The Lodicules of Wheat: Pre- and Post-Anthesis

Abstract

Development of the lodicules in wheat is described in pre- and post-anthesis flowers. Each lodicule consists of a vascular fleshy body and an avascular membranous wing. At the onset of anthesis, the vascular region swells extensively and subsequently contracts after which the tissues autolyse rap- idly. The membranous wing remains intact. Possible controls and mechanisms of the swelling and destruction of these small organs are discussed.
