Última Changes in morpho-physiological attributes of Eucalyptus globulus plants in response to different drought hardening treatments Electron. J. Biotechnol. Coopman,Rafael E; Jara,Jorge C; Bravo,Leon A; Sáez,Katia L; Mella,Gloria R; Escobar,Rene. Morpho-physiological attributes exhibited in response to drought hardening at the end of the growing season of Eucalyptus globulus Labill under nursery conditions were studied to evaluate the effect of three drought hardening treatments in morpho-physiological traits used as suitable indicators of drought hardiness, such as, plant growth, root growth potential, plant water relationships and survival. Freezing resistance of drought hardened plants was also studied in order to evaluate cross hardening effects in cuttings of Eucalyptus globulus Labill. Drought hardening consisted in induced water stress by watering restriction, until plant stem xylem water potentials (Ψpd) reached to-0.2, -1.3 and -2.4 MPa. Two water stress-rewatering cycles were... Tipo: Journal article Palavras-chave: Freezing resistance; Root growth potential; Stem xylem water potential; Water stress; Water relationships.

J. Biotechnol. Coopman,Rafael E; Jara,Jorge C; Escobar,Rene; Corcuera,Luis J; Bravo,Leon A. Eucalyptus globulus Labill is one of the most planted species in Chile, because of its fast growth and superior pulp qualities. Nevertheless, the incidence of drought and frost damage immediately after planting is frequent. The purpose of this work was to study the effect of drought hardening on frost resistance and on variations in morphological traits that may increase drought resistance at nursery phase in four genotypes of E. globulus Labill. Drought hardening treatments consisted in induced water stress by watering restriction, until pre-dawn stem xylem water potentials (Ψpd) reached -0.2, -1.8 and -2.6 MPa. Two water stress-rewatering cycles were applied during 54 days of hardening. Plant and root biomasses were affected by the interaction...
