摘要
采用比色法,初步研究了绿色木霉菌Tv04-2菌株固体发酵产物对人参幼苗几种防御酶活性的影响。通过测定表明,用木霉菌发酵物处理后的人参幼苗叶片中的苯丙氨酸解氨酶(PAL)、过氧化氢酶(CAT)和超氧化物歧化酶(SOD)酶活性分别较对照提高了44.0%、12.8%、34.0%,表明木霉菌Tv04-2菌株具有促进人参抗病性的潜能。
To study the effects of fermentation solid of Trichoderma viride strain Tv04-2 on activities of defense enzymes of ginseng through colorimetry. Results showed that, after inoculated with the ferment of Trichoderma viride strain Tv04-2, the activities of phenylalanine ammonialyase （PAL）, catalase （CAT） and superoxide dismutase （SOD） were enhanced 44.0%, 12.8%, and 34.0% over control, respectively. The results indicated that Trichoderma viride strain Tv04-2 has great potential in promoting the disease resistance of ginseng.
