摘　　要：探讨喷施茉莉酸甲酯对油茶(Camellia oleifera Abel.)幼苗叶片生理生化的影响,以湘林27号、湘林36号、长林3号和长林4号4种贵州省天柱县主栽油茶品种的2年生嫁接苗为研究材料,采用露地栽培的方法,以6种不同浓度(0、100、300、600、1 000、1 500 μmol/L)的茉莉酸甲酯处理进行试验,测定4种油茶品种叶片中抗氧化酶活性、可溶性蛋白质、可溶性糖等7个生理指标的变化情况。结果表明,100 μmol/L茉莉酸甲酯喷施处理有利于提高油茶幼苗叶片中的超氧化物歧化酶、过氧化物酶和过氧化氢酶的活性,有效降低丙二醛含量,增加可溶性蛋白质、可溶性糖和游离脯氨酸的含量。To investigate the effects of spraying methyl jasmonate on the physiology and biochemistry of oil tea(Camellia oleifera)seedling leaves,2-year-old grafted seedlings of four main oil tea varieties from Tianzhu County,Guizhou Province,including Xiang-lin No.27,Xianglin No.36,Changlin No.3 and Changlin No.4,were used as study materials.Six different concentrations(0,100,300,600,1000,1500μmol/L)of methyl jasmonate were used to determine the activity of antioxidant enzymes,soluble protein,sol-uble sugar and other 7 physiological indexes in the leaves of 4 oil tea varieties.The results showed that 100μmol/L methyl jasmonate spraying treatment was conducive to increase the activities of superoxide dismutase,peroxidase and catalase,effectively reducing malondialdehyde content,and increase the content of soluble proteins,soluble sugars and free proline in the leaves of oil tea seed-lings.
