Abstract

In arecanut, the spadix which is enclosed completely by a boat-shaped spathe, is infrafoliar in location. So every leaf-fall should be accompanied by a production of an inflorescence, provided inflorescence primordia are present in each leaf-axil. However, when the leaf is shed, inflorescence is absent in a number of leaf axils. Khandige et al. (1956) reported seasonal variation in the percentage of inflorescence to the leaf-fall for middle-aged (25-35 years) palms. Bavappa and Ramachander (1967) observed a correlation of 0 -41 between number of inflorescences produced and yield. No information is avaiUble about the mode of initiation of the inflorescence, its course of development and the natural variation existing in its failure. Studies taken up on these aspects are reported in this paper.
