Abstract
The methods of germination enhancement of ‘Khaek Dam Kaset’ papaya seed to enhance the germination and seed vigor were studied. Seeds were soaked in reverse osmosis (RO) water, gibberellic acid (GA3) solution and salicylic acid (SA) solution in different concentrations for 16 hours. The experiment was designed in a completely randomized design composed of 7 treatments: RO water, 500 mg/L GA3 solution and SA solution at 50, 100, 250 and 500 mg/L compared with the untreated seed (control). The results showed that soaked seeds in 500 mg/L GA3 solution had no effect on germination when compared with control, but these treatments had faster mean germination time (MGT) than control (approximately 1 day). Moreover, soaked seeds in all concentrations of SA solution did not affect on germination, when compared with control.
