外生菌根菌接种马尾松和相思树幼苗的研究

以外生菌根菌Ｘｅｒｏｃｏｍｕｓｃｈｒｙｓｅｎｔｅｒｏｎ接种相思树与马尾松幼苗，不灭菌栽培，植株生长指标和生理特性测定，都优于对照．以外生菌根菌Ｃａｌｖａｔｉａｌｉｌａｃｉｎａ加ＶＡ菌根菌Ｇｌｏｍｕｓｓｐｉｇａｎｕｓ双接种于相思树幼苗，灭菌栽培．植株含Ｎ量和脯氨酸等含量优于ＶＡ菌根菌单接种的效果．幼根切片观察到接种的外生菌根菌进入根皮层细胞间隙，原有菌根的发育和结构状况有所改变．

Effect of inoculating ectomycorrbizal fungus on Acacia confusa and Pinus massoniuna seedlings.

Seedlings of Acacia confusa and Pinus massoniana inoculated with ectomycorrhizal fungusXerocomus chrysenteron under non-sterilized condition have a better growth than control.When Acacia confusa seedlings are inoculated with ectomycorrhizal fungus Calvatialilacina and VA mycorrhizal fungus Glomus epigamus under sterilized condition, their nitrogen and proline contents are higher than those treated with G. epigamus alone. Observations on young infected root sections show that ectomycorrhizal fungus hyphae can penetrate into intercellular space, and the development and structure of mycorrhizae are improved.
