Effects of Ectomycorrhizal Fungi on Growth of Seedlings of Pinus densiflora

Abstract

This study was conducted to investigate the different effects of cetomycorrhizal fungal (ECMF) species on the growth of seedlings of Pinus densiflora, and the effects of ECMF diversity on plant productivity. A total of live species of ECMF were isolated from root tips of pine seedlings collected from Mt. Songni and used as inocula. Pots containing pine seedlings were inoculated with either a single ECMF species or a mixture of live ECMF species. All of the seedlings formed ECM on their roots except for the control plants. The pine seedlings’ growth responses varied by the different ECMF species. Also, pine seedlings inoculated with a mixture of live ECMF species showed the highest growth response. The results of the study suggest that the colonization of diverse species of ECMF will increase plant productivity, and the selection of suitable ECMF species could be an important factor for plant growth.
