Enhancing Deteriorated Corn (Zea mays) Seed Quality through Priming Treatment Using Various Solutions and Soaking Duration
Downloads
Abstract
Maize is one of the major staple food crops, so it is widely cultivated worldwide. High-quality seed is important as planting material, but it undergoes deterioration during storage. This study aimed to enhance the quality of deteriorated seeds during storage. The experiment was conducted using a randomized complete block design with two factors and four replications. The first factor was seed variety, comprising Bonanza F1, Favorite, and P39. The second factor was osmopriming treatment, which consisted of control (untreated seeds), GA3 200 ppm for 18 h, GA3 200 ppm for 36 h, 10% PEG for 12 h, 10% PEG for 24 h, 1% KNO3 for 12 h, and 1% KNO3 for 24 h. The results showed that Bonanza F1 and Favorite (expired 2020) had lower seed quality than P39 (expired 2024). Osmopriming did not enhance germination in Bonanza F1, but osmopriming with 10% PEG and 1% KNO3 for 12 h did enhance germination percentage in Favorite. Priming enhanced the seed quality of seed stored for three months, with GA3 200 ppm for 18 h and 10% PEG for 12 and 24 h as the best treatments for germination percentage, while GA3 200 ppm for 18 h and 1% KNO3 for 12 h for seedling dry weight. Priming with GA3 200 ppm for 18 hours resulted in higher radicle emergence in P39 and Favorite.
