Interactive effects of salinity with some hormonal and non-hormonal growth substances on chlorella fusca II- nitrate reductase activity, proline and protein contents

ABSTRACT

Sodium chloride at 320 mM increased proline content but suppressed protein accumulation and nitrate reductase activity of Chlorella fusca. 10-5 M, 10-6 M of GA3, IAA, kinetin and thiourea increased protein, proline and NRA of the algal cells relevant to control. The four used growth substances reacted in antagonism with NaCl in the same parameters. In counteracting, the adverse effect of salinity, IAA was more effective, while thiourea was the least effective one
