This study was conducted to find out the effect of treatment on the concentration in guttation liquid, the amount of guttation liquid exudated from the margin of rice leaves, and the relationships between concentration in guttation liquid and foliar burn during the rice seedling stage, using two rice varieties;Nagdong-byeo (a Japonica) and Samgang-byeo (a - Indica - Japonica hybrid). Seedlings were cultivated in water solution and enveloped in polyvinyl case (). treatment increased the amount of guttation liquid, the amount of guttation liquid (Nagdong-byeo:4.30mg/plant, Samgang-byeo:4.34mg/plant)) treated with 200ppm of was greater than any other level, decreased over 200ppm of . concentration in guttation liquid was increased as application rates of increased, showing the positive correlation, and in guttation liquid/ in culture ratio decreased over 100ppm of . The highest concenitration of (Nagdong-byeo:172.6ppm/lcc, Samgang-byeo:199.8ppm/lcc) in guttation liquid was obtained at 12 hrs after applied. Foliar burn seemed to be closely related with concentration in guttation liquid.
