【目的】研究紫杏花芽形态分化调研,掌握紫杏与普通杏和樱桃李间的花芽形态分化特性及差异,为紫杏的开发利用提供理论参考。【方法】观察测量紫杏花芽大小及外部形态,采用常规石蜡切片法观察花芽内部形态分化特性。【结果】叶城紫杏的花芽为红褐色,呈椭圆锥形,长为3.06 mm,宽为1.65 mm,6月下旬进入分化初期,7中旬进入萼片分化期和花瓣分化期,8月上旬进入雄蕊和雌蕊分化期,7到9月是花芽分化盛期,10月中旬完成雌蕊分化,各分化时期有交错重叠的现象。【结论】叶城紫杏从花芽开始分化到雌蕊分化完成共需100 d,较晚熟佳娜丽长30 d,较黄果樱桃李长10 d,且叶城紫杏进入各分化阶段的时间及整体分化进程,均要晚于晚熟佳娜丽和黄果樱桃李。
【OBJECTIVE】 To investigate the morphological and morphological differentiation of purple apricot flower buds, and to understand the morphological and differentiation characteristics of flower buds between purple apricot and common apricot and cherry plum, and to provide a theoretical reference for the development and utilization of purple apricot flower. 【Method】 The size and external shape of buds of purple apricot were observed and observed. The morphological differentiation of flower buds was observed by conventional paraffin section method. 【Result】 The flower bud of Yecheng purple apricot was reddish brown in color with oval conical shape, 3.06 mm in length and 1.65 mm in width. The flower bud entered the early stage of differentiation in late June, and entered the sepal differentiation stage and petal differentiation stage in mid-seventh. Stamens and pistil differentiation period, July to September is the peak of flower bud differentiation, pistil differentiation completed in mid-October, the differentiation of staggered overlap phenomenon. 【Conclusion】 It is 100 days to complete the differentiation of Pseudostellariae Blossomed from flower bud to pistil and 100 d compared with that of Late-maturity Charlene for 30 days, The overall process of differentiation, are later than Late Maturity good Naili and yellow cherry plum.
