Quantification of abscisic Acid in a single maize root

Plant Physiol. 1987 Sep;85(1):8-9. doi: 10.1104/pp.85.1.8.

Abstract

Quantitative analyses of abscisic acid in the elongating zone of a single maize root (Zea mays L. cv LG 11) were performed by gas chromatography-mass spectrometry using negative chemical ion ionization. Data showed that the more abscisic acid, the slower the growth, but a large dispersion of individual values was observed. We assume that abscisic acid is perhaps not correlated only to the growth rate.
