| effects of litter addition on ectomycorrhizal associates of a lodgepole pine (pinus contorta) stand in yellowstone national park. | increasing soil nutrients through litter manipulation, pollution, or fertilization can adversely affect ectomycorrhizal (em) communities by inhibiting fungal growth. in this study, we used molecular genetic methods to determine the effects of litter addition on the em community of a pinus contorta stand in yellowstone national park that regenerated after a stand-replacing fire. two controls were used; in unmodified control plots nothing was added to the soil, and in perlite plots perlite, a chem ... | 2003 | 12839743 |
| genetic diversity of naturally established ectomycorrhizal fungi on norway spruce seedlings under nursery conditions. | we have assessed ectomycorrhizal fungi colonizing norway spruce (picea abies l.) seedlings in nine forest nurseries using restriction fragment length polymorphism (rflp) and sequencing analyses of the internal transcribed spacers (its1-5.8s-its2) amplicons. restriction analysis of the amplified dna fragments with hinfi, mboi, and taqi enzymes allowed the definition of 17 rflp genotypes; five of them could be unambiguously assigned to thelephora terrestris, hebeloma longicaudum, h. crustuliniform ... | 2006 | 16826321 |
| growth and mycorrhizal community structure of pinus sylvestris seedlings following the addition of forest litter. | we report the effects of pine and oak litter on species composition and diversity of mycorrhizal fungi colonizing 2-year-old pinus sylvestris l. seedlings grown in a bare-root nursery in lithuania. a layer of pine or oak litter was placed on the surface of the nursery bed soil to mimic natural litter cover. oak litter amendment appeared to be most favorable for seedling survival, with a 73% survival rate, in contrast to the untreated mineral bed soil (44%). the concentrations of total n, p, k, c ... | 2007 | 17575001 |
| root hydraulic properties and growth of balsam poplar (populus balsamifera) mycorrhizal with hebeloma crustuliniforme and wilcoxina mikolae var. mikolae. | the effects of an e-strain fungus (wilcoxina mikolae var. mikolae) and an ectomycorrhizal fungus (hebeloma crustuliniforme) on growth and water relations of balsam poplar were examined and compared in the present study. balsam poplar roots inoculated with w. mikolae var. mikolae (wm) exhibited structures consistent with ectendomycorrhizal (eem) associations, including a mantle surrounding the outside of the root and an extensive hartig net that was located between cortical cells and extended to ... | 2008 | 18685871 |
| ectomycorrhizal species associated with pinus radiata in new zealand including novel associations determined by molecular analysis. | ectomycorrhizal (ecm) associates of the exotic plantation species pinus radiata were investigated above and below ground over two years in the north island of new zealand. ecm species were identified using morphological and molecular (restriction fragment length polymorphism and dna sequencing) analysis. eighteen ecm species were observed fruiting above ground; 19 ecm species were identified below ground. in the above ground study, wilcoxina mikolae, rhizopogon pseudoroseolus and inocybe sindoni ... | 2010 | 19756777 |
| ectomycorrhizal community structure of different genotypes of scots pine under forest nursery conditions. | in this paper, we report the effect of scots pine genotypes on ectomycorrhizal (ecm) community and growth, survival, and foliar nutrient composition of 2-year-old seedlings grown in forest bare-root nursery conditions in lithuania. the scots pine seeds originated from five stands from latvia (p1), lithuania (p2 and p3), belarus (p4), and poland (p5). based on molecular identification, seven ecm fungal taxa were identified: suillus luteus and suillus variegatus (within the suilloid type), wilcoxi ... | 2010 | 20155377 |
| ericaceous dwarf shrubs affect ectomycorrhizal fungal community of the invasive pinus strobus and native pinus sylvestris in a pot experiment. | this study aimed to elucidate the relationship between ericaceous understorey shrubs and the diversity and abundance of ectomycorrhizal fungi (ecmf) associated with the invasive pinus strobus and native pinus sylvestris. seedlings of both pines were grown in mesocosms and subjected to three treatments simulating different forest microhabitats: (a) grown in isolation and grown with (b) vaccinium myrtillus or (c) vaccinium vitis-idaea. ericaceous plants did not act as a species pool of pine mycobi ... | 2010 | 21161550 |
