Starch and ethanol-soluble sugar components were determined in the shoot tip and in the achlorophyllous - and chlorophyllous part of the subtending leaves during the ontogeny of the pineapple plant. The changes observed were correlated with rooting process in the propagule, vegetative growth of the plant and the change to the reproductuve state inflorescence formation, induced by natural environmental conditions. The carbohydrate distribution pattern in the chlorophyllous leaf part was suggestive of dependence on the metabolic changes in the pineapple shoot apex. A physiological role for the achlorophyllous leaf part has been proposed. The significance of the distribution of carbohydrate between the readily assimilable soluble form (sugars) and the insolublestorage form (starch) has been briefly considered in relation to the tissue and the stage of growth. |
