Germinability and storability of pre-germinated rice (Oryza sativa L.) seeds
In rice growing areas where wetland broadcasting is practiced, farmers always face a problem with seed loss from left-over, pre-germinated seeds. The objectives of this study were to evaluate the ability of the pre-germinated rice seeds to withstand drying and storage to determine whether or not pre-germinated seeds can be used as planting material. Two lots of rice seeds, newly harvested and naturally aged, were prepared for pre-germination by soaking for 24 hours and then incubating for 0, 12, 24, 36 or 48 hours. After soaking and incubating, the pre-germinated seeds were dried back to 12% moisture content and stored for up to eight weeks. The pre-germinated seeds of both seed lots could successfully re-germinate with germination percentages being higher than 80%. The pre-germinated seeds could be stored up to 5-6 weeks for newly harvested seeds and 4-5 weeks for naturally aged seeds. It can be concluded that pre-germinated rice seeds could be dried back and stored as planting material for 4-6 weeks.
