本文的调查和观测结果表明:山杏以中、长果枝结果为主,株间自然传粉是结实的主要途径,自然落果发生在果实速长期。山杏果实及其各部分的生长动态均呈“S型曲线。各部分出现生长高峰的时期大致分三个阶段:第一阶段是果实、果核和胚珠的迅速增大,以及青皮和核壳的迅速增长;第二阶段是胚的迅速增长;第三阶段是胚中干物质量的迅速增长。硬核期从果实基本停长后的5月下旬开始,至6月中旬结束,此期胚球已达到成熟时的大小。
In this paper, the survey and observation results show that: the apricot to medium and long fruiting branches results mainly between strains of natural pollination is the main way of fruiting, natural fruit occurs in the fruit long-term. The growth dynamics of the apricot fruit and its parts showed a “S-shaped curve.” The growth peak of each part was roughly divided into three stages: the first stage was the rapid increase of fruit, fruit and ovule, Of the rapid growth of the second stage is the rapid growth of embryos; the third stage is the rapid growth of dry matter in the embryo. Hard stage from the basic halt in the fruit after the start of late May to mid-June, the embryo Has reached the size of maturity.
