| 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。

| Abstract: | 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. |
