Abstract : The ripening potential and behaviour of mango cv. Lirfa fruits in relation to harvesting date (fourteen weeks after full bloom until the yellow point) and carbon nutrition as dictated by the leaf:fruit ratio (10 and 100 leaves per fruit) were determined. Dry matter, starch and total sugar content were higher with high leaf:fruit ratio. Under the higher leaf:fruit ratio, ACC and malonyl-amino-cyclopropane-carboxylate (MACC) contents did not differ significantly during fruit development and increased only when the fruit ripened. MACC content increased dramatically under the lowest leaf fruit ratio. Faster senescence was observed during the yellow point harvesting of fruits. MACC content in fruits under 100 leaf:fruit ratio were relatively stable during storage, whereas ACC and MACC contents varied greatly under 10 leaf:fruit ratio.
