Abstract: The impact of various applications of gibberellic acid (GA3) was studied on potato varieties at the rate of 1 mg/l, 1.5 mg/l and 2 mg/l especially for the Lady Rosette cultivar. The objective of this study was to investigate the effect of gibberellic acid (GA3) on different growth parameters of potato plants such as no. of plantlets, total no. of stems and total number of leaves. This research was conducted at the Biotechnology Laboratory, Department of Agriculture Research, Gilgit Baltistan to culture potato seedlings. Thirty beakers were used under various treatments and different growth and developmental parameters were examined i.e., number of plantlets, total number of stems and total number of leaves. The findings showed significant differences (p > 0.05) in growth among the different concentrations of gibberellic acid throughout the study period. Based on the results, the treatment with 1 mg/l gibberellic acid was found to be the most effective for leaf propagation in potato. Conversely, the treatment with 2 mg/l gibberellic acid showed the lowest values for the mentioned parameters. Lady Rosetta exhibited the highest number of leaves with good strength, recording 36 leaves, followed by 1 mg/l with 32 leaves, and 1.5 mg/l with 31 leaves. Overall, this research provides valuable insights into the optimization of potato plant propagation, specifically leaf production. The future applications include commercial potato cultivation, seed potato production, potato breeding programs, controlled environment agriculture, and further academic research in the field. © 2022 The Author(s)
