猕猴桃是雌雄异株植物,其雄株上雄花的雄蕊周围具有退化的子房;雌株上雌花的子房周围虽有雄蕊,但这些雄蕊没有花粉,不能受精。因此,为使猕猴桃挂果,同一猕猴桃园内必须有雌株和雄株。雄株的比率一般为15—20%。日本由新西兰引进的猕猴桃主要雌性品种有:海沃德、布鲁诺、艾博特和蒙蒂。雄性品种有马图阿与唐木里。雌性品种概要海沃德品种的树势较弱,与其它品种相 Kiwifruit is a dioecious plant with degenerated ovary around the stamens of the male flowers on male plants; although the stamens are present around the ovary of the female flowers on the female plants, these stamens have no pollen and can not be fertilized. Therefore, in order to make kiwifruit fruiting, the same kiwifruit park must have female and male plants. The male ratio is generally 15-20%. The main female species of kiwifruit introduced by New Zealand from Japan are Hayward, Bruno, Abbot and Monti. The male breeds are Matuha and Tangmuri. Summary of Female Breeds Hayward breeds have a weaker tree vigor than other breeds
