研究没食子酸、间苯三酚、对苯二酚、苯酚和香草醛等5种酚类化合物对苗期遭受低温胁迫的裸大麦生理特性的影响。结果表明，酚类化合物可增加低温下叶片GSH和ASA含量，维持叶片较高的SOD和CAT活性，降低叶片细胞的膜脂过氧化水平和质膜透性，提高可溶性蛋白质、热稳定性蛋白质和叶绿素含量，提高叶片的净光合速率，从而维持了膜结构与功能的稳定性，提高了裸大麦的抗寒性。在5种酚类化合物中．以间苯三酚对大多数生理特性的调节作用最大。
The effects of gallic acid, phloroglucinol, hydroquinone, phenol and vanillin on the physiological characteristics of naked barley under cold stress were studied. The results showed that the phenols could increase the content of GSH and ASA in leaves at low temperature, maintain the higher activities of SOD and CAT, lower the levels of membrane lipid peroxidation and plasma membrane permeability, and increase the contents of soluble protein, thermostable protein and Chlorophyll content, increase net photosynthetic rate of leaves, thereby maintaining the stability of membrane structure and function, improve the cold resistance of barley. Among the five phenolic compounds. With phloroglucinol most of the physiological characteristics of the regulatory role.
