摘要
利用茚三酮等方法分别测定了大叶黄杨喷施溴氰菊酯、氧乐果、吡虫啉、苦参碱和阿维菌素后,植物SOD的活性和游离脯氨酸的含量。结果表明,农药和干旱、高低温等一样,是一种胁迫因子。药后1d到10d,大叶黄杨SOD的含量均较对照有所提高,其中以溴氰菊酯和氧乐果胁迫最重,其次为阿维菌素和吡虫啉,苦参碱最轻;药后1d到10d,大叶黄杨脯氨酸的含量均较对照植物显著提高,其中,药后6d,喷施氧乐果的大叶黄杨脯氨酸含量为对照的378倍、阿维菌素为76倍、溴氰菊酯为22倍、吡虫啉为23倍、苦参碱为20倍。
Free proline content and SOD activity were measured in Euonymus japonica Thunb. by an ascorbic acid method and other methods after application of different pesticides including matrine, avermectin, imidacloprid, deltamethrin, and omethoate. Results suggested that pesticide application is a kind of stress factor similar to other stresses such as drought and high or low temperature. Between 1 and 10 days following pesticide application, SOD content of E. japonica was increased, with deltamethrin and omethoate showing the greatest effect, followed by avermectin and imidacloprid, and matrine causing the least stress. Free proline content 1 to 10 days after pesticide application was substantially increased, with omethoate, avermectin, imidacloprid, deltamethrin, and matrine causing 378-, 77-, 23-, 22-, and 20-fold increases 6 days after application.
