| Popis: | ABSTRACT: Acclimatization is the final phase of banana plantlet production by micropropagation. In this phase, the plantlets are grown in a protected environment with high demand for water, fertilizer and labor, until reaching the standard size and quality required for marketing. The aim of this study was to evaluate the possibility of reducing these costs and the duration of the acclimatization phase, using the hydroponic cultivation technique as compared to the conventional system. ‘Prata–Anã’ banana plantlet performance was measured for both systems under both tropical summer and winter conditions, based upon water and nutrient use efficiency and growing time of the plantlets. In both seasons, the plantlets produced hydroponically presented faster growth of both the shoot and root systems. There was a reduction of 12 days to reach the transplantation point, a significant reduction in plantlet production cost (fertilizers + water) and improved efficiency in space use with an expressive increase in the number of plantlets produced per square meter. |
