Field experiment was conducted in Dubrava nursery during 2000-2001 to investigate the effect of separate nursery substrata (pine and oak stand litter and decomposed peat) on mycorrhizal development and to evaluate the variability of mycorrhizal morphotypes and seedling growth parameters of different Scots pine (Pinus sylvestris) populations. Scots pine seedlings were collected from different regions, viz., Telsiai, Labanoras and Veiseijai. The total amount of mycorrhiza in the control ground without litter is 9, 15 and 16% higher than in oak and pine stand litter, and decomposed peat, respectively. The variability of the most common (ectendomycorrhiza and ectomycorrhiza) mycorrhizas were determined in the nursery substrata. While ectendomycorrhiza dominates (60%) in decomposed peat, the occurrence of ectomycorrhiza decreases (12%). In oak stand litter, ectomycorrhiza increased (28%) with respect to ectendomycorrhiza and dead mycorrhiza. Concerning population level, the outspread of ectomycorrhiza in respect to other morphotypes of Labanoras population (19%) surpassed the representatives of Veisiejai (14%) and Telsiai (12%) populations. The reaction of mycorrhiza morphotypes highlighted higher sensitivities of Telsiai population, which influence weaker growth of seedlings. The diversity of mycorrhizal fungi presupposes selection possibilities of seedlings according to its types and ensures more rapid growth and greater resistance of seedlings to various environmental factors.. |
