Abstract:
:The levels of free and ester-linked indole-3-acetic acid (IAA) in different parts of the maize root were measured using gas chromatography-mass spectrometry (selected ion monitoring). In roots of 2-day-old plants, the distribution of free and ester IAA differed both along the root and between stele and cortex. The levels of IAA and IAA esters were then measured in whole roots and in the elongation zone using roots of different ages. The level of ester IAA decreased steadily with time. In contrast, the level of free IAA in the elongation zone was found to increase after a few days of culture at which time the rate of root growth was decreasing.
