中文摘要：

为给扁桃的驯化栽培和开发利用提供理论依据，采用石蜡切片法，对新疆野生邑旦杏花芽形态的分化过程进行了观察与研究。结果表明：新疆野生巴旦杏花芽形态的分化时期可分为花芽分化初期、花萼分化期、花瓣分化期、雄蕊分化期、雌蕊分化期等5个时期；6月中旬开始进入花芽形态分化期，从花芽开始分化到雌蕊原基分化形成的各分化时期有重叠现象，整个分化时期集中在7月上旬至9月上旬；完成花芽形态分化所需时间为90～100d。

英文摘要：

In order to provide a theoretical basis for domestication, cultivation, development and utilization of almond, morphological differentiation of flower bud in wild almond in Xinjiang was observed and researched by paraffin section method. The results indicated that morphological differentiation of flower bud could be divided into 5 stages： initial flower bud differentiation, sepal differentiation, petal differentiation, stamen differentiation and pistil differentiation. Morphologie differentiation of flower bud started from the middle of June, and the whole process was concentrated from early July to early September. The differentiation stages appeared overlapping. It need take 90-100 days to finish morphological differentiation of flower bud.
