Abstract:
In 2012，from April to August，the flowering phenology process of Bergenia crassifolia (L.) Fritsch in Kanas Lake，Altay City，Kuitun City and Urumqi was observed respectively,the effect of floral characters,focundity,and environment changes on blossom biology characteristics of Bergenia crassifolia (L.) Fritsch were stuided.The results showed that the blooming period of introduced Bergenia crassifolia (L.) Fritsch was in early Spring to middle May while the blooming period of wild ones was in middle May to late June or early July.Compared with wild ones，introduced ones had shorter and larger scapes，larger calyxes and shorter anthers stamen.Their scape height and petal length difference were extremely significant，which was related to altitude，mean annual temperature，annual precipitation and annual evaporation.The fruit of introduced ones was smaller than that of wild ones，with heavier seed and higher abortion rate.These results had provided a theoretical basis for deep search for the reproductive ecology characteristics of Bergenia crassifolia (L.)
