초록

Prunus × yedoensis is a representative tree species in residential areas often used as a street tree or park tree, with its popularity due to splendid flowers in the spring. We investigated plant growth, photosynthesis, chlorophyll, and carotenoid concentrations of Prunus yedoensis at 400ml/pot, 1,000ml/pot, and 2,000ml/pot Irrigation treatments. Overall growth indices such as tree height, diameter at root collar (DRC), and total dry weight could be ranked in the decreasing order "2,000ml/pot > 1,000ml/pot > 400ml/pot.". However, 2,000ml/pot featured decreased photosynthesis and total chlorophyll carotenoid contents than 1,000ml/pot treatment after July. And also, The 1,000ml/pot treatment showed relatively high photosynthetic activity and chlorophyll contents. These results suggested that the cultivation of Prunus yedoensis under 1,000ml/pot Irrigation treatment(soil water contents 25~35%) showed the best condition in growth.
