Assessment of GA3and BA application on gerbera cultivation in soilless culture

Abstract

This research was carried out to determine the effect of gibberellic acid (GA ) and benzyladenine (BA) application on 3yield and quality components (multiplication ratio, flower stem length, flower diameter, vase life, flower stem diameter,)of gerbera. Three different levels of GA (125, 250, 500 ppm) and BA (100, 200, 400 ppm) were applied by foliar spray. 3Compared to BA application, GA applications gave good results on yield and quality parameters. The maximum yield 3was obtained by 125 ppm of GA application. It was found that 500 ppm of GA application most effective on stem length 3 3and flower diameter. On the other hand, it's determined that 400 ppm BA application significantly increased stemdiameter and multiplication ratio. Its concluded that, the GA and BA demonstration interference in growth 3characteristics of gerbera plant.
