Trabalho de conclusão de curso: cultivo in vitro de mirtileiro (Vaccinium virgatum Ait.), da cultivar delite com uso de TDZ e 2iP

Abstract

The blueberry is a species that belongs to the group of small fruits, it is a perennial plant and its fruits have a high concentration of antioxidants and anti-inflammatories. The propagation used commercially occurs in a vegetative way by cuttings, bringing risks to phytosanity. Thus, the in vitro cultivation of the species is a very well regarded alternative. In most of the studies presented, the research area focuses more on the cultivars of the highbush and lowbush groups, because they present higher commercial values, the species of the rabbiteye group, presents better adaptation to regions of temperate climate. Thus, this research was based on the use of a cultivar of the rabbiteye group, the "delite'' and aimed to study the behavior of the cultivar in the micropropagation of plants using different plant regulators. The results show that the combination of 2iP with TDZ, in the factors of number of leaves and number of shoots, had similar results when compared to zeatin, in the question of survival, there was no difference in the treatments, however the use of TDZ contributed to greater formation of callus. Thus, the use of TDZ with 2iP is effective for in vitro multiplication.
