Estimulation of autotrophy in in vitro plantlets could be achieved through changes in the culture medium, or by changing the traditional hermetic caps by one that could allow gas exchanges between the culture and the environment. Besides that, the use of lamps with distinct emission spectrum irradiaction has propitiated successful results. This work was carried out aiming to evaluate the either the combined or the single action of some factors that can induce autotrophy on in vitro A. andraeanum cv. Eidibel plantlets. 3 sucrose concentrations were used: 0, 15 and 60 mM and for each one, to kinds of flasks according to the cap ventilation: under (0.038 L.h-1) and without ventilation. Flasks were kept under cold light fluorescent lamps or under gro-lux lamps. At the end of the experiment showing the highest shoot dry mass treatment was 60 mM, under ventilation and gro-lux, and the treatment which accumulate root dry mass to a lesser extent were 0 mM with ventilation and cold light and 15 mM without ventilation and cold light. In average, treatments with higher sucrose content in the culture medium, that is, 60 mM, under gro-lux lamps, presented the highest chlorophyll a, b and total contents, than those under cold lamp. Steps of carbohydrates metabolism could be associated with the total soluble sugars (sucrose and reducing sugars) levels, highlighting the steps where nutrient requirements were higher, showing the role of the plantlets sink. Monitoramento do final da fase in vitro de plântulas de Anthurium andraeanum. O estímulo à autotrofia em plântulas in vitro pode ser alcançado através de mudanças no meio de cultura, ou pela troca de tampas herméticas por tampas que permitam a troca de gases entre a cultura e o ambiente. Além disso, o uso de lâmpadas com distintos espectros de irradição tem propiciado bons resultados. Este trabalho foi conduzido com o objetivo de avaliar a ação isolada ou em conjunto de fatores que podem induzir a autotrofia em plântulas de A. andraeanum vc. Eidibel in vitro. 3 concentrações de sacarose foram usadas: 0, 15 e 60 mM e para cada concentração foram empregados frascos com ventilação (0,038 L.h-1) ou sem ventilação. Os frascos foram mantidos sob lâmpada fluorescente fria ou gro-lux. O final dos experimentos mostrou que o maior acumulo de massa seca da parte aérea ocorreu a 60 mM, sob ventilação e gro-lux, e os tratamento que acumularam menor massa seca de raízes foram 0 mM com ventilação e sob luz fria e 15 mM sem ventilação e luz fria. Em média, os tratamentos com o maior teor de sacarose no meio, 60 mM, sob lâmpada gro-lux, apresentaram as maiores concentrações de clorofila a, b e total, do que sob luz fria. Os níveis de açúcares solúveis totais (sacarose e açúcares redutores) mostraram passos do metabolismo de carboidratos nessas plantas, realçando os momentos em que a exigência por nutrientes foi maior, destacando-se o papel de dreno das plântulas
