Abstrakt: Pinus gerardiana is a highly valuable conifer species of dry temperate, semi-arid and arid zones of the northwestern Himalayan region. The large scale harvesting of cones for nuts along with extreme weather conditions result in poor natural regeneration of this species. Thus this endemic species is facing risk of extinction in prospective times and needs special attention for conservation. In the present study, planting stock of P gerardiana was produced by artificial inoculation of Scleroderma polyrhizum and the nutrient status of rhizosphere soil and seedlings was investigated just before planting. The content of macro and micronutrients in the roots and shoots of artificially inoculated seedlings was found to be higher than in the control. The roots had higher total carbon, nitrogen and phosphorus content, whereas, the shoot samples had higher calcium, magnesium, manganese, copper and iron content. The study of corresponding seedling rhizosphere soil demonstrated a higher concentration of nutritional components in the rhizosphere soil of inoculated seedlings compared to control. Aside from that, the inoculated seedlings' rhizosphere soil was more acidic than the control. The electrical conductivity of inoculated seedlings was also higher in the rhizosphere soil. Thus the study revealed that artificial inoculation of P gerardiana with S polyrhizum enhances the nutrient absorption in the seedlings. [ABSTRACT FROM AUTHOR]
