GENOTYPES. Rev. Bras. Frutic. [online]. 2001, vol.23, n.3, pp. 546-550. ISSN 0100-2945. http://dx.doi.org/10.1590/S0100-29452001000300019.
Physical and chemical quality were valued of six carambola (Averrhoa carambola L.) cultivars, spreaded to the Bebedouro Experimenal Citrus Station, São Paulo, with purpose to obtainment informations about fruit quality in this region. Were utilized fruits of Tean-ma, Fwang Tung, Arkin, Malaysia, Golden Star and Nota-10 cultivars. The fruits were analysed to fresh weight, length, breadth, volume, percentage of juice, residue and seed, seed numbers, coloration (L, Chromaticity and Hue angle). In pulp, were determined pH, as well as, the content of moisture, total soluble solids (TSS), total titratable acidity (TTA), vitamin C, total soluble sugars and reducings, ash, protein, total and soluble pectin, and minerals (Ca, P, K, Mg, S, Cu, Fe, Mn and Zn). The results were statiscaly valued according to completely randomized desing and showed Arkin, Tean-ma and Nota-10 cultivars, were the best fruits, because were larger, weighter and presented higher content of total soluble solids (TSS) and soluble sugars, as well as, good TSS/TTA ratio. Arkin fruits showed more yellow coloration while Golden Star's were considerate light, or more translucent. The texture was small in Arkin fruits an to linked with more pectin disasembly.
