Deficit irrigation in Mediterranean vineyards - a tool to increase water use ef...

IHC - IS Viti&Climate: Effect of Climate Change on Production and Quality of Grapevines and their Products, 28 th, 2012 ; Water is increasingly scarce in Mediterranean Europe and irrigated agriculture is one of the largest and most inefficient users of this natural resource. Ecological topics such as the “water foot print” have become more relevant for the academy, consumers, governments and food industry. The...

Deficit irrigation in Mediterranean environment. What lessons have we learnt fr...

Libro de Actas - X Simposium Hispano Português de Relaciones Hidricas, 2010 ; Deficit irrigation techniques, implying that water is supplied at levels below full crop evapotranspiration throughout the growing season or in specific phenological stages, such as regulated deficit irrigation (RDI) or partial root drying (PRD), emerged as potential strategies to increase water savings with marginal decreases of yie...

Grapevine under deficit irrigation: hints from physiological and molecular data

Background - A large proportion of vineyards are located in regions with seasonal drought (e.g. Mediterraneantype climates) where soil and atmospheric water deficits, together with high temperatures, exert large constraints on yield and quality. The increasing demand for vineyard irrigation requires an improvement in the efficiency of water use. Deficit irrigation has emerged as a potential strategy to allow c...

Physiological and biochemical responses to low non-freezing temperature of two ...

Abstract – We have compared the metabolic responses of leaves and roots of two Eucalyptus globulus L. clones CN5 and ST51 that differ in their sensitivity to water deficits (ST51 is more drought sensitive), with regard to the effect of chilling (10/5 ◦C, day/night). We studied changes in growth, osmotic potential and osmotically active compounds, soluble proteins, leaf pigments, and membrane lipid composition. ...

Atividade anti-helmíntica de plantas em frangos de corte naturalmente infectado...

The anthelminthic activity of four plants - Allium sativum (garlic), Punica granatum (pomegranate), Tynnanthus labiatus (liana-carnation) and Cocus nucifera (coconut) with the activity of mebendazole - was compared. Seventy Hubbard chickens, naturally infected with Ascarídia galli, divided in 5 groups of 10 chichens plus a control group (not treated, n=20) were used in the experiment. The vegetable matter was u...

An Investigation into Mechanisms of Loss of Safe Basins in a 2 D.O.F. Nonlinear...

In this work we consider the transient stability of coupled motions of a 2 D.O.F. nonlinear oscillator that can represent, for example, the motions of a sea vessel under the action of trains of regular lateral waves. Instability is studied as the escape of the system from a safe potential well. The set of initial conditions in phase space that lead to acceptable motions constitutes its safe basin. We investigat...

NEPHROTOXICITY ATTRIBUTED TO MEGLUMINE ANTIMONIATE (GLUCANTIME) IN THE TREATMEN...

Background: Pentavalent antimonials have became of basic importance for the treatment of leishmaniasis. Their most severe side effects have been reported to be increased hepatic enzyme levels and electrocardiographic abnormalities. Nephrotoxicity has been rarely related. Observations: We report a case of generalized cutaneous leishmaniasis involving a 50-year old male patient who was submitted to treatment wit...
