李品种花粉对杏李坐果率的影响

以风味皇后和恐龙蛋2个杏李品种为试材,研究了莫尔塔尼、秋姬李、红心李、辽宁1号和安哥诺5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,说明两品种自花不实,属异花结实果树。用莫尔塔尼、秋姬李、红心李的花粉为风味皇后授粉,坐果率分别为11.67%,8.33%,5.83%,均极显著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3个李品种均可作为风味皇后的授粉树。而辽宁1号和安哥诺2个李品种为风味皇后授粉,莫尔塔尼、秋姬李、红心李、辽宁1号、安哥诺5个李品种为恐龙蛋授粉,坐果率均为0,认为辽宁1号和安哥诺2个李品种不能作为风味皇后的授粉树,莫尔塔尼、秋姬李、红心李、辽宁1号、安哥诺不能作为恐龙蛋的授粉树。

Experimental Study of Plum Pollen on Fruit Set Percentage of the Prunus species×Prunus armeniaca L.

The effects of pollens of five Plum cultivars,Moertani、Qiujili、Hongxinli、Liaoning1 and Angenuo,on the rate of fruit set of the two varieties of Prunus species×Prunus armeniaca L.-Fengweihuanghou and Konglongdan were studied.The fruit setting percentage of self-pollination of Fengweihuanghou and Konglongdan was 0,which indicated that they are self-unfruitfulness and cross fruitful fruit plant.With pollen of Moertani、Qiujili and Hongxinli pollinate for Fengweihuanghou,fruit setting percentage were 11.67%,8.33% and 5.83%,respectively,which were significantly higher than that of self-pollination of Fengweihuanghou,and met the production need,so they were taken as pollinizer for Fengweihuanghou.While Liaoning1 and Angenuo pollinated for Fengweihuanghou,and all of the five Plum cultivars pollinated for Konglongdan,their fruit setting percentage were all 0,so Liaoning1 and Angenuo could not be used as pollinizers for Fengweihuanghou.And the other five Plum cultivars couldnt be used as pollinizers for Konglongdan.
