Nowadays, fruit trees constitute an inexhaustible source of wealth, not only for its acceptance in various regions of the world but also for the nutrients they contribute to human health. Fruit tree populations are very low all over the world; even they are sometimes almost inexistent, since these cultivated areas are poorly attended, besides their weak genetic variability and hard propagation, as a result of the specific characteristics of many of these species. The natural propagation of woody fruit species is usually by seeds, which are often released in small amounts and strongly damaged by pests and predators; therefore, it is a limiting factor for obtaining future planting material. Biotechnological techniques can play an important role for the adequate supply of vitroplants as planting material. In vitro germination makes this process possible under aseptic and controlled conditions at any season of the year, enabling to reduce germination process and obtain seedlings under appropriate phytosanitary conditions for in vitro culture studies. However, for the successful establishment of these species, it is necessary to prevent and control microbial contamination and phenolic oxidation, as it is one of the most serious problems in woody fruit tree micropropagation.

Keywords : fruit trees; microbial contamination; phenolic oxidation; in vitro culture.
