Abstract

This study was conducted at the School of Sustainable Agriculture Laboratory in Universiti Malaysia Sabah, Kota Kinabalu, Sabah to evaluate the efficacy of six types of germinating media in breaking the dormancy of TQR-2 paddy seeds and to find out how effective was clean collected rain water in breaking the seed dormancy. The freshly harvested TQR-2 paddy seeds were soaked in different treatment solutions including 0.2 N HNO³ (control), 0.2 N H²SO₄, 0.2 N Hel, distilled water, tap water and rain water for 12 hours. Then, the seeds were germinated in germination boxes and were observed for 14 days. Complete Randomized Design was used in this experiment with three replications for each treatment. Data for important parameters such as the percentage of seed germination, percentage of normal seedling, percentage of abnormal seedling, number of leaves, seedling height and the length of primary root were analysed by one-way ANOVA. The 0.2 N HN0³ (control) resulted in the highest percentage of seed germination (92.67%) followed by rain water treatment (74.67%). However, 0.2 N HN03 (control) resulted in a high percentage of abnormal seedlings (11.29%) as compared to rain water treatment (4.04%). The lowest percentage of germination was from the distilled water treatment (19.67%). Taking into consideration the percentage of seed germination and percentage of normal and abnormal seedlings, it can be concluded that rain water is the second best to 0.2 N HNO³ in breaking the dormancy of TQR-2 paddy seeds. Therefore, clean collected rain water which is free and abundantly available during rainy season is a good alternative and an efficient agent for breaking the seed dormancy. It can also be recommended to paddy farmers to overcome the problem of any newly harvested paddy variety seeds that are dormant.
