摘要: 单叶蔷薇花芽分化从3月下旬开始至4月下旬完成, 历时30 d, 其过程可分为形态分化前、苞叶原基分化期、萼片原基分化期、花瓣原基分化期、雄蕊原基分化期、雌蕊原基分化期。其中花瓣原基的分化只进行1次, 这是形成单轮花瓣的原因。各花器官原基起源于花分生组织的边缘区细胞。生殖生长锥直径和细胞数的增加在生长锥膨大期和心皮分化期较高。

Abstract: The flower bud differentiation process of Rosa persica lasted for about 30 days from bract promordium differentiation in late March to carpel promordium formation in late Ap ril. The p rocess could be divided into six phases: before differentiation, bract differentiation phase, sepal differentiation phase, petal differentiation phase, stamen differentiation phase and pistil differentiation phase. Of them one time was occurred in differentiation of sepal primordium, and itmight be the reason of forming the simple layer of sepal. An larges of each floral promordium originated in peripheral zone cells of floralmeristem . The increase of cell number and diameter of apical pointwas higher in both extension phase and carpel differentiation phase.
