摘要
在山西省五寨县对中间锦鸡儿Caragana intermedia的开花习性进行观测研究,描述了中间锦鸡儿的花器构造和开花过程、开花顺序、自花授粉和异花授粉,以及日间和日内的开花规律。研究结果表明,中间锦鸡儿是雌雄同花植物,5月初开花,约4 d后开花强度达到高峰,之后开花强度逐渐下降,每天的开花高峰在12:00-14:00,开花强度与温、湿度存在一定的相关性。
Flowering habit of Caragana intermedia Kuang were studied in Wuzhai county of Shanxi province. The result described flower formation, flowering process, flowering sequence, self-pollination, allogamy, and between-day and in-day flowering pattern. The result indicated that, Caragana intermedia Kuang is a perfect plant, and begin to flower in early May. Its flwering intensity peaks after four days, then intensity drops gradually. May 8 is the peak of flowering; the daily flowing peak is generally at 12-14 o＇clock. Flowering intensity has certain correlation with temperature and humidity.
