| Abstract: | Objective]The aim was to research the basic biological characteristics of 11 strains of blight germs in hybrid bamboo.Method] With 11 strains of blight germs isolated from hybrid bamboo from bamboo forest base with severe blight of Guangxi Huajin Bamboo Forest Development ltd.as material,the most suitable conditions for their growth and spore germination were confirmed and their lethal temperature was determined.Result]The most suitable growth media and illumination conditions for 11 strains were different,their most suitable growth temperature and pH value,optimum carbon source and nitrogen source were 24-28 ℃,7.0-11.0,lactose and sorbitol,and yeast extract resp.The most suitable temperature for conidium germination was around 24-30 ℃,the optimum carbon sources were maltose,lactose and sucrose,the optimum nitrogen sources were yeast extract and beef extract.Its lethal temperature was 50 ℃(10 min).Conclusion]This research laid a good theoretical foundation for controlling blight in hybrid bamboo. |
