Abstract:

Determining for banana nitrate uptake kinetic more reasonable data treating method and parameter dimension, three data processing methods and three parameters expression dimensions were investigated by modified depletion method. The results indicated that, the kinetics parameters for nitrate uptake were changeable dependent upon data processing and dimension. Conclusion were draw that, method of Lineweaver-Burke (LB) was the best one with veracity among those data processing based on the values of R2, range of 0.918-0.988, got to 5% significant level. It was more reliable to the kinetic parameters when dimension was expressed as root dry weight or root fresh weight with 1% significant level, and Vmax and Km had consistent change trend.
