Abstract
Conduziu-se este trabalho, com o objetivo de induzir a estímulo do comportamento fotoautotrófico durante o enraizamento in vitro em brotações de Annona glabra L. Brotações oriundas de cultivo em tubos fechados com tampa e película de PVC (cultivo sem aeração), com tampa sem a película de PVC e tampão de algodão (cultivo com aeração) foram inoculadas em meio WPM suplementado com 4,9 µ M de AIB e 164,4mM de carvão ativado na presença (58,42mM) ou ausência de sacarose. Durante o enraizamento, foram mantidas as mesmas condições de vedação dos tubos de ensaio em que as brotações foram induzidas. Após a inoculação, os tubos contendo os explantes foram mantidos em sala de crescimento sob radiação fotossintética ativa de 45-56 µ mol.m-2.s-1 a 25±3ºC. Os resultados mostraram que o enraizamento das brotações de A. glabra não dependeu do suprimento de sacarose no meio de cultura, em tubos fechados com o tampão de algodão ou tampa plástica sem PVC. A aeração dos tubos de ensaio trouxe incrementos de significativos (até 250%) na matéria seca radicular. A indução de raízes secundárias (laterais) em A. glabra só ocorreu em culturas com aeração, independentemente da presença ou ausência de sacarose no meio de cultura. Com os resultado desse experimento, conclui-se que o estímulo do comportamento fotoautotrófico em A.glabra pode ser obtido com sucesso durante a fase de enraizamento in vitro.
The objective of the present work was to evaluate whether Annona glabra L. shoots are able to acquire the photoautotrophic behavior during the in vitro rooting. In vitro A. glabra shoots originated from cultures in vessels sealed with cap and PVC film (culture without aeration), cap without PVC film or cotton tampon (cultures with aeration), were inoculated in WPM medium supplemented with 4.9 µ M IBA and 164,4mM activated charcoal in the presence (58.42mM) or absence of sucrose. During rooting, the same conditions in which shoots were induced were maintained. After inoculation, the tubes with explants were maintained in growth room under photosynthetic active radiation of 45-56 µ mol.m-2.s-1 and of temperature 25±3ºC. The results showed that the rooting of A. glabra shoots do not depend on the supply of sucrose into culture medium, in vessel with aeration. Aeration of cultures brought expressive increments of dry weight of roots (up to 250%). The induction of secondary (side) roots was found only in cultures with aeration, independently of sucrose presence. One concluded that the acquisition of the photoautotrophic behavior in A. glabra may be obtained with success during the in vitro rooting phase.
