矿质营养与其他生长物质对荷叶离褶伞菌丝生长的影响

1mg/mLKCl促进荷叶离褶伞菌丝生长;5或10mg/mLNaCl、5或10mg/mLMgSO4、5或10mg/mLKCl、10mg/mLH2PO4和1mg/mLCaSO4抑制菌丝生长;0.8mg/mL的MnSO4和CuSO4以及0.5mg/mLFeSO4、0.2或0.5mg/mLCoCl2和0.2、0.5或0.8mg/mLZnSO4促进菌丝生长;0.5或0.2mg/mLCuSO4、0.2或0.5mg/mLMnSO4及0.8或0.2mg/mLFeSO4对菌丝生长的影响不显著;维生素B6、维生素C、维生素PP和维生素B1可促进菌丝生长,在含有10μg/L维生素B6的培养基上菌丝生长速度最快,但维生素C试用浓度较低(50μg/L)时对菌丝生长的影响不显著;吲哚丁酸、吲哚乙酸、奈乙酸对菌丝生长具有促进作用,但0.1、0.5或1.0μg/L赤霉素对菌丝生长的影响不显著。

The influence of mineral nutritions and other growth substances on the growth of mycelia of Lyophyllum decastes

1mg/mL KCl, 0.8mg/mL MnSO4, 0.8mg/mL CuSO4, 0.5mg/mL FeSO4, 0.2 or 0.5mg/mL CoCl2 and 0.2, 0.5 or 0.8mg/mL ZnSO4 promote the growth of the mycelia of Lyophyllum decastes, while 5 or 10mg/mL NaCl, 5 or 10mg/mL MgSO4, 5 or 10mg/mL KCl, 10mg/mL KH2PO4 and 1mg/mL CaSO4 restrain the growth of the mycelia. 0.2 or 0.5mg/mL CuSO4, 0.2 or 0.5mg/mL MnSO4 and 0.8 or 0.2mg/mL FeSO4 have no significant influence on the growth. Vitamin B6, vitamin C, vitamin PP and vitamin B1 can improve the growth of the mycelia. In the medium containing 10μg/L vitamin B6, the mycelial growth speed is the highest. When vitamin C is lower than 50μg/L, no significant influence on the growth of mycelia is detected. Indolebutyric acid (IBA), Indoleacetic acid and naphthaleneacetic acid (NA) can promote the growth of the mycelia, but 0.1, 0.5 or 1.0μg/L gibberellin (G) have no significant impact on the growth of the mycelia.
