不同葡萄品种抗寒性比较研究

Study on Cold Resistance of Different Grapevine( Vitis vinifera L. ) Cultivars

[目的]鉴定新疆地区葡萄(Vitis vinifera L.)品种的抗寒力,对于品种资源的利用、品种的合理规划布局和抗寒育种及评价、推广抗寒性品种都具有重要的意义。[方法]以3个葡萄品种(红地球、里扎马特、无核紫)为试材,研究低温处理(-23、-4℃)对葡萄枝条相对电导率、可溶性糖含量、束缚水/自由水的影响。[结果]随着处理温度的降低,各品种枝条的相对电导率、可溶性糖、束缚水/自由水含量逐渐升高,但是各品种升降的速度和幅度有差异,各品种参数的升降幅度大小顺序与其抗寒性强弱顺序基本相符。[结论]检测的3个品种中,无核紫的抗寒性最强,红地球的抗寒性最弱。

[Objective] The aim was to identify different grapevine cultivars of Xinjiang area,which had important significance for cultivars resources utilization,cultivars reasonable layout,breeding cultivars with cold resistance,and evaluation and promotion the cultivars with cold resistance.[Method] Taking three grapevine cultivars （Red Globe,Rizamat,Monukka）as materials,the content of soluble sugar,relative conductivity and irreducible water/free water of grapevine branches under low temperature （-23,-4 ℃） treatments were studied.[Result]As the temperature decreasing,the relative conductivity,soluble sugar and the ratio of irreducible water to free water of three grapevine cultivars branches increased gradually,while the change speed and range were different among cultivars,the order of cultivars parameters were consistent with the cold resistance.[Conclusion] In three grapevine cultivars,the resistance to cold of Monukka was the most,while that of Red Globe was the weakest.
