基于2016年1月下旬福建遭遇的低温寒潮,在冻害发生后对福州杧果种质资源圃的33份品种资源的组织褐变程度和枝条恢复生长能力进行调查评价,同时对福州、云霄、东山3个种植区的主栽品种金煌杧和贵妃杧的枝组进行电导率测定,以分析品种资源和主栽品种在种植区内的抗寒能力差异性。结果表明,杧果形成层组织褐变程度达到浅褐色是个临界,33份资源主干均有活力,都能萌发抽梢,其中24份资源主枝能萌发抽梢,12份资源侧枝能萌发抽梢,仅1份资源2年生枝萌发抽梢,33份资源1年生枝均受冻死亡。在同一产区,贵妃杧相对金煌杧抗寒性强;同一个品种在3个产区的受冻表现为福州受冻最严重,其次为云霄,东山最轻。
Based on the cold and cold spell encountered in Fujian in late January 2016, the degree of tissue browning and the ability of shoots to restore growth of 33 varieties of Fuzhou Mangosteen Germplasm Resources Garden were investigated and evaluated after frost damage. At the same time, Fuzhou, Yunxiao, Dongshan The three cultivated areas of the main cultivars Jinhuang 杧 and Royal chancre Zhizhi conduct conductivity measurements to analyze the varieties of cultivars and cultivars in the cold hardiness differences. The results showed that the degree of browning of tissue formation layer of mango reached light brown, which was critical. All the 33 main stems were viable, and all of them could germinate and shoot. Among them, 24 main branches could germinate and shoot, while 12 branches could germinate , Only 1 resource 2-year-old branches germinating tips, 33 resources 1-year-old branches were frozen death. In the same producing area, Champerola pungens relative Jinhuang 杧 strong cold resistance; the same breed in the three producing areas showed the most severe cold frost damage, followed by the sky, the lightest mountain.
