The (~)-abscisic acid content of pea shoots has been determined using gas-liquid chromatography. In both tall and dwarf cultivars no significant difference was observed between plants grown in the dark or under red light. Nor was the difference between the tall and dwarf cultivars themselves signifi

When shoots of 6-day-old, dark-grown peas were excised 30 mm below the apex and floated on a solution of radioactive gibberellin A 1 (aH-GA1) or radioactive gibberellin A 5 (3H-GAs), more radioactivity accumulated in the apical part of the stem which responds to GA than in the basal, unresponsive re
Abscisic acid-fl-D-glucopyranosyl ester (ABAGE) has been measured in several plant species using 2H-labelled ABAGE as an internal standard. The effects of water stress on the levels of ABAGE and its possible physiological role are discussed. Some chemical properties of ABAGE are described.
When pea seedlings lose about 5% of their water content the abscisic acid ((+)-ABA) level of the shoots increases ca. 20 times and the level of bound ABA, in all probability ABA-glucose, ca.7-10 times. After watering both ABA and bound ABA contents decrease within 24-48 h to the level in the control
