The study conducted on effect of leaf extract of Ruellia tuberosa L. on the physiological status of floral buds of mango cv. Dusehri Aman (syn. dushehari) revealed that the buds treated with leaf extract of Ruellia tuberosa L. (methanol extract diluted @ 12 g fresh leaf/l water) applied at the time of flower bud differentiation in October showed reduced amount of total phenols and abscisic acid and also the activity of indole acetic acid oxidase and increased amount of indole-3-acetic acid and poly phenol oxidase enzyme activity over control buds. However, the content of gibberellic acid did not differ much in both types of buds.
