落花后49 d左右,此期胚乳开始退化,幼胚出现畸形,核开始出现木质化,果实的体积达到总体积的77.9%,是第一个缓慢生长阶段到第二个快速生长阶段的转折期。

In this experiment, Jinguang apricot plum embryo was used as material, from 13 stages after the flowering to ripening, and embryo age and fruit volume were used as the indexes to study the most appropriate period of Jinguang apricot plum embryo rescue. The results showed that the optimum period of embryo rescue of Jinguang apricot was about 49 d after the flower inflorescence, the endosperm began to degenerate, the embryo deformity appeared, the nucleus began to lignify and the volume of fruit reached 77.9% of the total volume, which was the first one The transition from the slow growth phase to the second rapid growth phase.
