The objective was to study the growth resp onses, survival and photos ynthetic response during the acclimatization of plants maintained on three different substrates (Plantmax forestry ® , sand and 1:1 Plantmax forestry ® and sand) under three shading conditions ( 50% red and blue shading nets and control without shading nets). The highest le af and shoot numbers per plant and survival rate we re observed in treatments with the Plantmax forestry ® type substrate in the absence of shading. In vitro culture plants behaved similarly or better than rhiz ome propagated control plants with regard to the net photosynthesis rate, carboxylation efficiency, stomatal conductance and transpiration rate. In general, for both conditions, in vitro and control plants had similar efficiency of bi ochemical functions and of photosystem II. These results show that plants derived from in vitro culture exhibit satisfactory physiological yield and greenhouse acclimation capacity. 2015 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303042425013 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
