| 摘 要： | 菌根食用菌（edible mycorrhizal fungi,EMF）是兼具生态价值和经济价值的大型真菌,其对林木健康、森林生态系统的稳定性及林下经济的发展至关重要。本研究以贵州地区马尾松Pinus massoniana林2种乳牛肝菌属Suillus EMF为研究对象,研究了其子实体及其与马尾松形成的菌根的形态特征,调查了其子实体的发生规律及其与温度和降雨的关系。研究结果表明：粘盖乳牛肝菌S. bovinus和褐环乳牛肝菌S. luteus可同时在马尾松林发生。粘盖乳牛肝菌和褐环乳牛肝菌与马尾松形成的菌根均呈珊瑚状,其中粘盖乳牛肝菌形成的菌根表面光滑无根外菌丝但具有根外菌索,褐环乳牛肝菌形成的菌根具有密集的根外菌丝但无根外菌索。粘盖乳牛肝菌和褐环乳牛肝菌子实体具有较长的发生期、产量较大,且具有错峰发生的特点。相对于降雨,温度是这2种乳牛肝菌子实体发生的主要限制因素。

| Abstract: | Edible mycorrhizal fungi (EMF) are valuable forest resources, in terms of their ecological functions as symbiont of forest trees and the economic value of their edible basidiomata. They are supposed to play important roles in sustaining forest tree and ecosystem health, and contributing to economic development. In this study, basidiomata and mycorrhizas of two Suillus species associated with Pinus massoniana were morphologically observed, and a three-year field survey was conducted to clarify the phenology of the formation of basidiomata. It was proved that S. bovinus and S. luteus coexisted in forest of P. massoniana in Guizhou Province. The ectomycorrhizas of the two fungi formed in P. massoniana roots are usually coralloid in shape with dichotomous branches. The mycorrhizas formed by S. bovinus had smooth surface without emanating hyphae but with rhizomorph, while those formed by S. luteus had densely emanating hyphae but had no rhizomorph. The basidiomata formed by the two fungi have long fruiting season, considerable production, and staggered occurrence of fruiting peak. Compared with the precipitation, the temperature seemed to be more important in determining basidioma production. |
