N2 - The effects of the interaction between Suillus luteus (L.) Roussel and Trichoderma virens (J.H. Mill., Giddens & A.A. Foster) Arx on Pinus sylvestris var. mongolica Litv. were studied using plant physiology, mycorrhizal science, forest pathology, and biochemistry. Seedling growth and physiological parameters were determined, including the colonization rate of mycorrhizal fungi, biomass, root activity, photosynthetic pigment content, soluble protein content, antioxidant enzyme activities, rhizosphere soil enzyme activities, and protective enzyme activities. In addition, an optimal resistance system involving T. virens, mycorrhizal fungus (S. luteus), and P. sylvestris var. mongolica seedlings was constructed. Synergies between S. luteus and T. virens were observed, and most of the parameters of P. sylvestris var. mongolica seedlings inoculated with S. luteus 30 days + T. virens were higher than other treatments. After three months, when compared the control, the S. luteus 30 days + T. virens treatment gave increases in height (42.3 %); collar diameter (66.7 %); fresh weight (54 %); dry weight (50 %); soluble protein content (69.86 %); root activity (150 %); chlorophyll a (77.6 %); chlorophyll b (70.5 %); carotenoids (144 %); CAT activity (876.9 %); POD activity (268.3 %); SOD activity (66.18 %); β-1,3-glucanase activity (125.8 %); chitinase activity (40 %); rhizosphere soil catalase activity (97.8 %); and phosphatase activity (266.7 %). These results indicate that there may be a stimulating factor between S. luteus and T. virens when they are inoculated together (S. luteus 30 days + T. virens).
