Abstract: | Castanopsis fissa Rehd. & Wils. is widely distributed from the tropics to the temperate regions of China and Japan and is an important forest component in Hong Kong. Pot-grown C. fissa seedlings inoculated with vegetative mycelial inocula of seven ectomycorrhizal fungi for 20 weeks were analysed for growth performance and mineral nutrient uptake of N, P, K and Ca. Shoot growth stimulation in all fungal treatments generally occurred in the first 4–8 weeks of seedling development. Uptake of P was generally enhanced by all fungi inoculated. Seedlings inoculated with Pisolithus tinctorius (Pers.) Coker and Couch and Cenococcum geophilm (Sow.) Fredinard et Winge, which colonized 22% and 33% of roots respectively, exhibited growth stimulation. The results indicate that P. tinctorius and C. geophilum are suitable for use in large-scale nursey inoculation. |
