영문 초록

This study used the data of full blooming date and temperature of landscape woody plants to estimate the base temperature and Growing Degree Day(GDD) according to plant phenology. The full blooming date of landscape woody plants from 2011 to 2012 was investigated, and the GDD was calculated by deducting the base temperature from daily mean temperature using the temperature data of Suwon Regional Meteorological Office. To set up the reference temperature, the GDD is calculated in the unit of 0.1℃, setting the temperature with low standard deviation of GDD from 2011 to 2012 as the base temperature. As a result, the base temperature of plants is 1.9℃ for Rhododendron mucronulatum Turcz., Cercis chinensis Bunge. and Daphne odora Thunb., 0℃ for Spiraea cantoniensis Lour., and 1.2℃ for Grewia parviflora Bunge.. The GDD of the full bloom stage is 324.10±96.32℃d for R. mucronulatum Turcz., 506.90±84.99℃d for C. chinensis Bunge. and D. odora Thunb., 853.65±59.61℃d for S. cantoniensis Lour., and 2112.70±11.74℃d for G. parviflora Bunge. The comparison of predicted full bloom date and actual full bloom date in Hongreung Arboretum using the calculated GDD showed that 45% of the predicted fullbloom date for R. mucronulatum Turcz. matched the actual full bloom date, 35% for C. chinensis Bunge.. D. odora Thunb. has similar full bloom date with C. chinensis Bunge., and thus may show similar prediction accuracy.
