| description | Macropropagation of plantain in a thermal chamber is an economic technology, effective as a method of phytosanitary cleaning, and efficient to enhance the production of seedlings. The aim of the research was to evaluate the effects of corm size (CZ) and benzylaminopurine (BAP) on the proliferation of plantain seedlings cv. Barraganete in two propagation environments (PE). The treatments consisted of two levels of BAP (with and without BAP), three CZ (2±0.5, 4±0.5 and 6±0.5 kg) and two PE (thermal chamber and raised bed). The variables evaluated were budding time (days), multiplication rate (MR) per unit (seedlings per corm) and per area (seedlings per m2). The budding time was significantly influenced (p < 0.05) by the PE, where the thermal chamber advanced the emergence of shoots by 12 days, with respect to the raised bed. The MR of seedlings per corm and m2 were significantly influenced (p < 0.05) by BAP x PE and CZ x PE interactions, where the highest production of seedlings per corm occurred within the thermal chamber with BAP and corms of 6±0.5 kg, while the production of seedlings per m2 was higher with 2±0.5 kg corms under the same thermal chamber conditions and with BAP. The main effects results reported that with BAP there was a 30 and 31% increase in MR per corm and per m2, respectively, in relation to the treatment without BAP. Within the thermal chamber, the MR per corm and per m2 increased by 44% with respect to the raised bed. Regarding the effect of CZ, larger corms reached a higher individual MR, while those of smaller size reached a higher MR per area. It is recommended to use a thermal chamber and BAP to massify the production of plantain seedlings via macropropagation.

La macropropagación de plátano en cámara térmica es una tecnología económica, efectiva como método de limpieza fitosanitaria, y eficiente para potenciar la producción de plántulas. El objetivo del trabajo fue evaluar los efectos del tamaño de cormo (TC) y bencilaminopurina (BAP) sobre la proliferación del plátano en dos ambientes de propagación (AP). Los tratamientos consistieron de dos niveles de BAP (con y sin BAP), tres TC (2±0.5, 4±0.5 y 6±0.5 kg) y dos AP (cámara térmica y cantero). Las variables evaluadas fueron tiempo de brotación (días), tasa de multiplicación (TM) de plántulas por cormo y por m2. El tiempo de brotación fue influenciado significativamente (p < 0.05) por el AP, donde la cámara térmica adelantó la emergencia de brotes en 12 días, con respecto al cantero. Las tasas de multiplicación de plántulas por cormo y por m2, fueron influenciadas significativamente (p < 0.05) por BAP, TC y AP. Con BAP se produjo un 30 y 31% de incrementos de TM por cormo y por m2, respectivamente, en comparación al tratamiento sin BAP. Dentro de la cámara térmica la TM por cormo y por m2 se incrementó en un 44% con respecto al cantero. En cuanto al efecto del TC, los resultados indicaron una TM por cormo directamente proporcional al tamaño del cormo. Por el contrario, la TM por m2 mostró un comportamiento inversamente proporcional al tamaño del cormo. Se recomienda utilizar cámara térmica y BAP para masificar la producción de plántulas de plátano vía macropropagación.
