80种中草药对松茸T2菌株生长的影响

研究了80种中草药浸提液对培养基中松茸T2菌株生长的影响。结果表明:其中50种中草药对T2菌株生长抑制率高于10%,26种的影响较小。天葵子、白豆蔻、鱼腥草和雷公藤4种中草药对T2菌株生长有显著促进作用,增长率均高于10%,其中天葵子组T2菌株的增长率为22.55%。认为从中草药中可找到促进松茸T2菌株生长的物质,这4种中草药有效成分中都含有单萜烯类和多环二萜类物质,这些物质在松属植物中含量均十分丰富,很有可能是刺激松共生菌松茸T2菌株生长的物质。

Effects of different herbs on mycelium growth of Tricholoma matsutake T2

The effects of 80 kinds of herbs on mycelium growth of T.matsutake T_2 were investigated in this paper.The results showed that 50 kinds of herbs among them had inhibitory effect on mycelium growth with restraining rates above 10%;26 kinds of herbs had less effect;while only 4 of them(Semigaguilegia adoxoides Makino,Amomun kravanh,Houttuynia Cordata Thunb and Triterygium Wilfordii)remarkably accelerated mycelium growth with increasing rates higher than 10%.Compared with the control experiment,the highest increasing rate was 22.55%.The results indicated that the substances that stimulated mycelium growth of T.matsutake T_2 could be found in the herbs.Furthermore these herbs contain some monoterpenoids or poly-cyclic diterpenoids that are abundant in Pinus.These substances are probably the stimuli to mycelium growth of T.matsutake T_2.
