Abstract
Wheat (Triticum aestivum L. cv (9733) seedling (10 day) root length was decreased 60% when plants were watered with 0.01M sodium acetate (NaAc) pH 4.5 in comparison to plants exposed to the same NaAc concen‐ tration at pH 6.0. 3‐indoleacetic acid (IAA) (10‐10 and 10‐9M) (incorporated into the sand potting medium) reversed the excess hydrogen ions (H+) influence.
