Influence of Pisolithus Tinctorius Inoculation on Greenhouse Growth and First-Year Transplant Survival of Conifer Seedlings.

摘要

Mycorrhizal fungi form a symbiotic association with the root systems of most higher plants. Mycorrhizae colonization of root systems is believed to improve tolerance to adverse soil conditions such as low pH or high salinity. Mined land reclamation may require transplanting seedlings onto harsh sites that may have low pHs, high salinity, low nutrient status, etc. The purpose of this study was to examine whether inoculation of conifer seedlings in the greenhouse with Pisolithus tinctorius would improve first year survival of seedlings transplanted onto overburden material at the Molycorp Questa Mine in northern New Mexico. Seedlings of Pinus ponderosa, P. edulis, P. strobiformis, P. flexilis, P. aristata, P. sylvestris, and P. nigra were used in this study.
