植物激素对生物和非生物胁迫以及植物的生长发育具有协同和拮抗作用。因此，需要一种同时测定几种植物激素的分布和浓度的技术。以前，我们报道，本地化的两种植物激素[细胞分裂素（CK）和脱落酸（阿坝）]可以同时可视化在植物组织中使用基质辅助激光解吸/电离（MALDI）质谱（MS）。然而，在MALDI-MS中，有机基质的自电离偶尔会干扰小分子的电离（
Plant hormones can act in synergistic and antagonistic ways in response to biotic and abiotic stresses and in plant growth and development. Thus, a technique is needed to simultaneously determine the distributions and concentrations of several plant hormones. Previously, we reported that localizations of two plant hormones [cytokinin (CK) and abscisic acid (ABA)] can be simultaneously visualized in a plant tissue using matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS). In MALDI-MS, however, self-ionization of an organic matrix occasionally interferes with ionizations of small molecules (
