Morphological structure of dominating species of diatoms in the north-eastern Black Sea

Lifanchuk A.V.
Abstract

Influence of mineral nutrition element concentration upon the morphological structure (number of cells in the chain) and productional characteristics of leading complex of phytoplankton in the North-Eastern Black Sea in 2009-2012 was revealed. In the tests with nitrogen and phosphorus addition it was shown that increasing of the number of cells in the chain of Dactyliosolen fragilissimus (Bergon) Hasle and Sceletonema costatum (Grev.) Cleve diatoms took place under a high concentration of both mineral nutrition elements. Growing of phosphorus concentration and small content of nitrogen resulted in increasing of cellular chain of Leptocylindrus danicus Cleve and Thalassionema nitzschioides Grunow. Addition of mineral nutrition elements has not influenced on the change of cellular chain of Pseudo-nitzschia pseudodelicatissima (Hasle) Haslediatom. Experiments have shown a close interconnection between cell quantity and cell number in the chain of Th. nitzschioides, D. fragilissimus and S. costatum. For L. danicus thecorrelation between these parameters was absent, and for P. pseudodelicatissima the correlation was very weak. Intensification of growth of diatom biomass was observed when nitrogen and phosphorus were added simultaneously.

Keywords: phytoplankton, the Black Sea, nitrogen and phosphorus, length of cellular chain
