以花脸香蘑菌株“ts916”为供试菌株,采用平板培养法,在培养基中加入不同种类及质量浓度的无机盐、维生素和植物生长调节剂,研究供试物质对花脸香蘑菌丝生长的作用。结果表明,供试无机盐中,适量质量浓度的磷酸二氢钾、硫酸镁对花脸香蘑菌丝生长有促进作用,而氯化钠、氯化钾、氯化钙、硫酸锌、硫酸锰、硫酸铜抑制花脸香蘑菌丝生长。当硫酸镁质量浓度为1.5 g·L-1时,花脸香蘑菌丝生长速度最快,为4.88 mm·d-1。供试维生素(VB1、VB2、VB6、VC、叶酸和烟酸)在一定范围内均可显著促进花脸香蘑菌丝的生长,其中当VB6质量浓度为4 mg·L-1时,花脸香蘑菌丝生长速度最快,为6.63 mm·d-1。供试植物生长调节剂中,6-BA、2,4-D、NAA抑制花脸香蘑菌丝的生长,GA3的添加对花脸香蘑菌丝生长影响不显著。 相似文献

The effect of carbon and nitrogen sources, pH, temperature and substrate water content on the growth and vigor of Sparassis crispa mycelium was evaluated. Mycelial growth rates were highest when rice starch served as the carbon source and when peptone, yeast extract or soybean meal were adopted as the nitrogen source. The optimum pH and substrate water content values were 5.25 and 62.5% respectively. Mycelial growth was optimal at 20.2 ℃ and inhibited at 35 ℃, and temperatures of 40 ℃ and above killed the fungus. 相似文献
