Fragmentation pathway studies of several plant hormones using an electrospray ionization-quadrupole

Fragmentation pathway studies of several plant hormones using an electrospray ionization-quadrupoleAbstractAuxins, cytokinins (CKs), gibberellins (GAs), and abscisic acid (ABA) are four classes of plant hormones, which play important roles in phytophysiology. However, few mass spectrometric fragmentation pathway studies of these compounds have been performed..
