The Effect of Gibberellic Acid on Reducing Sugar of Jerusalem Cherry (Solanum pseudocapsicum L.) Plant

The effect of Gibberellic Acid (GA3) on Jerusalem cherry (Solanum pseudocapsicum L.) was evaluated at pot cultivation conditions. This study was performed in factorial test based on complete random design plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 at 0, 100, 200 and 400 mg.L -1 levels. Result showed that GA3 concentration and its usage methods had significant effect on (P <0.05) reducing sugars content. By increasing in concentration, reducing sugar decreased at three methods respect to control. Drip method with 100 mg.L -1 contained the highest amount of reducing sugars, whereas spraying + drip method with 100 mg.L -1 had the least amount of reducing sugars. In this study, plants to drip method increased the amount of reducing-sugars compared to the spray + drip method. Also, both method of spray and drip Compared with in spray + drip method increased reducing-sugars. The highest content of reducing-sugars obtained with application of 100 mg. L -1 With drip method was 27.20% higher compared to the control treatment.
