Abstract

This study aimed to evaluate and analyze the effect of priming using GA3 on the growth of various shallot varieties from seeds. This pot study was conducted at Exfarm, Faculty of Agriculture, Hasanuddin University from July to September 2022. The research was arranged in factorial with a randomized complete block design (RCBD) with two treatment factors. The first factor was seed priming consisting of control or no priming (S0), priming with water (S1), 25 mg L -1 GA3 (S2), 50 mg L -1 GA3 (S3) and 75 mg L -1 GA3 (S4). The second factor is the variety consisting of Tuk-Tuk (v1), Sanren F1 (v2), Lokananta (v3), and Maserati (v4). Seed performance testing is carried out by planting prime seeds in pots. Meanwhile, parameters observed included six agronomic parameters and three chlorophyll parameters. The results show that priming with GA3 at concentration of 75 mg L -1 significantly influence the plant height, number of leaves, fresh weight, chlorophyll b content, and total chlorophyll. Variety treatments recorded different responses to various parameters. The Lokananta variety recorded the highest average plant height and dry seedling weight. The Maserati variety recorded the largest average diameter of pseudo stems. Meanwhile, the interaction between GA3 at 75 mg L -1 and the Maserati variety has a significant effect on the root length of shallot seedlings. Then, the interaction between Tuk-Tuk varieties and GA3 75 mg L -1 priming gave the best effect on chlorophyll content.
