Effects of low soil temperature on the growth and maintenance of Japanese white oak under the conditions of low light intensities (19 μmolm-2s-1) were investigated. Trees (Quercus myrsinaefolia Blume) were kept in environment controlled chambers during the experiment at the soil temperatures of 5°C and 25°C. The net photosynthetic rate, dark respiration rate, transpiration rate and stomatal conductance were affected by the soil temperature. The net photosynthetic rate at the soil temperature of 5°C was higher than at the soil temperature of 25°C. The dark respiration rate was lower in 5°C soil temperature treatment than that at 25°C soil temperature. The higher net assimilation rate at the 5°C soil temperature was regarded as one of the reasons of the longer life of indoor trees under the lower soil temperature conditions.
