| 摘 要： | 研究超高压压力100～500 MPa处理10 min和400 MPa处理0～15 min对壳青霉杀菌效果的影响,并对处理后的壳青霉进行菌落总数测定、扫描电镜观察和紫外吸收检测,探讨超高压对茶叶中分离出的壳青霉致死效果.结果表明,处理压力和处理时间是超高压致死壳青霉的显著影响因子,且处理压力和处理时间对菌落总数的影响基本符合Logistic回归方程.500 MPa以上的压力处理10 min或者400 MPa处理12 min以上可基本杀灭壳青霉;超高压处理使壳青霉菌丝和孢子细胞壁破裂,胞内物质外溢. |

| Abstract: | The indoor experiment and field test of Marine bacterium AiL3 were carried out to study the effect on the suppression of the banana Fusarium-wilt disease and the growth of banana seedlings. The results showed that the number of leaves, the plant height, photosynthetic rate and transpiration rate of the tested banana plants were promoted significantly after innoculated with strain AiL3 in indoor and field tests compared to the control treatment. The control efficacies of AiL3 against Fusarium Wilt was 100% with the test indoor for six months. The control efficacies were 72.71% and 46.32% after 8 months with the indoor test and field test, respectively. It was suggested that the bacterial strain AiL3 could control the banana Fusarium wilt and promote growth of banana. |
