Abstract
Aims: To evaluate the seed viability and enhancing germination percentage through plant growth hormones in Anogeissus latifolia. Study Design: A randomized complete block design was used to conduct the investigation. Place & Duration of Study: Plant nursery, ICFRE- AFRI, Jodhpur, Rajasthan, India; between Feb 2023 and June 2023. Methodology: The viability test was analyzed using a 1% Tetrazolium chloride solution (TZ). About 50g seeds were pre-treated with Gibberellic acid (GA3) and Indole-3-Butyric acid (IBA) and hormones of concentrations 500, 750, and 1000 ppm each. 1000 pre-treated seeds of each treatment were sowed in the mother bed of the nursery and germination was recorded for up to 15 days. Further germination indices such as germination percentage, germination speed, mean germination time, root length, shoot length, allometric coefficient, and vigor index were calculated. Results: A. latifolia contained around 33.74±6.561% viable seeds, according to a viability analysis using a 1% TZ solution. An analysis of variance in the data revealed a substantial (P≤.001) impact of PGRs and their interaction with the indices under investigation. The best treatment overall was demonstrated by GA3 750 ppm concentration followed by GA3 1000 ppm and IBA 750 ppm concentrations. IBA 1000 ppm, however, showed a decreased effect on germination studies. Conclusion: Gibberellic acid overall had a beneficial effect on germination and all the studied indices. These hormonal treatments can be used to propagate the plant species for plantation, afforestation, or conservation purposes.
