โฆ Synopsis
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.
