| 摘要: |
| 园艺植物的生长发育对低温较为敏感，在闽南温暖气候地区出现寒潮等极端天气现象，对蔬菜、果树等园艺作物生长产生不利影响。在现代农业生产中，在保证农产品质量安全前提下，常利用一些外源物质进行根部微喷滴灌、叶片喷洒、浸种等，这已成为一种提高植物抗逆性较高效、安全的方法。为了更好认识外源物质对植物抗冷性影响，此文综述了植物抗冷机制及外源物质影响植物抗逆性的研究进展。 |

| Abstract: |
| The growth and development of horticultural plants is very sensitive to low temperature.In southern region of Fujian province, If cold air outbreak or other extreme weather happens,will makes negative influence to vegetables and fruit trees .In modern agricultural production,under the premise of the quality and safety of agricultural products,people usually use exogenous materials to root-irrigation,spraying,soaking of seeds and etc.Application of exogenous materials becomes an efficient and safety way.In order to know the impact of exogenous materials to cold resistance of horticultural plants better,this paper reviewed the research progress of plants’cold resistance mechanism and the impact of exogenous materials to plants. |
