Abstract

Most of the elongation responsible for barnyardgrass seedling emergence occurred in the first internode. The developing foliar leaves within the coleoptile were the consistent site of EPTC injury. Injury symptoms were never observed in the roots. The first internodes of EPTC-injured seedlings seemed to function normally, although they were sometimes kinked into zig-zag patterns. This kinking was a secondary rather than a direct effect of EPTC injury. Seed germination was not affected by EPTC. Injury occurred after germination. Exposing the seed and primary root to EPTC did not lead to injury, whereas exposing the shoot or only the coleoptile did. It was concluded that leaf tissue is the main site of EPTC uptake in barnyardgrass as well as the prime site of injury.
