In vitro induction and culture of adventitious buds in epicotyl segments of sour orange

The objective of this work was to evaluate the induction and formation of adventitious buds in sour orange explants through the use of plant regulators. In vitro organogenesis experiments were conducted to evaluate the effect of BAP, TDZ, and KIN in different concentrations and under two light conditions; BAP and KIN, combined or not with NAA; BAP and KIN, separately or in combined concentrations. Sour orange epicotyl segments (1 cm length), from in vitro germinated plants, were used as explants. In order to induce bud formation, the explants were cultured in MT medium with or without the addition of plant regulators. The material was cultivated at 27ºC in the absence of light for 30 days, followed of culture under a 16-hour photoperiod. The experimental design was completely randomized, with four or five replicates, depending on the experiment; each replicate comprised one Petri dish with 20 explants. After 60 or 70 days of cultivation, the percentage of responsive explants and the number of buds were evaluated. The addition of BAP to the culture medium, combined or not with ANA, and in combinations with CIN, induces better organogenic response.

O objetivo deste trabalho foi avaliar a indução e a formação de gemas adventícias em explantes de laranja-azeda, pelo uso de fi torreguladores. Em experimentos de organogênese in vitro foram avaliados 6-benzilaminopurina (BAP), thidiazuron (TDZ) e cinetina (CIN), cem diferentes concentrações e sob duas ondições de luminosidade; BAP e CIN combinados ou não com ácido naftalenoacético (ANA); e BAP eCIN isoladamente ou combinados entre si. Segmentos de epicótilo de 1 cm de comprimento, provenientes de plântulas de laranja-azeda germinadas in vitro, foram utilizados como explantes. Para induzir a formação de gemas, os segmentos foram cultivados em meio MT com ou sem adição de fi torreguladores. O material foi cultivado a 27ºC em ausência de luz por 30 dias, seguidos de fotoperíodo de 16 horas. O delineamento experimental foi inteiramente casualizado, com quatro ou cinco repetições, a depender do experimento e, cadarepetição foi constituída de placa de Petri com 20 explantes. Após 60 ou 70 dias de cultivo foram avaliados o percentual de explantes responsivos e o número de gemas por explante. A adição de BAP ao meio de cultura,combinada ou não com ANA, e em combinações com CIN promovem melhor resposta organogênica.
