| Outline of Final Research Achievements |
This study investigated the factors affected to the difference in radioactive cesium (RCs) accumulation in grain between wheat varieties. ‘AU49’ had higher RCs concentration than ‘Shiroganekomugi’ in low exchangeable potassium condition in soil. On the other hand, ‘Shiroganekomugi’ had higher RCs concentration than in high exchangeable potassium condition in soil. The difference was affected by the transportability of RCs from shoot to grain. Transportability of potassium from root to shoot was higher in ‘AU49’ than in ‘Shiroganekomugi’. From these results, it was considered that potassium demand was higher in ‘AU49’ than in ‘Shiroganekomugi’. RCs is similar with potassium in chemical property. Higher demand of potassium in ‘AU49’ my be a reason that ‘AU49’ had higher grain RCs concentration than ‘Shiroganekomugi’ in low exchangeable potassium condition in soil.
