维生素及生长调节剂对黑牛肝菌菌丝生长的影响

Effects of Vitamin and Growth Regulator on the Mycelial Growth of Phlebopus portentosus

在黑牛肝菌母种培养基中分别添加浓度为0.05 g·L^(-1)、0.10 g·L^(-1)、0.50 g·L^(-1)的维生素B_(1)、维生素B_(2)、烟酸、烟酰胺、维生素B_6、维生素C及生长调节剂吲哚-3-乙酸、6-苄氨基腺嘌呤,探讨其对黑牛肝菌菌丝生长的影响。结果表明,除IAA外的添加剂对黑牛肝菌菌丝生长速度、菌丝长势、菌落颜色、吐水情况、菌落的边缘整齐度均有一定的促进作用。其中,添加0.05 g·L^(-1)的VB1和0.50 g·L^(-1)的VC后,菌丝生长速度和菌落形态明显优于其他维生素和生长调节剂。所有试验浓度的IAA均对菌丝生长有抑制作用。

VB_(1),VB_(2),niacin,nicotinamide,VB6,VC,growth regulators IAA and 6-BA with concentrations of 0.05 g·L^(-1),0.10 g·L^(-1) or 0.50 g·L^(-1) were added to culture medium to investigate their effects on mycelial growth of Phlebopus portentosus.The results showed that except for IAA,these additives all had promoting effects on mycelial growth rate,growth vigor,colony color,exudation,and colony neatness of P.portentosus.Among which,VB1 at 0.05 g·L^(-1) and VC at 0.5 g·L^(-1) showed significant promotion than other additives.IAA inhibited mycelial growth of P.portentosus at all experimental concentrations.
