Abstract
Abstract Seeds of pepper (Capsicum annuum cv. Staddon’s Select) with radicles from 0 to 8.6 mm in length were examined for their sensitivity to 0°C exposure by means of a low temperature emergence assay. If seeds were unchilled, radicle length and time to 50% emergence were inversely related. After 4 days at 0°, seeds with long radicles emerged as slowly as seeds with short radicles. Percent emergence after 4 days at 0° was greatly reduced for seeds with long radicles. Seeds with long radicles had a higher rate of respiration and a lower amount of glucose equivalents than seeds with short radicles. The faster depletion of food reserves in seeds with long radicles may contribute to their slowed emergence in cold soil.
