Observation on phenological period and fruit setting characteristics of bud transmutation material of Korla fragrant pear
[Objective]The aim of this study is to understand the phenological period and fruit setting characteristics of bud changing materials of Korla fragrant pear in the hope of providing reference for improving the quality of fragrant pear.[Methods]Taking Korla fragrant pear and Korla fragrant pear bud modification materials as the research objects,the bud modification materials without artificial pollination group,common fragrant pear artificial pollination group and common fragrant pear without artificial pollination group were set,and the three groups were not sprayed with agents to promote sepal shedding.The phenological period,fruit setting rate and calyx decalication rate of the three groups were studied.[Results]The results showed that the phenological period of Korla pear bud modification material was highly coincident with that of common Korla pear,and the difference was no more than 2 d.The rate of fruit setting and calyx decalyx in the group without artificial pollination was higher than that in the normal group with artificial pollination,and the rate of fruit set-ting and calyx decalyx in the group was higher than that in the normal group without artificial pollination.[Conclusion]The phenological period of the bud changing material was basically the same as that of Korla fragrant pear.The excellent characters of the bud changing material could be directly grafted without changing the management mode of the existing fragrant pear growing area.The fruit setting rate and calyx decalyx rate of bud modified material were significantly higher than those of common Korla pears,which can effectively reduce the use of chemical agents,cut down the cost and improve the fruit quality during cultivation.
