To assess dual-mycorrhizal colonization in subtropical forests, we sampled the roots of 181 trees from 38 species within a 25 hm2 subtropical forest plot in the Fengyangshan-Baishanzu National Nature Reserve. We examined mycorrhizal status and measured the mycorrhizal colonization rate under a microscope, and analyzed the characteristic of dual-mycorrhizal colonization. Among the 38 species, 29 and 3 species were characterized by arbuscular mycorrhizal ( AM ) or ectomycorrhizal ( EcM), respectively, whereas the remaining 6 species formed dual-mycorrhizal associations. These dual-mycorrhizal tree species ( Lithocarpus brevicarantus, Lithocarpus hancei, Castanopsis eyrie, Quercus engleriana, Fagus lucida, and Pinus taiwanensis) belong to the families Fagaceae and Pinaceae. Among these species, the diameters at breast height ( DBH) of dual-mycorrhizal individuals were significantly smaller than those of individuals without dual-mycorrhizal colonization. For these dual-mycorrhizal individuals, EcM and AM fungal colonization was found to be negatively correlated, with EcM and AM colonization increasing and decreasing with increasing DBH, respectively. In conclusion, dual-mycorrhizal colonization may occur in some tree species that have previously been categorized as EcM plants and generally takes place at the juvenile stage. Moreover, the predominant mycorrhizal type of these dual-mycorrhizal species shifts from AM to EcM with the continued growth of plant individuals. [ABSTRACT FROM AUTHOR]

This study aims to investigate the adaptation mechanism of mycorrhizal Pinus massoniana seedlings to aluminum ( Al3+ ), and to provide a theoretical and technical basis for alleviating aluminum toxicity in P. massoniana seedlings. The effect of mycorrhiza on growth and nutrient absorption in P. massoniana seedlings was investigated by comparing uninoculated seedlings ( control) with seedlings inoculated wdth Suillus luteus (SL), subjected to one of five different Al3+ concentrations (0, 0.2, 0.4, 0. 8 and 1.2 minol^L 1) grown in a hydroponic system. Results showed inoculated seedlings, when compared to uninoculated seedlings grown in equivalent Al3+ concentrations, demonstrated increased growth in plant height, biomass, and root morphology, as well as an increased capacity to absorb N, P and K. For both inoculated and uninoculated P. massoniana seedlings; the height of the plant, accumulation of dry matter mass, and root growth, showed a fluctuating trend of first rising, then falling, then further rising with increased concentrations of Al3+. In addition, for both inoculated and uninoculated seedlings, the gradual increase of Al3+ concentration of N, P and K content in roots, stems, and leaves demonstrated a tendency toward low concentration thus promoting high concentration inhibition ( the order of Al3+ content measured in three plant organs, ordered from high to low, was root>stem>leaf). The results of our study suggest that P. massoniana seedlings inoculated with SL under Al3+ stress appear to be able to promote the absorption of nutrients ( such as N, P and K) and inhibit absorption of Al3+ in mycorrhizal P. massoniana seedlings by changing the structure of the root.
