外生菌根真菌对薄壳山核桃幼苗生长的影响

Effects of Ectomycorrhizal Fungi on Seedling Growth of Carya illinoinensis

本研究以薄壳山核桃波尼实生苗为试验对象,采用完全随机盆栽试验设计,探讨外生菌根真菌接种对薄壳山核桃幼苗生长的影响。结果表明:相比对照苗,外生菌根真菌接种可显著提高薄壳山核桃幼苗的地上干重和叶片光合能力(P<0.05)。其中,接种土生空团菌幼苗的地径和根系生物量显著高于对照苗和豆马勃属接种苗。

Taking the seedlings of pecan cultivar ′ Pawnee′ as the experimental object and using a completely random pot experiment design, this paper studied the effects of ectomycorrhizal fungi inoculation on seedling growth of Carya illinoinensis. The results showed that compared with the control seedlings, ectomycorrhizal fungi inoculation could significantly improve the aboveground dry weight and leaf photosynthetic capacity of Carya illinoinensis seedlings(P<0.05). Among them, the ground diameter and root biomass of the seedlings inoculated with Cenococcum geophilum were significantly higher than those of the control seedlings and the seedlings inoculated with Pisolithus sp.
