벼 乾畓直播栽培에서 Propyl Dihydro Jasmonate 種子處理에 따른 出芽 및 生育促進效果 = Effects of Propyl Dihydro Jasmonate on Rice Emergence and the Growth in Direct Seeding on Dry Paddy

다국어 초록 (Multilingual Abstract)

This study was conducted to examine the effects of Propyl Dihydro Jasmonate on the growth responses, chilling tolerance and yields on the direct seeding on dry paddy at seedling stage in two rice cultivars The emergence rate of two rice cultivars (Seoan byeo and Dasanbyeo) were increased more by the treatment of 0.05μM PDJ than those of others. Higher concentration of PDJ was found to be inhibitory for germination. Number of emergence of cultivar Seoanbyeo was higher in 0.05μM PDJ treatment for 24hour as compared to 12hour, whereas, no significant difference was observed in case of cultivar Dasanbyeo Plant height and number of tillers of two rice cultivars were increased by the treatment of 0.05μM PDJ for 24 hour Rice yield of the tested cultivars were increased high in the PDJ treatment plot due to increment of the panicle number in the dry seesed paddy field.
