dc.description.abstractOne of the potential ways of increasing rice production to cater for ever increasing population of Malaysia is to extend the production area of lowland rice through its production as upland rice. Therefore, this research was conducted to determine the effects of seed priming in alleviating water deficit stress in lowland rice produced as upland rice. The treatments used were 100mM calcium chloride dihydrate for duration of 48hours and temperature of 25oC, 40% w/v polyethylene glycol (PEG) 6000 for a duration of 48hours and temperature of 25oC, 100ppm kinetin for a duration of 24hours and temperature of 4oC, 200ppm methyl jasmonate for a duration of 24hours and temperature of 4oC, stressed control (unprimed seeds) and the unstressed control (unprimed seeds with adequate irrigation). The experiment was laid out in randomized complete block design (RCBD) with three replications. Data were collected on classical growth parameters, germination pattern, gas exchange characteristics, yield and yield components. It was found that priming MR219 rice with PEG could enable the variety to be produced as upland rice with little yield reduction because PEG priming was the best in individual seed mass, final yield, harvest index and water use efficiency. It is, therefore, concluded that 48hours of priming with 40%w/v polyethylene glycol at 25oC be used for MR219 rice seeds whenever MR219 rice variety is to be cultivated as upland rice.en_US
