【摘要】 以风味皇后和恐龙蛋2个杏李品种为试材,研究了大石早生、黑宝石、小黄李和蓝宝石4个李品种花粉对其坐果率的影响。结果表明:风味皇后和恐龙蛋2个杏李品种的自花授粉坐果率均为0,说明2品种自花不实,属异花结实果树。用大石早生和黑宝石的花粉为风味皇后授粉,坐果率分别为13.33%和5.83%,均极显著地高于风味皇后自花授粉的坐果率,且均能达到生产上要求的产量,认为上述2个李品种均可作为风味皇后的授粉树。而以小黄李和蓝宝石2个李品种为风味皇后授粉及该研究的4个李品种为恐龙蛋授粉,坐果率均为0,认为小黄李和蓝宝石2个李品种不能作为风味皇后的授粉树;而该研究的4个李品种不能作为恐龙蛋的授粉树。更多还原

【Abstract】 Took two varieties of plum and apricot Fengweihuanghou and Konglongdan as testing materials, studied pollen of four Plum cultivar Dashizaosheng, Black jewel, Xiaohuangli and Blue jewel on their setting rate. The results showed that fruit setting percentage of self-pollination of Fengweihuanghou and Konglongdan were 0, which indicated that they do not set fruit during self-pollination; they are cross-firm fruit trees. With pollen of Dashizaosheng, Black jewel pollinate respectively for Fengweihuanghou, setting rate were 13.33% and 5.83%, which were significantly higher than the setting rate of self-pollination of Fengweihuanghou, and they can achieve the output of production requirements. So they were taken for pollinizer of Fengweihuanghou. Then Xiaohuangli and Blue jewel pollinate for Fengweihuanghou, and the four Plum cultivar pollinate for Konglongdan, their setting rate were all 0, So Xiaohuangli and Blue jewel can not been arranged pollinizer for Fengweihuanghou. In addition the four plum cultivar can not been arranged pollinizer for Konglongdan.更多还原
