【Abstract】 The mycorrhization of twelve mycorrhizal strains from Europe and Taiwan together with seedlings of Pinus massoniana Lamb. from Fujian was examined under vit ro-conditions. Among these strains Pisolithus tinctorius, originating from Taiwan, proved to be of easy mycorrhization, fast growing and insensitive to un favorable environmental conditions. The results of analysis of Pisolithus tinc torius-Pinus massoniana mycorrhizae by electron energy-loss spectroscopy(EEL S) showed this strain displayed a higher frequency of active hyphal sheaths and a high er potential to store nitrogen and phosphorus than other mycorrhizal types. Phos phorus and nitrogen were localized in vacuolar bodies.P. tinctorius was found to be more efficient in storing the macronutrient P and N.更多还原
