“…My data suggest that endogenous cytokinins synthesized in the roots may play an important role in controlling the formation and development of inflorescene (Table 1). Luckwill (15) and Bruinsma (2) showed that application of cytokinin to the root strongly accelerated the flower bud formation of apple. Chen (4) also indicated that application of AL(phenylmethyl)l//-purin-6-amine (BA) to mature mango shoots accelerated flower bud formation in some instances.…”

Changes in gibberellin and cytokinin activities were investigated at the stages of leaf differentiation, mature green leaves, early flower bud formation (7 days after formation), and full bloom of 3-year-old mangos (Mangifera indica L.) in pot culture. Also, diffusible IAA and ABA in the diffusate of shoot tips were examined at the different developing stages. High gibberellin and diffusable IAA activity was found in the xylem sap at leaf differentiation. Diffusible IAA decreased to a low level in shoot tip diffusates, and ABA increased dramatically during early flower bud formation. At the same time, total cytokinin-like activity increased in the xylem sap, reaching a maximum level at full bloom. Chemical names used: 1H-indole-3-acetic acid (IAA); [S-(Z,E)]-5-(l-hydroxy-2,6,6-trimethyl-4-oxo-2-cyclohexen-1-yl)-3-methyl-2,4-pentadienoic acid [abscisic acid (ABA)].
