Effect of Irrigation Regimes on Concentrations of Phytic Acid and Minerals in Hulled and Naked Oats
The effects of irrigation regimes, cultivar and irrigation × cultivar interaction on the concentrations of phytic acid, total phosphorus, crude protein, Ca, Mg, K, Zn, Fe, Cu and Mn in oat grains were determined. The relationships between the variables under study and irrigation quota were estimated with linear and quadratic regression models in hulled (Avena sativa L. ) and naked (Avena nuda L. ) oats. Significant differences were obtained among irrigation treatments, between the two oatvarieties and irrigation × cultivar interaction for most of the variables under study. Changes in grain total phosphorus and copper contents with the increase of irrigation times and quota were linear while those in phytic acid, Ca, Mg, K, Zn,Mn were quadratic in naked oat. Changes in hulled oat grain (husked) Zn and Fe contents with the amount of irrigation were linear while those in phytic acid, total phosphorus, crude protein, Ca and Mg contents were quadratic. Phytic acid content of hulled oat was highly correlated with total phosphorus, crude protein, Ca, Mg and Zn (p＜0.01). In contrast, no significant correlations were observed in naked oat. Grain yield was positively and significantly correlated with phytic acid, total phosphorus and protein, but negatively correlated with Ca, Mg and Zn in hulled oat. The grain yield of naked oat was positively associated with phytic acid,Ca, Mg, K, Zn, Fe, and Mn contents.
