Note: Tr, sucrose transformation rate; DPA, days post anthesis; Values followed by a different letter between salinity levels are significantly different at P = 0.05 probability level. Each value represents the mean of three replications. LS: low soil-salinity, MS: medium soil-salinity, and HS: high soil-salinity.
