哈茨木霉β-葡聚糖酶对辣椒生长及抗青枯病的影响
Effect of β-glucanase from Trichoderma on Pepper Growth and Resistance to Bacterial Wilt Disease
摘要
Abstract
The purpose of this study is to investigate the growth promoting effect of β-glucanase from Trichoderma harzianum on pepper seedlings and its biological control effect on pepper wilt disease,in order to provide new reference directions for the biological disease control.Pepper seedlings were treated with different dilutions of β-glucanase solution,and after 30 days of transplantation,various growth indicators of peppers were detected and analyzed.Artificial inoculation of pathogenic bacteria was used to study the prevention and control effect of β-glucanase on potted pepper bacterial wilt disease.The incidence of pepper wilt disease during the seedling stage,initial flowering stage,and fruit setting stage was investigated,and the field control effect of β-glucanase on pepper wilt disease was explored.The results showed that the 10 fold solution of β-glucanase had a growth promoting rate of over 80%on the stem diameter,aboveground fresh mass,and underground fresh mass of pepper seedlings,and effectively improved the seedling strength index of pepper seedlings.The treatment of β-glucanase solution had a significant inhibitory effect on the occurrence and prevalence of pepper bacterial wilt.In the fruit setting stage of pepper,the incidence rate of β-glucanase solution treatment with different dilution ratios was 9.33%-15.00%lower than that of water control,and the control effect was 42.11%-68.22%respectively.β-glucanase from Trichoderma has a certain degree of growth promoting effect on pepper seedlings and significantly improves their resistance to bacterial wilt disease.β-glucanase has the potential to be developed into a biological agent for pepper fitness cultivation and prevention of pepper wilt disease.关键词
