Growth of Grape Rootstock (‘Glorie’) Applying Cylindrical Paper Pot by Irrigation Method

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/m 2 /day, 5,642 g/m 2 /day and 6,681 g/m 2 /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.
