D ifferent fruit partsnamely pe- duncle vascular bundle, sepa,l pericarp, pectinic, dissepiment and fruit vascular bundle were taken in order to determ ine carbohydrate composition and content and sucrose-metabolizing enzymes activities of each part during tomato fruit development. The results indicated that a negative correlation was found bewt een glucose and fructose contents and sucrose synthase (SS)activity during fruit development. The correlation coefficients * ** were -0.9497 and - 0.9598 〔r(0.05, 3) =0.8783, r(0.01, 3)=0.9587 〕, respectively. A positive correla- tionwas found between invertase activity and glucose and fructose contents, while there was a significant nega- tive correlation bewt een the invertase activity and the sucrose content. The correlation coefficients were - 0.9706**and - 0.9669** 〔r(0.01, 3)=0.9587〕, respectively. There was a significant positive correlation between sucrose accumulation and SS activity, with the correlation coefficient being 0.8886* 〔r(0. 05
