    Axillary buds, collected from greenhouse-grown plants of Bambusa vulgaris Schrad. ex Wendl (B. vulgaris), were incubated on a static liquid culture medium, Murashige and Skoog (MS) medium with 2% (w/v) sucrose, and supplemented with 12.0 μM 6-benzyladenine (BA). They were transferred to a temporary immersion system (TIS) using liquid MS medium supplemented with 0 (CK-free medium), 6.0, 12.0, 18.0 μM BA. The morphological and anatomical indicators were measured. The BA influenced in vitro multiplication of B. vulgaris. The best results were achieved in the SIT with a concentration of 6.0 μM of BA, which increased the number of shoots (5.1 shoots/explant) in the absence of hyperhydric shoots. Results demonstrated that the water content in the sprouts increased with 12.0 and 18.0 μM BA every four hours. Furthermore, these high levels of BA contributed to a lower accumulation of phenolic compounds and lignin content. The total chlorophyll significantly increased when using 6.0 uM BA, but decreased both parameters with other treatments. These results favor to increase the number of shoots/explants during in vitro multiplication. They will also optimize the in vitro culture conditions, leading to an improvement of in vitro propagation methods for this species.

    In Cuba, banana production is destined for the national market as fresh fruit and plays an essential role in food security. The objective of this work was to evaluate in field conditions the morpho-agronomic and organoleptic characteristics of five banana cultivars Williams ( Musa AAA), ‘Parecido al Rey’ ( Musa AAA), ‘Formosana’ ( Musa AAA), ‘FHIA-17’ ( Musa AAAA) and 'Grande naine' ( Musa AAA) in Quemado de Guines. For this study, 300 plants of each cultivar were planted at a distance of 3 x 2 x 2 m in a red ferralitic soil. The evaluations were carried out at the time of flowering and at harvest, during the first growing cycle. The results showed that the height of the plant and the circumference of the pseudostem had the lowest average values in the cultivar 'Grande naine'. The greatest number of functional leaves at the time of flowering occurred in the cultivars ‘Parecido al Rey’ and ‘Williams’, with values of 9.6 and 10, respectively. The ‘FHIA-17’ cultivar showed the highest values in the yield components. The total soluble solids content in the organoleptic maturity was 15.60% for the ‘Grande naine’ and ‘Parecido al Rey’. The banana pulp was characterized by presenting an acid pH in all cultivars. The results of this work provide important information for the design of varietal strategies, for the use of these cultivars in banana production for the national market and tourism.
