“…Cristea (2010) mentions the usefulness of photoautotrophic micropropagation for the improvement of rhizogenesis and acclimatization process. Rohr et al (2003) discussed the morphological and anatomical anomalies of in vitrocultured plants, like the absence of cuticle and stomata that should protect the plantlets from desiccation, as well as the lack of a properly developed root system. They also mention the two main approaches used for ex vitro acclimation: reducing water stress and helping the plantlets become autotrophic.…”

“…Durante los 15 días dentro de la cámara bioclimática 100% de las plántulas sobrevivieron, algunas plantas mostraron elongación del tallo y emisión de brotes (Figura 1C). Resultados similares fueron reportados en fresa (Debnath, 2005) y en otros cultivos (Rohr et al, 2003). Después de remover la cobertura plástica, todas las plantas sobrevivieron durante siete días bajo sombreo (malla de 75%), sin presentar desarrollo aparente (Figura 1D).…”

“…Es conocido que la alta tasa de mortalidad en plantas obtenidas in vitro ocurre cuando las plantas están en ambiente controlado y son movidas a un ambiente no controlado (González et al, 2014) y esto particularmente ocurre cuando las plantas son transferidas a condiciones naturales (25.6 ±2 °C). Rohr et al (2003) indican que el mayor problema de supervivencia (SV) es la carencia de vigor de la planta y la necrosis de la plántula se debe a la excesiva pérdida de humedad por efecto de la temperatura durante la transferencia de plantas micropropagadas en condiciones in vitro (alta humedad relativa; HR) a condiciones ambientales con bajos niveles de HR.…”

“…Transplantation of in vitro-derived plants to soil is often characterized by lower survival rates. Before transfer of soil-rooted plants to their final environment, they must be acclimatized in a controlled environment room or in the glasshouse [24,25]. Plants transferred from in vitro to ex vitro conditions, undergo gradual modification of leaf anatomy and morphology, and their stomata begin to function (the stomata are usually open when the plants are in culture).…”
