Abstract
Due to its fast growth and fibre properties, in particular high pulp quality, Eucalyptus globulus L. is one of the most commonly planted hardwood trees in Portugal. Although widely distributed, its expansion is mostly restricted by its drought and cold sensitivity. To overcome these limitations, development of breeding programs requires detailed physiological information of the stress-response of the clones selected for nursery production. In addition, such information is necessary for further selection and to support decisions to allocate clones to different climatic regions.
Considering that resistance of plants to drought and low temperatures share common mechanisms, the aim of the present work was to investigate whether the two clones with contrasting response to drought also exhibit differences (growth and metabolic) in response to chilling.
We analyzed the effect of water deficit and gradual temperature decrease on morphological parameters, leaf pigments, membrane lipid composition, as well as on osmotic potential, osmotically active compounds and enzymes with antioxidant activity in leaves and roots of both clones.
