摘要
毛白杜鹃‘紫萼’在杭州地区于8月初开始花芽的形态分化,至9月中旬完成花瓣、花萼、雄蕊和子房的分化,到10月初形成发育较完全的小花。在相对光强65％的生境中每枝着花数最多,而在较低光强的生境中(<4％)不能形成花芽。在气温20～24℃及伴随着充足的雨量和高的空气相对湿度下,花芽的分化及发育加速。
Azalea 'Plenum' initiates floral buds in Hangzhou at the beginning of Aug. At the middle of Spet, the primordia of petals. sepals, anthers, and pistils are formed. The development of complete floral buds begins at the beginning of Oct, The largest number (3.5) of floral buds per shoot occurs in the habitats with 65.23% relative light intensity. However, there are no floral buds in habitats with lower light intensity. Floral bud formation is accelerated under the environmental conditions with temperature of 20-24℃, plentful rainfall, and high air humidity.
