The influence of gibberellic acid and kinetin on the growth of Scenedesmus quadricauda (Turp.) Breb.
2015
The influence of gibberellic acid (GA 3 ) and of kinetin (6-furfurylamino purine) on the increment of cell number increase in dry weight and upon protein level in Scenedesmus quadricauda (Turp.) Breb. was studied. It was found that 10 -7 M GA 3 stimulates at the same time cell growth and dry weight increase of the algae. No influence of GA 3 upon the protein content was observed. Kinetin of 10 - M concentration stimulates in the initial growth phase cell multiplication and increases the protein level. This substance promotes the increment in dry weight however in the later phase of growth. Furthermore kinetin prolongs the viability of algae, extending the growth phase.
