| Research on anatomical modifications under in vitro culture is essential to the definition and understanding of the development of micropropagated plants. Likewise, such research is essential to improve the steps of the acclimatization process. Accordingly, the objective of the present study is to verify the differences in the leaves anatomical traits of micropropagated orchids under calcium silicate concentrations. Seedlings of in vitro-germinated seeds, measuring 0.5 cm in length, were inoculated in 250 cm3 pots with 60 mL MS culture medium and different silicon concentrations (0, 0.5, 1.0 and 2.0 mg L-1) in different culture environments (natural environment, in a greenhouse and an artificial environment in a growth chamber) and in all statistical... |
