Abstract：The physiological characteristics of calcium(Ca)accumulation in wheat grains and correlations between Ca concentrations in grains and that in flag leaf blades,flag leaf sheaths,peduncles,internodes,spike-stalks and glumes were investigated in this study.The results showed that the Ca concentration and Ca accumulation rate in grains decreased gradually,while the total Ca in grains increased with the extension of filling time.Correlation analysis revealed that the Ca concentration in grains negatively correlated with that in leaves,leaf sheaths,peduncles,internodes,spike-stalks,and glumes.With the extension of filling time,the Ca concentration in internodes,spike-stalks and glumes increased differently,while that in leaf blades and leaf sheaths did not change.The results indicated that Ca in leaf blades and leaf sheaths could not be transported into grains,and the Ca in grains was mainly transported from roots.
