“…A transpiração e o consumo de água das duas espécies estão apresentados no quadro 1. O E. saligna teve maior transpiração e consumiu mais água diariamente que o E. grandis no T1, em ambas as épocas de semeadura (Quadro 2), o que está relacionado com a maior área foliar encontrada nesta espécie (Whitehead & Breadle, 2004). No T2 da primeira época de semeadura, o Eucalyptus saligna apresentou transpiração e consumo de água similares aos de E. grandis, diferentemente da segunda época de semeadura no T2, quando o E. saligna teve uma transpiração e consumo de água menores do que os do E. grandis.…”

“…(planted on more than 1 Mha in the Iberian Peninsula [52]) revealed low frost tolerance. This trait, along with water stress resistance, are the main factors that restricting crop areas because their plantations are limited to sites where minimum temperatures usually do not fall below -5 • C [40,45,47,59]. …”

-Eucalyptus globulus is widely used in productive exotic plantations but the expansion of these plantations is limited by low temperatures, as its cold hardening capacity is limited (0.5 to 3.0 • C). It is not well understood how nursery fertilisation affects the field performance of plants. This led us to study the effect of three mineral nutrients (N, P and K) on both plant quality and frost tolerance. The experiment comprised eight growth treatments in which a high dose (H-) or a low dose (L-) of each nutrient was applied. Nitrogen was the nutrient that determined shoot growth, new root growth after transplanting (root egress), frost tolerance and field performance. Performance was better with treatment H-N than with treatment L-N, leaf nitrogen contents being 1.53 and 0.89% respectively. The effects of phosphorus and potassium were not significant between treatments for any parameter. The exception was P which, when interacting with N, favoured root egress for the H-N treatment. It was concluded that nursery fertilisation offers a management tool for eucalyptus growers concerned with plant stock quality.field performance / frost tolerance / mineral nutrients / non-structural carbohydrates / root egress Résumé -La fertilisation en pépinière affecte la tolérance au froid et la qualité des plants bouturés d'Eucalyptus globulus Labill. Eucalyptus globulus est largement utilisé dans des plantations exotiques productives, mais l'expansion de ces plantations est limitée par les basses températures, étant donné que l'endurcissement potentiel au froid de cette espèce est limité (0,5 à 3,0 • C). On ne comprenait pas bien comment la fertilisation en pépinière pouvait affecter la performance en plantation des plants. Ceci nous a amené à étudier l'effet de trois nutriments minéraux (N, P et K) sur la qualité des plants et la résistance au froid. L'expérimentation a comporté huit traitements pour l'étude de la croissance pour lesquels une forte dose (H-) ou une faible dose (L-) de chaque nutriment a été apportée. L'azote a été le nutriment qui a déterminé la croissance de la pousse, la croissance de nouvelles racines après transplantation (émission de racines), la résistance au froid et la performance en plantation. Les performances étaient meilleures avec le traitement H-N que avec le traitement L-N, la teneur en azote des feuilles atteignant respectivement 1,53 et 0,89 %. Les effets du phosphore et du potassium n'ont été significatifs pour aucun des paramètres. L'exception a concerné le phosphore qui lorsqu'il était en interaction avec l'azote a favorisé l'émission de racines dans le traitement H-N. On conclut de cette étude que la fertilisation en pépinière offre un outil de gestion pour les producteurs d'eucalyptus confrontés au problème de la qualité des plants.performance en plantation / tolérance au froid / nutriments minéraux / hydrates de carbones non structuraux / émission de racines

“…Conversely, Urograndis, which was selected in a null water deficit area, had the lowest Ψ value in the dry season. The lowest ψ md observed in an individual measurement was -4.2 MPa for a Urograndis sample, which is an extremely low value for Eucalyptus BEADLE, 2004). According to , rainfall at the site of origin of the different Eucalyptus species has a direct effect on traits related to water stress tolerance such as turgor loss point.…”

“…High productivity forests may accumulate biomass very quickly but will also transpire large amounts of water BEADLE, 2004). Furthermore, Eucalyptus plantations have relatively high leaf area indexes (LAI), often above five GIUNTI NETO et al, 2015), which elevates transpiration rates and increases the amount of rain intercepted by the canopy (BENYON; DOODY, 2015;BIALKOWSKI et al, 2015).…”
