抗寒性是油茶引种能否成功的主要指标。尤其我国山茶物种,主要分布于南亚热带地区,在系统发育中形成了特有的适应性,但往往抗寒性较差,有必要进行抗寒程度的分析。油茶叶片与环境的接触面最大,能否抗寒主要表现在叶和幼茎上。因此,对油茶叶片进行组 Cold resistance is the main indicator of the success of introduction of Camellia oleifera. In particular, Camellia species in our country are mainly distributed in the southern subtropical region, forming unique adaptability in phylogeny, but they often have poor cold resistance, so it is necessary to analyze the degree of cold tolerance. Camellia leaves the largest contact surface with the environment, whether the main performance of cold in the leaves and young stems. Therefore, the group of Camellia leaves
