Keywords:   satsuma mandarin, red edge wavelength, blue shift, water stress

It is effective to control the water stress of satsuma mandarin trees artificially in order to yield fruits with high sugar content. In the remote sensing, it is known that the water stress will cause the blue shift of the red edge wavelength in spectral reflectance of leaves.
