化学药剂处理克服香梨自交不亲和性效果研究

6种化学药剂处理香梨柱头的结果表明,化学药剂对克服香梨自交不亲和性有一定效果。不同的化学药剂其效果差异为,氯化钠+硼酸、鸭梨和砀山梨花粉浸提液处理效果较好,比对照(蒸馏水处理)差异极显著;而GA、IBA、NAA与对照(蒸馏水)处理相比差异不显著。不同化学药剂浓度的处理效果亦不同,以氯化钠5%+硼酸0.3%、鸭梨和砀山梨花粉1∶10(M∶M)处理效果最好。

Overcoming Self-incompatibility in Korla Fragrant Pear by Chemical Treatment

The effects of six chemicals on the incompatibility of Korla Pear showed that treatment of stigma with sodium chloride and Boracic acid,the water solutions extracted from Yali and Dangshan Pear Flowers,Gibberellic,indole butyric acid and naphthalene acetic acid was effective in overcoming self-incompatibility in Korla fragrant Pear,a sporophytic self-incompatibility system.Sodium Chloride and Boracic acid,the water solutions extracted from Yali and Dangshan Pear flowers were much better than other chemicals and check(diseilled water). The concent ration of the chemicals worked differently in the study,and the effective concent ration was the 5% and 0.3%of the sodium chloride and Boracic acid,1∶10(M∶M)of the water solutions extracted from Yali and Dangshan Pear flowers.
