The in vitro synthesis of phytate was studied in common bean fruit explants. Different concentrations of sucrose; phosphorus (P); myo-inositol; abscisic acid (ABA); glutamine and methionine, were tested. Fixed concentrations of these compounds were tested at different periods (0, 3, 6 and 9 days). Variation in phytate coincided with different concentrations of sucrose, myo-inositol, P and ABA for the duration tested. These compounds caused an accumulation of phytate and were more effective in

In conclusion, P, sucrose, ABA, and myo-inositol caused an increase in the phytate of bean seed, showing that it could be possible to alter its content by culturing bean fruit explants in vitro.
