This research aims to study the physiological characteristics of poplar clones in Saemanguem reclaimed land where has lower minerals and bad drainage than those in paddy field. In July and August, different poplar clones including Populus euramericana clone (Venziano and L.Avanzo) and deltoides hybrid clone (97-18 and 97-19) showed different physiological characteristics. Physiological characteristics of P. euramericana clones were better than those of P. deltoides hybrid clones. Especially, the average net photosynthetic rate (Anet) of clone Venziano were 18.62 μmol CO2 m-² ㆍ s -¹ and 17.11μmol CO2 m-² ㆍ s -¹, respectively. Those were the highest numerical values among other poplar clones. On the other, the total chlorophyll and carotenoid contents of P. deltoides hybrid clones were higher than those of P. euramericana clones in July. Particularly, the total chlorophyll content of clone 97-18 was 2.37 mg ㆍ g -¹FW. In August, those of P. deltoides hybrid clones decreased than in July. In term of the physiological activity such as net photosynthetic rate and stomatal conductance of P. deltoides hybrid clones were much lower in August than in July. As a result, physiological characteristics of P. euramericana Venziano clone was superior than the other clones in Short rotation coppice (SRC) in Saemanguem area.
