Abstract
The response of chlorophyll fluorescence parameters characteristics and spectral reflectance in New sugarcane 22(T22) were studied under 4 different water treaments in pots. The results showed that, except qN increased, other chlorophyll fluorescence parameters as Fv/Fm, PS ¢ò, rETR and qP decreased with increasing of water stress. Photo system can be injuried by drought, the injury will be further intensified as water stress exacerbated. The general trend of spectral curve was consistent under different water treaments, the same peaks and valleys, However, the band reflectance values were different, the canopy reflectance of most bands were CK
