Russian Journal of Ecology - Abstract—The study of the effect of mycorrhiza symbiosis on the transformation of carbon and nitrogen compounds in soils is important in view of the necessity to...     

Seed reproduction traits of alpine plants depend on soil enrichment

Changes in parameters of seed reproduction in response to 15-year application of mineral nutrients in different variants (N, P, NP, Ca) and irrigation (variant Н₂О) were studied in 12 alpine plant species from four communities of the Northwestern Caucasus. No increase in seed production, compared to control, was revealed in any of the species. The number of generative shoots was found to decrease in the majority of species, increasing only in Leontodon hispidus in Р and in Festuca varia in NP treatment. Seed harvest increased significantly in four species—Festuca varia (Ca, P, N, NP treatments), Leontodon hispidus (H₂O, Ca, P), Geranium gymnocaulon (Ca, P, NP), and Sibbaldia procumbens (P)—and decreased in seven species.
