Fruits of pineapple (Ananas comosus var. comosus) are in great commercial demand and among the most promising cultivars is 'MD-2', which has attracted consumers in recent years. As new cultivars become available, micropropagation techniques can speed the production of high quality plants (vitroplants) of selections with better agronomic characteristics. In Cuba, although some attempts have been made to introduce vitroplants under the production conditions used by State Entities and Agricultural Companies, this objective has not been satisfactorily achieved for various reasons. The present work was to determine the bromatological indicators of the fruits of 'MD-2' pineapple plants coming from micropropagation. These indicators were physical and chemical according to the 1982 Cuban Standards (total soluble solids (°Brix), titratable total acidity (%), ascorbic acid (mg 100 g(‑1) juice) and fruit pH). Bromatological analyses carried out on the fruits showed that they complied with the characteristics of 'MD-2' pineapple, even though the agrotechnics used were different from what is traditionally used for the 'MD-2' crop, the results obtained did not show differences in total soluble solids (12.8 to13.2 °Brix), titratable acidity (0.7 to 0.8%) or citric acid.
