Relative concentrations of Na, Ca and Mg for growth of some diatoms

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

The two types of waters, i.e., freshwater and seawater differ in their total solids (salinity), ratio of monovalent to divalent cations, the amount of the predominant cations or anions, and the Ca/Mg ratio. The growth behaviour of four diatoms isolated from these habitats was studied in different concentrations of Na, Ca and Mg which were varied taking into account the salient features of both water types. Results indicate that the growth response of these diatoms show little relationship to the composition of either fresh or seawater. It is evident that the ecological category of a species cannot be determined merely on the basis of presence or absence of its growth in certain concentrations and ratios of major ions.
