The transport and distribution of 14C‐ sucrose and 14C‐ BA were studied in internode segments with ear of two winter wheat cultivars with a different mass of kernels in the period of kernel formation. While M C‐sucrose was transported and accumulated intensively in the developing ear, 14C‐ BA was transported much less and only a small part of it was found in the ear. With the ear development the accumulation of both 14 C‐sucrose and 14 C‐BA in the ear increased but the 14 C‐BA distribution pattern (ratio of the internode/kernel and the rest of the ear) did not change significantly. In the period of one to two weeks after anthesis the accumulation of 14 C‐sucrose and 14 C‐BA was higher in the kernels of the Slavia cv., i.e. in the cultivar with a higher mass of kernels.
