摘　　要：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。Embryo of‘Jinguang’plum was used as materials and 13 sampling dates from pollination to maturation were adopted to study the best date of embryo rescue,using embryonic age and fruit volume for measurement index.The results showed that the best time of embryo rescue was 49 days after pollination.In this period,endosperms began to degeneration,young embryo abnormality and the stone lignifications began.Fruit volume reached 77.9 % of the total volume,and this time was the transition of the first slow growth period and the second fast growth period.
