This study aimed to examine the development of kudzu (Pueraria lobata) that is a semi-woody vine plant around buildings in relation to solar radiation interception. Kudzu nursery stocks were transplanted beside containers (2.6 m high, 3.65 m wide and 1.83 m deep) in May, and trained to climb plastic nets placed on the south wall and the roof of the containers. Frames (0.4 m x 0.4 m) for measurement were set at different positions on the south wall and the roof. We regularly measured covering rate by plants in each frame every 2 weeks, and measured solar transmissivity, covering rate, leaf area, leaf number and stem length in October. The correlation coefficient of solar transmissivity with covering rate was higher than the other traits. The covering rate of the upper position on the south wall and the south position on the roof increased more rapidly than the other positions. Covering rate, LAI and leaf area of the upper position on the south wall were higher than the other positions. Moreover, the correlation coefficient of covering rate with leaf area was higher than leaf number. As such, leaf development peaked at the upper position on the south wall and slowed down on the roof, and this changing pattern largely determined the changing pattern in light interception.
