Both water-saving management and Zn fertilization
significantly reduced the molar ratio of phytic
acid to Zn in the polished rice (Table 5). Compared to
CF, the molar ratio of phytic acid to Zn was significantly
decreased by 25.8% under AWD treatment.
The molar ratio of phytic acid to Zn ranged from 11.9
in no Zn treatment to 8.9 by ZnSO4 application and to
9.4 by Zn-EDTA application, and decreased overall
by 33.7% and 26.6%, respectively. However, no significant
difference was observed in the molar ratio of
phytic acid to Zn between the two genotypes (Table 5).
