Description
This research paper delves into the influence of plant growth regulators (PGRs) on the germination percentage of four distinct plant species, specifically Albizia lebbeck (L.) Benth., Holoptelea integrifolia (Roxb.) Planch., Acacia catechu (L.f.) Willd., and Terminalia bellirica (Gaertn.) Roxb. The study was conducted at Arid Forest Research Institute, Jodhpur, during the summer of 2022. The study employed three PGRs: gibberellic acid (GA3), indole acetic acid (IAA), and indole-3-butyric acid (IBA) at two concentrations of 500 ppm and 1000 ppm. The primary objectives of this study were to evaluate the germination percentage of the four plant species and to ascertain the optimal PGR treatment for seed germination. The results of this research could potentially aid in the development of effective strategies to enhance seed germination and overall plant growth. The study revealed that the impact of PGRs on germination percentage was dependent on the plant species and the concentration of the PGR used. The findings indicated that the use of PGRs at appropriate concentrations could increase the germination percentage of seeds. Of the three PGRs used in the study, GA3 was found to be the most effective at enhancing seed germination for all four plant species, followed by IAA and IBA. Overall, this research has demonstrated that the use of PGRs can significantly improve seed germination percentage and can provide valuable insights into the optimal concentration of PGRs required for the best possible results. The study results could potentially assist in the development of PGR-based strategies to enhance plant growth and productivity, which could have important implications for agricultural and environmental sustainability.
