The production of quality plantain seedlings way macropropagation in a thermal chamber is an economical and efficient methodology for small producers. The aim of the research was to evaluate the effect of benzylaminopurine and type of sprouts on the multiplication rate of corms and the quality of plantain seedlings propagated in a thermal chamber. Two separate experiments were performed. 1) To test the effect of benzylaminopurine (BAP) on the multiplication rate of plantain corms in a thermal chamber, two treatments were established were: With BAP (40 mg L-1) and without BAP. 2) To test the rooting ability, growth and seedlings quality plantain in the nursery phase generated from two types of sprouts in a thermal chamber that were: Second-generation adventitious sprouts (ASR2) and sprouts from callus tissue (CSR2). In both experiments, the data were analyzed with the Student's t test for paired observations. The multiplication rate, growth variables and quality of seedlings in the nursery were recorded. The highest rate of multiplication of sprout in thermal chamber occurred with BAP, which was 44% higher than the treatment without BAP. The highest growth and quality index of Dickson in seedlings during acclimatization was achieved with adventitious sprout (ASR2). The quality was positively correlated with morphometric variables of the seedlings. The use of BAP and adventitious sprout (ASR2) is effective in increasing the multiplication rate and quality of macropropagated plantain seedlings.
