姜油对番茄致病菌的抑制效果及抑菌机制初探
目的 研究姜油对番茄致病菌的抑制效果及抑菌机制。方法 通过体外抑菌试验检测姜油对番茄早疫病菌、番茄灰霉病菌、番茄疮痂病菌3种番茄致病菌的抗菌性及其抗菌强度, 通过体内试验验证姜油对番茄致病菌的抑制效果; 并通过测定菌体湿重、细胞膜通透性初步探讨姜油抑菌机制。结果 姜油对3种番茄致病菌均有一定的抑制作用; 体内试验研究发现采用熏蒸方式处理的番茄其腐烂率低于直接接触的方式; 姜油能抑制3种番茄致病菌菌体湿重的增加, 增大菌体培养液电导率。结论 姜油可能通过抑制菌丝体正常的生长和繁殖和破坏菌体细胞膜来达到抑菌效果。
Objective To investigate the inhibitory effect and antibacterial mechanism of ginger oil on tomato pathogens. Methods The antimicrobial effects of ginger oil against three kinds of pathogenic bacteria and fungus on tomatoes including Alternaria solani, Botrytis cinerea and tomato Fusarium were detected in vitro and verified in vivo. And also the inhibition mechanism of ginger oil against three kinds of pathogenic bacteria and fungus on tomatoes was investigated by detection of the cell wet weights and the permeability of cell membranes. Results Ginger oil had good antimicrobial effects against three kinds of pathogenic bacteria and fungus. In vivo tests showed that the decay rate by fumigation treatment was significantly lower than that of direct contact. The inhibition mechanism study showed that the ginger oil could inhibit the increase of cell wet weight and increase the conductivity of nutrient solution. Conclusion The antibacterial effect of ginger oil may be caused by inhibiting the growth and reproduction of mycelium and destroying the cell membrane.
