The silicon uptake kinetic data treating method and its parameter dimension of banana were studied by the modified depletion method based on 6 banana varieties.The results indicated that the correlation coefficient (R2) of the equations based on 3 data processing methods and 6 dimensions was different;The Lineweaver-Burke (LB) method was the best with veracity among those data processing based on the value of R2,range of 0.955 8-0.998 3,got to 1% significant level;Hofstee (H) method was not suitable for banana silicon uptake kinetics.
