不同甜菜尾孢菌对生长环境因子的响应研究
Study on Responses of Different Cercospora beticola Strains to Environmental Factors for Growth
摘要
Abstract
[Objective]To study the responses of different Cercospora beticola strains to environmental factors for growth and lay a theoretical foundation for the control of Cercospora leaf spot,[Methods]nine Cercospora beticola strains were isolated from different sugar beet plant areas and cultured on different culture media,light,temperature and pH conditions.[Results]The growth rates of all Cercospora beticola strains on potato dextrose agar and sabaurauds agar media were significantly higher than those on oatmeal agar and malt extract agar media.All nine strains of Cercospora beticola exhibited faster growth rates under alternating light-dark or full-light conditions.The optimal temperature for growth of the nine strains was 20℃to 30℃,while the most suitable pH range for growth was between 5 to 7,with alkaline conditions significantly inhibiting the growth of most strains.Except for strains HLC20-1,HHC20-1 and WC20-1,the other strains exhibited a high conidium producing capacity on different culture media.[Conclusion]Cercospora beticola isolates from different sugar beet plant areas showed differential responses to environmental factors during growth.When conducting research on sugar beet disease control,it is necessary to rationally select the culture conditions of Cercospora beticola.关键词
