Interactive effects of salinity with some hormonal and non hormonal growth substances on chlorella fusca I- biomass and photosynthetic pigments

ABSTRACT

The response of Chlorella fusca to different salinization treatment was followed. Dry weight and pigment concentrations were stimulated with salinization up to the levels of 80 mM NaCl, beyond which they were retarded. Also, growth and pigment contents were stimulated at 10-6, 10-5 M concentrations of IAA, kinetin, GA3 and thiourea relevant to control. These chemicals counterated the adverse effect of salinity on Chlorella cells. IAA was the most effective substance followed by kinetin, GA3 and thiourea
