Estudios fisiológicos sobre la floración del café en condiciones del sur de India. 6. Cambios en la tasa de crecimiento, ácido indolacético y metabolismo de carbohidratos durante el desarrollo y antesis de la yema floral

Abstract

Studies were carried out on the progressive changes in fresh weight, dry weight, water content, indoleacetic acid, activity of indoleacetic acid oxidase and carbohydrate fractions (reducing, non-reducing and total sugars and starch) associated with different floral phases of Coffea arabica L.cv. "S.795" plants grown under field conditions at Central Coffee Research Institute, Chikmagalur District, Karnataka, South India. The relative quantitative changes in the fresh weight, dry matter cacumulation, water content and chemical compounds (under study) during the initial development, maturity, very little visible growth of mature flower buds, during enlargement of flower buds (after the receipt of blossom showers), in fully opened flowers and also in faded flowers (after pollination and fertilization) are described in detail. The possible metabolic role (s) of these chemical compounds during the different phases of flowering are discussed in the light of the existing knowledge on flowering in plants.
