Abstract
Extrinsic environmental cues and intrinsic developmental stages of the flower control the production of scent from flowers. Flowers emit seem only when they are open; yet, the precursors for the aromatic compounds are also present in buds, stored as non-fragrant glycosides in the vacuole. We demonstrate that in Narcissus flowers scent emission is concurrent with an increase in the activity of β-glucosidase. The inhibition in vivo of β- glucosidase activity decreases scent emission from Narcissus flowers. The β- glucosidase activity was partially purified and the K(m), V(max) and inhibition by gluconic acid lactone was determined.
