摘要: A sensitive and specific radioimmunoassay was used to determine quantitatively four of the most important phytohormones in phloem exudate from 14 different tree species 8 genera. For cytokinins indole-3-acetic acid (IAA) we found higher concentrations than those reported previously for other species. The gibberellin values were same order magnitude as earlier analyses (with methods) exudates, but lower ones Ricinus. Free abscisic (ABA) exudates similar before Yucca or palm exudate, at considerably Ricinus Lupinus exudate.
