摘要
以朱砂根及其变种红凉伞为试验材料,研究了大田栽培方式下,朱砂根及其变种红凉伞在上海地区的生长习性和物候期表现,观测和记录朱砂根各时期花芽形态特征,研究了朱砂根在上海地区花芽分化过程。结果表明:大田栽培下,朱砂根的萌芽、开花和坐果等物候期都比其变种红凉伞晚,但它们的各物候期持续时间一致。通过对大田栽培的朱砂根花芽分化期观察,认为朱砂根在上海地区花芽能够正常分化,花器官能够正常分化和发育,分化时期为4—5月。
In this paper, we investigated the growth habits and phenophase of Ardisia crenata and A. crenata var. bicolor in- troduced in Shanghai, observed the morphologic character of flower bud differentiation, studied the process of flower bud differentiation. The results showed that the phenophase of A. crenata trees was later than A. crenata var. bicolor, but two kinds of trees, planted in croplands had the same long time of phenophase. The flower bud showed normal differenciaton and development in Shanghai, between April and May in a year.
