现在，花蕾绽开了。我们能够看到，绿色的包裹物或者说杯形结构已经向后弯曲。此时，我们会注意到，这种杯形结构实际上由五片部分连接的绿色萼片组成。

同时，萼片中叶绿素a含量的动态变化与Fe含量的动态变化呈显著性正相关，表明萼片中大量的Fe可能用于叶绿素a的合成。

其中雄蕊分化期、雌蕊分化期分化速度最快，持续时间仅为3～5d，而从花序原基分化期至小花花萼分化期分化较慢。4.萼片分化期；

The phase of carpel differentiation and pistil differentiation were were relatively short , only about 3-5 days , and the phase from inflorescence primordium differentiation to sepal differentiation is relatively long .

有时，萼片也可轻微着色以吸引昆虫进行传粉。

Sometimes they are brightly colored and attract insects for pollination .

萼片、花瓣、雄蕊和雌蕊同心排列构成完全花。

花原基形成后，随即分化出5个萼片原基突起，之后，在萼片原基突起的内侧形成5个与之互生的花瓣原基突起，并进一步向内依次分化雄蕊原基和雌蕊原基。

After formation of flower primordium . meristem is differentiated to sepal , petal , stamen and pistil .

花的分生组织进行活跃的细胞分裂，并逐步分化形成萼片、瓣、蕊和雌蕊4个器官。

Floral meristem undertake cell divisions actively and differentiate into sepals , petals , stamens and carpels gradually .

同时，其苞片原基、萼片原基、花瓣原基的分化持续时间比同花型的品种在菏泽地区的持续时间要长。

The duration of bract primordium phase , sepal primordium phase and petal primordium phase were longer than it in Heze .

萼片、花冠和雄蕊的发生式样均为五基数类型，它们各来源于花原基上分化出来的花萼原基，花冠原基和雄蕊原基。
