Abstract

We estimated the above-ground biomass and the adaptability of four-year-old five poplars in a riparian buffer forest established in the Namhan River in Yang Pyeong, Korea. Average survival rate of poplars was 85.7%. Populus deltoides hybrid clone 'Dorskamp' showed the best survival rate of 91.6%. P. deltoides hybrid clone '97-19' showed the highest above-ground biomass, which was estimated as 54.6 ton/ha at age 4. On the other hand, P. koreana × P. nigra var. italica clone 'Suwon‘ showed the lowest in above-ground biomass. For leaf damage of poplars, the '97-19' seemed to have strong tolerant when compared to the other species. However, 'Suwon’ showed the highest in leaf damage. '97-19' showed the best adaptability, which was estimated with survival rate, biomass, vitality and damages by diseases and insects in riparian area and followed by 'Dorskamp'. As the consequence, the two poplars seemed to be the best candidate poplar species for the establishment of riparian buffer forest.
