树木菌根真菌——美味红菇复合制剂的生物效应*

在探明菌根真菌美味红菇生理活性物质的基础上,为使其实用化,又从该菌的发酵液中提取并研制成真菌复合制剂。除在医学上进行了一系列抗菌活性试验外,同时还在育苗造林上,利用不同树种进行防病保苗促进生长的生物活性试验。本文主要报道应用美味红菇复合制剂对几种亚热带针阔叶树种幼苗和种子进行体内生物活性的试验结果。目的在于观察和研究该复合制剂对促进幼苗生长和提高抗生能力的生物效应,以便进一步开拓美味红菇复合制剂的有效应用范围和途径。

A STUDY ON BIOLOGICAL EFFECTS OF RUSSULA DELICA COMPLEX PREPARATION

Russula delica complex preparation consists of several phisiological active substances from the liquid fermentation extract of Russula delica. The physio-chemical properties and spectral analyses (UV, IR, NMR, MS, HPLC) show that these substances are antibiocitic 82-101A (10-20 mg/ml), antibiotic B (5-10mg/ml), and endogenous hormones of Z(2.6mg/ml), GA3(7.4mg/ml), ABA(0.2 mg/ml) and KT(0.3 mg/ml). Indoor and outdoor biological activity test of dilutions of the complex preparation 1:50 and 1:100 on Pinus massoniana Lamb, Pinus taiwanensis Hayata and Pterocarya stenoptera DC. show that the preparation has biological effects of raising physiological activity of seedlings, promoting the growth and increasing antibiotic ability of them.
