The distribution of carbon‐14 down the stems of comparable boron‐deficient and boron‐sufficient sunflower plants after photosynthesis of 14 CO 2 by a single exposed leaf was investigated. In boron‐deficient plants the advancing front of radioactivity was always found less far down the stem than in boron‐sufficient plants. The general shape of the profile is the same in the two sets of plants. We conclude that the velocity of translocation is reduced in the boron‐deficient plants.
