外源物质对园艺植物抗冷性的影响研究进展

Research Progress on Effects of Exogenous Substances on Cold Resistance of Horticultural Plants

园艺植物生长发育对低温较为敏感,闽南气候温暖区域出现的寒潮等极端天气现象,易对蔬菜、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的前提下,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为高效、安全的方法。为了更好地认识外源物质对植物抗冷性的影响,本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。

The growth and development of horticultural plants are sensitive to low temperature.Extreme weather phenomena such as cold wave in the warm climate area of Southern Fujian is easy to have an negative impact on the growth of horticultural crops such as vegetables and fruit trees.In modern agricultural production,on the premise of ensuring the quality and safety of agricultural products,some exogenous substances are often used for root micro spray drip irrigation,leaf spraying and seed soaking,which has become a more efficient and safe method to improve plant stress resistance.In order to better understand the effects of exogenous substances on plant cold resistance,this paper reviewed the research progress of plant cold resistance mechanism and the effects of exogenous substances on plant stress resistance.
