Abstract:
The present study was conducted to examine the impact of different concentrations of GA₃ and Ethephon on Rambutan seed germination. The experiment followed a Randomized Block Design (RBD) with three replications. The results clearly demonstrated significant differences in the effects of various concentrations of GA₃ and Ethephon on seed germination. The largest percentage of germination (60.82%) was found in seeds treated with Ethephon at a concentration of 10 ppm. Additionally, plants treated with GA₃ showed maximum plant height (24.43 cm) and a higher number of leaves (12.35). On the other hand, Ethephon-treated plants exhibited maximum root length (24.42 cm) a higher number of roots (25.46) and greater stem girth (3.50 mm).
