摘要： In order to further assess the feasibility of monitoring the chlorophyll fluorescence parameter F-v/F-m in compact corn by hyperspectral remote sensing data, in the present study, hyperspectral vegetation indices from in-situ remote sensing measurements were utilized to monitor the chlorophyll fluorescence parameter F-v/F-m measured in the compact corn experiment. The relationships were analyzed between hyperspectral vegetation indices and F-v/F-m, and the monitoring models were established for F-v/F-m in the whole growth stages of compact corn. The results indicated that F-v/F-m was significantly correlated to the hyperspectral vegetation indices. Among them, structure-sensitive pigment index (SIPI) was the most sensitive remote sensing variable for monitoring F-v/F-m with correlation coefficient (r) of 0.88. The monitoring model of F-v/F-m was established on the base of SIPI, and the determination coefficients (r(2)) and the root mean square errors (RMSE) were 0.812 6 and 0.082 respectively. The overall results suggest that hyperspectral vegetation indices can be potential indicators to monitor F-v/F-m during growth stages of compact corn.
