| 摘 要： | 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。

| Abstract: | Our observation showed that the aoricot fruits were born mainly by natural pollination and most fruits were born on middle and long fruit branches. Hatural premature drop appeared in stage fruit growing rapidly. The development of fruil and various parts in fruit showed a curve of "S" shape. Three growth peaks appe- ared in different parts of fruit: 1. the period of rapid growth of fruit, fruit stone and ovule; 2. the period of raoid growth of embryo; 3. the period of rapid growth of dry matter in embryo. The stage of hardening the stone began after the fruit growth stopped from late May and ended in middle June, which the ovule had grown to the mature size. |
