连翘开花结实习性与物候期的观测

采用实地观测的方法,对连翘的物候期及开花习性、果实生长发育规律进行研究,以期为提高连翘产量和研究连翘的栽培、繁殖提供依据。记录了连翘各个生长发育阶段的日照及温度条件、连翘花部特征、连翘果实生长发育动态,并研究了海拔高度对连翘坐果率的影响。结果表明,温度、日照和海拔是影响连翘生长发育的主要因素。适宜连翘种植的年平均温度为5.0~15.6℃,连翘开花结实需要充足的光照,连翘生长的最佳海拔高度为800~860m。

Observation of the Blossom and Fruiting Habit and Phenophase of Forsythia suspensa

The characteristics of the blossom,fruiting habit,phenophase and fruit growth development of Forsythia suspensa were surveyed in field to supply the foundation for increasing the output and studing cultivation and propagation.The sunlight and temperature of every growth deve-lopment phase,the flower traits and the fruit development of F.suspensa were recorded to study their effects on fruit set.In addition,the relationship of the altitude and the fruit set rate was also researched.Temperature,sunlight and a...
