Abstract
A study was undertaken to investigate the effect of hydropriming on the germination of Tongod Wangi upland rice seeds. All experiment were carried out at the Faculty Sustainable Agriculture, Universiti Malaysia Sabah. Two seed lots: non accelerated aged (non-AA) and accelerated aged (AA) were used. Both lots were hydroprimed for 0, 6, 12, 24 and 48 hours in tap water at 30 ± 2°C. After priming, seeds were air dried. Seed moisture content and germination were determined. The initial moisture content was found to be 8.37 % for non AA seeds and 19.22 % for AA seeds. Seed germination percentage was recorded to be 86.75 % and 84 % for non AA and AA seeds, respectively. Both AA and non AA seeds displayed the triphasic moisture absorption pattern. Seed germination increased with the increase in hydropriming up to 24 hours. Parameters on seedling growth and development showed that hydropriming of non AA and AA seeds was beneficial for seeds primed for 6 to 12 hours. However, extending the duration of priming to 48 hours resulted in deleterious consequences on seedling growth and development.
