effect of gibberellic acid and benzylaadenine growth regulators on offsets production of aloe barbadensis at greenhouse conditions

the effect of gibberellic acid (ga3) and benzyladenine (ba) on aloe vera was evaluated at pot cultivation conditions. this study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. the main factor was included spraying, drip and spraying + drip. secondary factor was included concentrations of ga3 and ba at 0, 100, 200 and 400 mg.l-1 levels. the number of offset was increased by addition of ga3 and ba levels. the results show that the number of offset has been better in drip application than spraying method. the use of drip+spraying method has caused improve in the plant than other methods. the maximum offset was obtained in 400 mg.l-1 concentration of ba
