Advances in vegetative propagation of Olive tree

Abstract In Brazil, there is a growing interest in the crop of the olive tree, especially in those regions considered suitable for cultivation, where low temperatures occur between 8ºC and 10ºC in the period before flowering. The areas with these characteristics are located mainly in the South and Southeast regions of the country, characterized by a temperate climate in function of altitude, with the occurrence of natural vernalization. The propagation is an integral part of the production chain and the first step towards the implantation of the olive tree crop or renovation of the existing orchards. Obtaining quality seedlings, besides guaranteeing uniformity and reliable varietal origin, is a factor that influences the whole life of the orchard, allowing to maximize the effects of climate and soil and mainly of crop treatments adopted for the culture. In the Laboratory of Propagation of Fruit Plants of the Department of Phytotechnology of the Eliseu Maciel School of Agronomy of the Federal University of Pelotas, we have sought to research micropropagation and minipropagation allied to the clonal gardens kept in a protected place, reducing the physical space and improving, mainly, the crop protection control. Olive tree seedlings propagated by different methods of asexual propagation, such as micropropagation, microcutting and minicutting, and they have their completion until the complete development in no-soil cultivation systems.
