摘　　要：【目的】探讨不同种类无机盐、维生素、植物生长调节剂对朱红硫磺菌菌丝生长的影响。【方法】以朱红硫磺菌菌株LS-1为研究对象,以该菌株菌丝生长速率为指标,研究不同质量浓度的无机盐、维生素及植物生长调节剂对朱红硫磺菌菌丝生长的影响。【结果】不同种类无机盐中,硫酸镁、磷酸二氢钾、氯化钠、氯化钾对朱红硫磺菌菌丝生长均有一定的促进作用,而氯化钙对菌丝生长有抑制作用。当硫酸镁、磷酸二氢钾质量浓度为1.0 g/L时,菌丝生长速率最大,分别为2.536 mm/d、2.464 mm/d;不同种类维生素中,维生素B2、B4、B6在供试范围内对菌丝生长促进作用较强,其中在含有10 mg/L维生素B4的培养基上菌丝生长最快;供试的植物生长调节剂中,6-糠氨基嘌呤(6-KT)对菌丝生长的促进作用较强,其次为6-苄氨基嘌呤(6-BA),而吲哚乙酸(IAA)、萘乙酸(NAA)对朱红硫磺菌菌丝生长有抑制作用。【结论】在培养基中,添加适宜浓度的硫酸镁、维生素B4和6-BA可促进朱红硫磺菌菌丝生长。[Objective] In order to investigate the effects of inorganic salts, vitamins and phytohomones on the growth of Laetiporus sulphureus. [Method] Laetiporus sulphureus strain LS-1 was used as testing material and the mycelial growth was measured as index. Inorganic salts, vitamins and phytohomones were measured to obtain the effect of the mycelial growth on Laetiporus sulphureus. [Results] For different inorganic salts, magnesium sulphate, potassium dihydrogen phosphate, sodium chloride, potassium chloride can promote mycelial growth of Laetiporus sulphureus, however, mycelial growth was inhibited by calcium chloride. When magnesium sulfate and monopotassium phosphate were 1.0 g/L, the mycelial growth reached maximal value （2.536 mm/d and 2.464 mm/d）. Different types of vitamins VB2, VB4, VB6 had powerful enhancement on the mycelial growth of Laetiporus sulphureus. The mycelial growth reach a peak value result revealed as the concentration of VB4 was 10 mg/L. For different types of phytohomones, 6-KT can remarkably promote the mycelial growth of Laetiporus sulphureus followed by 6-BA. However, IAA and NAA had inhibition on the mycelial growth of Laetuoorus sulphureus. [Conclusion] The results showed that different concentration of inorganic salts, vitamins and phytohomones had a great effect on the growth of Laetiporus sulphureus.
