Abstract
Effects of medium,temperature,pH value and nutritional factors on the mycelium growth,spore yield and spore germination rate of Botrytis cinerea were conducted with the strain B05.10 as experimental material.The results showed that spore yield of the strain reached 1500 ×104 cfu/plate on the PSA medium,pH 6.0 and 22℃ for 7 d.When cultured for 4 hours at the condition of 1% agar,pH 5.0 and 22℃,conidia of B.cinerea appeared germ tube,and it changed to branch mycelium for 12 h.These nutritional factors including xylose,fructose and soluble starch had obvious promotion to spore germination rate of the strain B05.10.
