Contribution of in vitro flowering to the knowledge of reproductive development in higher plants
In vitro flowering studies can contribute to the understanding of some of the mechanisms involved in reproductive development, in particular those related to vernalization and photoperiodism. However, on account of the excision of plant parts, in vitro studies imply the rupture of correlation phenom...

El análisis del comportamiento in vitro de plantas a día corto (PDC) y largo (PDL), con o sin requerimientos de vernalización, y el de algunas plantas indiferentes (PI) permiten arribar a las siguientes conclusiones generales: a) Las exigencias de vernalización y fotoperiodismo son idénticas a las requeridas por la planta in vivo; b) En las mismas categorías, especies con aparente preexistencia de potencial de floración a nivel de ápices caulinares; inhibición por presencia de tejidos u órganos acompañantes; posibilidad de floración bajo periodos no inductivos in vitro; c) Capacidad de yemas neoformadas en la captación del estímulo de floración; d) Frecuencia de la reversión o pérdida de la inducción floral in vitro;e) Inhibición de la floración in vitro por acción auxínica.

In vitro flowering studies can contribute to the understanding of some of the mechanisms involved in reproductive development, in particular those related to vernalization and photoperiodism. However, on account of the excision of plant parts, in vitro studies imply the rupture of correlation phenomena, which can influence the expression of flowering. The following general conclusions can be drawn from the analysis of the in vitro behavior of short and long day plants, either with or without vernalization requirements, and of some photoperiodically indifferent plants: a) Photoperiod and vernalization requirements of explants are identical to those of plants in vivo; b) In some cases, flowering in vitro can be achieved under non-inductive photoperiods; c) Buds developed in vitro are capable of sensing the floral stimuli; d) There is frequent loss of floral induction in vitro; e) Auxins inhibit flowering in vitro.
