Potamogeton natans L. Growth Features in the Different Cenotic Conditions of Desna River

Abstract

Based on the value of eight dynamic metric morfoparameters and five dynamic alometrychnyh, has been given an information about growth rate of Potamogeton natans L. ramets in reservoirs of Desna River. Has been estimated the effect on the growth of Potamogeton natans plants the number of environmental factors (projective cover, the water column water transparency, the nature of the of bottom sediments). It is shown that in the area of research this plants has the vast majority of dynamic morfoparametriv in Potamogeton natans subpurum (Sviga River) and Potamogeton natans subpurum variation with Spirodela polyrrhiza and Lemna trisulca communities. The lowest rates – in Potamogeton natans subpurum (fropm a floodplain lake).
