[Method] 11 F. oxysporum strains of hybrid bamboo were isolated from diseased bamboo tissue in the bamboo base of Guangxi Huajing Bamboo Development Co., Ltd.. Biological characteristics of these pathogens were studied. [ Result] The optimum growth medium and light conditions for 11 strains were different, the optimum growth temperature was 24 -28 ℃, the optimum pH value was 7.0 - 11.0, lactose and D-sorbitol were the best carbon sources, and yeast extract was the best nitrogen source. The optimum temperature for oonidia germination was about 24 -30 ℃3, the best carbon source were maltose, lactose and sucrose, the best nitrogen source was yeast extract and beef extract. The lethal temperature of conidia was 50 ℃ （10 min）. [ Cendusioal The study supplied good theoretical basis for the control of Fusarium wilt disease in hybdd bamboo.展开更多
