摘　　要：对 1个欧洲杏品种和 2个中国杏品种的花芽分化解剖学观察结果表明 ,中国杏花芽分化的各时期均早于欧洲杏 ,各阶段持续时间也比后者短。 3个品种于 9月下旬开始出现雌蕊畸变。冬季 ,杏花芽继续发育 ,从 11月至翌年 1月芽体积增大 2 0 %～ 2 5 %。In the experiment,one European apricot variety and two Chinese apricot varieties were selected and the processes of differentiation and development of the flower buds were observed anatomically.The resultshows:the Chinese apricot s flowerbuds differentiated earlier and quicker than the European apricot.The pistiles on the three cultivars malformed from late September.In winter,the flower buds of apricot developed slowly and continually.The size of the buds increased twenty percentto twenty- five percent from November to the next January.
