植物在遭遇冻害时，细胞内环境脱水、结晶，从而造成细胞物理性损害或死亡。

Intercellular environment would dehydrated and crystallized when plant supper from freeze injury . It is the result that cell would physically damaged and dead .

而植物要抵抗冻害，需要具备两个最基本的要素：一是避免细胞内结冰；二是提高细胞膜结构及核酸蛋白质等生命物质的低温稳定性。

There are two basic elements that plant resists the freeze injury . First , plant has to avoid ice in intracellular ; Second , plant has to improve the stabilization of the structure of the cellular membrane and biological macromolecule .

植物抗冻蛋白是从许多抗冻植物中分离的、参与植物抵御冻害反应的一类新型蛋白。

Anti-freezing proteins ( AFPs ) are the new type of proteins isolated from overwintering plants , which involve in the plant responses to low temperature stress .

由于单个的冰核细菌细胞并不具有冰核活性，因此，研究植物上冰核细菌的种群数量或密度是研究冰核细菌与植物霜冻害关系的关键。

Single cell of INA bacteria can not act as ice nucleus , therefor the key to the study on the relationships between INA bacteria and frost injury to plants is to study the population of INA bacteria .
