Publication Date:

In this paper we analyze innovative nursery and field techniques oriented to reduce outplanting stress. In the nursery, the main research lines are directed towards improving seedling quality, especially its resistance to water stress, by means of the use of containers gauged to the different root growth patterns of the species, the use of hydrogel to improve the water holding capacity of the substrate and reduce post-planting stress, the use of drought preconditioning to induce mechanisms for drought resistance, the use of fertilization according to field conditions and target seedlings for restoration projects and the use of growth regulators to control the biomass distribution within the seedlings.
