Plant evaluation of Eucalyptus grandis Hill Ex Maiden to 60 months of plants in containers obtained with different substrates and irrigation of hardening

Abstract

An integrated diagnostic site allows greater precision in the identification of possible constraints and possibilities presented by a plantation. The lack of sufficient and appropriate to serve as the basis for developing a productive reforestation represents perhaps one of the major constraints to the development of high yield with Eucalyptus grandis. Plant evaluation of eucalyptus grandis hill ex maiden to 60 months of plants in containers obtained with different substrates and irrigation of hardening is the objective of this work. Planting was done at the Botanical Garden of the province of Pinar del Río. This was evaluated over a period of 60 months through various morphological, physiological and soil and climate. It was found that the highest values of survival in the early stages of the plantation are mainly for those plants that were subjected to moderate levels of hardening, the plants of Eucalyptus grandis container obtained with different substrates and risk of developing hardening best presented are tho se obtained in the substrate 2 with strong and moderate water (S2R2 y S2R3) of hardening.
