6个蓝莓品种受低温冻害影响分析

Analysis on Six Blueberry Cultivars under the Condition of Frozen Injury

[目的]对昆明6个蓝莓品种进行了冻害情况调查,为该地区蓝莓引种及防寒工作提供参考。[方法]调查研究南高丛蓝莓品种(奥尼尔、夏普蓝、密斯黛)和兔眼蓝莓品种(顶峰、灿烂、梯芙蓝)共6个蓝莓品种受低温冻害的情况。[结果]3个南高丛蓝莓品种冻害率均达到100%,3个兔眼蓝莓品种中,灿烂冻害率高达75.0%,梯芙蓝冻害率仅为16.7%,顶峰植株未遭冻害。奥尼尔和灿烂品种受冻害的器官主要为花和果,其余3个品种受低温冻害的器官不同。[结论]不同蓝莓品种具有不同的抗寒力,露天栽培中可优先考虑顶峰和梯芙蓝品种。

[ Objective ] The six blueberry cultivars under the condition of frozen injury were investigated in order to provide reference for blue- berry introduction and winter protection. [ Method ] The six blueberry cultivars such as O ＇ Neal, Sharphlue, Misty, Climax, Brightwel], Tifblue under the condition of frozen injury were investigated. [ Result ] The results showed that O＇ Nea], Sharpblue and Misty with same freezing dam- age rate, which up to 100% , the freezing damage rate of Brightwell was 75.0%, TiflJ]ue was 16.7%, while Climax not affected by strong frosts and snowfall. The damaged organs of O＇ Neal and Brightwell were fruit and flowers, and other cuhivars had different damaged ogans. [ Conclusion] Different blueberry cultivars with different cold resistance abilities. Climax and Tifblue were priority cultivars in open cultivation.
