The leaf area index is a key parameter for studying many physiological processes associated
with urban and rural trees. Leaf area index was measured based on weight and also component of
specific leaf area and ground area generated in previous research (Ushada and Murase, 2006). The
leaf water potential can be pertinent index for describing the water status of a plant (Murase et al.,
1997). Leaf water potential was measured using a Wescor HR-33T dew point microvolt meter in
conjunction with a C52 chamber. Those biological data were used for ANN model output .
