This study was conducted to evaluate the effects of cylindrical paper pot (PP) size, irrigation method and irrigation frequency in ‘Glorie’ as a remarkable rootstock of grape in Korea. ‘Glorie’ was utilized into 2-, 3-, and 4-inch PPs, watering with overhead irrigation, subirrigation and their mixed method, and irrigation frequency was 1 time every four days. Evapotranspiration amount of ‘Glorie’ stock seedling on 30, 60, and 90 days after planting (DAPs) was investigated 4,526 g/m2/day, 5,642 g/m2/day and 6,681 g/m2/day. The dry weights of leaf and root in the 2-inch PP treatment on 90 DAPs were increased by 52.9% and 11.2%, respectively than those of control (no PP treatment). As compared to control, dry weight of leaves and root, and root length of 2-inch PP watering overhead irrigation (2PP-O) on 90 DAPs were increased 52.7%, 7.2%, and 10.8%, respectively. Compared to control, dry weight of leaves and root, and root length of 2-inch PP treatment watering four days interval with overhead irrigation method (2PP-W1) on 90 DAPs was increased by 52.7%, 7.2% and 10.8%, respectively. These results indicated that when ‘Glorie’ seedling applying PP was planted in 2-inch PP, and then watered every four days with overhead irrigation method, it increased the growth of grape rootstock seedling by improving growth of root and leaf.
