【摘要】 对4个五味子品系的研究结果表明:五味子花粉为中型,花粉粒整齐,饱满花粉粒达95%以上;花粉量较大,每花药平均花粉量为(1.53-3.00)×105粒。培养基中蔗糖、硼酸的质量浓度对五味子花粉萌发有较大影响,50-100 g/L的蔗糖和0.2 g/L的硼酸有利于花粉管萌发和生长;花粉的适宜萌发温度为20-25℃。五味子的杂交结实率明显高于自交结实率,其中杂交的花朵结实率为自交的1.7-2.8倍,心皮结实率为自交的3.5-6.5倍;五味子的传粉方式主要为虫媒传粉,可能存在一定程度的风媒传粉。更多还原

【Abstract】 The studies of four strains of Schisandra chinensis(Tnrcz) Baill show that pollen size is medium and uniform and plump pollens exceed 95%. Pollen is of large quantity,and the average of each anther dust ranges between 153 thousand and 300 thousand.The concentration of sucrose and boric acid in medium largely affects the germination of Schisandra chinensis(Tnrcz) Baill. 50～100 g/L of sucrose and 0.2 g/L of boric acid in medium makes for pollen germination and the appropriate temperature is 20～25℃.In addition,the fruiting rate in cross-fertilization is higher than in self-pollination.The fruiting rate of flower and carpel in cross-fertilization is 1.7～2.8 and 3.5～6.5 times of that in self-pollination respectively.更多还原
