Abstract

This study investigates the effectiveness of seed priming with plant growth regulators (PGRs) such as gibberellins (GA) and naphthaleneacetic acid (NAA) in improving the germination and growth of different chilli genotypes. Four genotypes were evaluated for various seedling and yield-related traits. Seeds were primed with three levels of GA (GA0, GA250 and GA500) and NAA (NAA0, NAA50 and NAA100), and their effects on germination percentage, germination rate, radicle length, plumule length, seedling vigor index, plant height, root length, number of leaves, number of fruits per plant, and yield per plant were assessed. The results revealed significant improvements in germination percentage and rate with higher concentrations of GA, with GA500 showing the highest effectiveness. NAA priming notably enhanced radicle and plumule length, seedling vigor index, plant height, root length, and the number of leaves and fruits per plant. The study found that the optimal NAA concentration for most traits was 100 ppm. Overall, seed priming with GA and NAA significantly improved various germination and growth parameters in chilli plants, demonstrating its potential as a cost-effective strategy for enhancing crop performance, especially under adverse field conditions. These findings provide valuable insights for resource-limited producers seeking to improve chilli crop yields through effective seed priming techniques.
