西澳粘滑菇在尾叶桉上的菌根合成

Mycorrhizal Synthesis of Hebeloma westraliense on Eucalyptus urophlla

利用经特殊培养的西澳粘滑菇菌种，人工接种在尾叶桉幼苗根部，３５ｄ后有６０％的幼苗根部都长出１～２个子实体，经鉴定，该子实体为原接种菌。菌根感染率检查结果表明，有８０％幼苗形成菌根。生长８个月的幼苗其平均树高比未接种苗增加５２．２％，地径增加２９．４％，地上及地下部分生物量（干重）分别比对照增加２６８％及２１４．３％。西澳粘滑菇不仅在华南地区桉树上可以完成菌根合成，而且对幼树生长的增产效果十分明显，是华南地区桉树的优良菌根菌。

days after the inoculation with pure culture of Hebeloma westraliense,amycorrhizal fungus,to young seedlings of E. urophylla ,some mycorrhizal root and alsosome fruit- bodies of the fungus were produced. Successful inoculation rate were 80%,and60%of the inoculated seedlings produced fruit- bodies. The inoculated seedlings developedbetter root system ,greener leaves and better growth than those of the non- inoculatedseedlings. The height,ground diameter,above-ground and under-ground biomass of the 8-month-old inoculated seedlings were increased by 52.2%,29.4%,268.0%and 214.3%than those of the non-inoculated seedlings respectively.
