Experimental Study of the Behavior of Aleppo Pine Seedlings in Pots Growing and Effect of Natural Litter (Monospecific and Mixed) on Growth, Biomass and Nutrient Content

摘要

A study was carried out on small Alep pine plants behaviour using vegetation pots in order to test a hypothetic litter forest effect allelopathy on this species regeneration. It revealed favourable litter action, i.e. best growth and development plant. So, it shows best monospecific Utter effect (Alep pine) on plants behaviour compared to mixed Utters (Alep pine and holm oak). This best plant behaviour which consisted of greatest radial and vertical growth, great biomass, great volumic index and bestchemical nutrition (chemical mass) was caused by the fact that Alep pine monospecific Utters, with acid character, induced best nutritious elements dynamic (N, P, K) and great microbial groups activity (mineralisators fungi, myccorhiza) in soil.
