Response of Opuntia stricta Haw micropropagated plants in acclimatization and field
Journal Title: Biotecnología Vegetal - Year 2017, Vol 17, Issue 2
Abstract
Forage palm (Opuntia stricta Haw.) is a great important crop for the semi-arid region of Brasil. It has been propagated through in vitro culture, by areole activation. This work aimed to determine the response of Opuntia stricta Haw. variety ‘Oreja de Elefante Mexicana’ micropropagated plants during its acclimatization and field planting. Plants were acclimatized in tubes and plastic bags with a mixture of soil and manure, and it were kept in greenhouse for 130 days. Later, the plants kept in tubes were divided into nine treatments, according to their size (between 6 to 14 cm), and transfer to the field. The use of tubes provided a higher survival, height, fresh and dry mass of the cladodes. There was no significant differences between the recipients used for root development. At the end of acclimatization it was observed that plants did not have a uniform development, presenting size variation. After the first 15 days in the field, the majority of the plants with primary shoots were larger than 10 cm. At 60 days the survival was 100%, and all plants presented shoots, even the smallest. However, is recommended that plants larger than 10 cm will be used, due to the better establishment to field conditions. The results demonstrate the feasibility in the use of micropropagated plants for the establishment of forage palm fields.
