| 摘 要： | 应用哈茨木霉T2-16菌株在改良后的GPF培养基中发酵培养获得的发酵产物,对豇豆种子进行浸种处理,分析了发酵产物在种子萌发过程中主要生理生化过程的影响.结果表明,该发酵产物可增强豇豆体内超氧化歧化酶(SOD)、过氧化氢酶(CAT)和过氧化物酶(POD)等保护酶活性,有效保护种子细胞膜结构的完整性,减少了氨基酸、蛋白质、可溶性糖等胞内营养物质的外渗,从而起到提高豇豆种子活力的效果. |

| Abstract: | The fermented product of T.harzianum T2-16 strain was applied on cowpea by seed soaking.The effects on the seeds vigor were studied.The results showed that the specific activities of protective enzymes,superoxide dismutase(SOD),catalase(CAT) and peroxidase(POD)all increased.The fermented substance could also make the cell membrane permeability,decrease the conductivity rate.The contents of protein,dissoluble sugar and amino acids in cell exudates of cowpea seedlings were less than that of treated by water.T... |
