A COMPARISON OF REPRODUCTIVE EFFORT IN THE DIOECIOUS SHRUB OEMLERIA-CERASIFORMIS USING NITROGEN, ENERGY AND BIOMASS AS CURRENCIES

Energy concentration was very similar among reproductive structures and among individual plants. Concentration of N was highest in flowers and flower peduncles of both sexes (3.78-5.20%), much lower in fruits (1.77%) and lowest in fruit peduncles (1.03%). In terms of N, reproductive effort of females was almost twice that of males; in terms of energy or biomass, the difference was c4-fold. -from Authors
