Abstract: Banana plantlets obtained by micropropagation need to be submitted to a period of acclimatization since they do not use light, water, and nutrients in an efficient way. The acclimatization must be carried out under greenhouse conditions where temperature, light, and air humidity are adequate for a gradual hardening of the plantlets. In this study, the development of banana plantlets was evaluated during acclimatization under a full light condition including covered surfaces with red shade cloth (70%, 50%, and 30% shade) and black shade cloth (50% shade), both under a transparent plastic film of 100 μm. Temperature, relative air humidity, irrigation, and nutrition conditions were also controlled. Physical and physiological parameters were recorded at various stages in the greenhouses after three, six, and nine weeks and also after seven weeks of transplanting to field conditions. Treatments were hierarchically graded according to their statistic classification. Combined results indicated superior outcomes of plantlets maintained under black 50% shade cloth for nine weeks, both in the summer and winter seasons. Similar results, but in a shorter time, were obtained with plantlets cultivated under red 70% shade cloth, for six weeks in the summer.
