Seasonal distribution of active ectomycorrhizal roots in natural forest of Pinus roxburghii.

摘要

An experiment was conducted to estimate the distribution and activity of mycorrhizas in the roots of a Chir pine (Pinus roxburghii) forest situated behind Shimla City, Himachal Pradesh, India. Results showed that a higher number of mycorrhizal roots were recorded during rainy season. The humus layer was observed to harbour a higher number of ectomycorrhizal roots. The NPK content in the different soil layers were higher during rainy season, which was attributed to the higher number of active mycorrhizas..
