Determination of Abscisic Acid in Pinus densiflora by Selected Ion Monitoring.
Abscisic acid (ABA) in the stem of akamatsu (Pinus densiflora) was identified and quantified by gas chromatography-mass spectrometry-selected ion monitoring using hexadeuterated ABA as an internal standard. tert-Butyldimethylsilyl ester was used as a derivative of ABA. This derivative had high sensitivity and selectivity for ABA determination. ABA concentrations in cambial region scrapings were independent of the cessation of cambial activity.
