Abstract The effect of cytokinins on the metabolic changes ’ch may take place in higher plants during the difffant phases of growth has been extensively studied during ageing. Their action on lower plants algae is still unclear. The present work describes the effect of varying concentrations of kinetin on the different growth phases of the axenic unicellular green alga Ankistrodesmus Some biochemical studies were also analysed during kinetin treatment s. rrhe work includded the analysis of cell count, optical density, protein, amino acids, soluble sugars and nucleic acids contentes. The present study appears to justify the conclusion kinetin plays a part in the retardation of the bioochanges ass ociated vvi th ageing of Ankistrodesmus It must exert a control through some fundamental The results provide evidence that kinetin stimullthe grovnh of the alga. This stimulation is high at 0.1 p MIL kinetin where protein content increased by nearly 4~.5% . |
