The spatial distribution of phosphate in the root system modulates N metabolism and growth in Eucalyptus grandis young plants
(Springer, 2017-02)
Key message: High P homogeneously applied in roots reduced growth and nitrate uptake. High P in a patch reduced N in tissues but did not reduce growth, because root hydraulic conductivity increased. Abstract: Little is ...
Changes in leaf stomatal conductance, petiole hydraulics and vessel morphology in grapevine (Vitis vinífera cv.Chasselas) under different light and irrigation regimes
(2017)
Hydraulic conductance and water transport in plants may be affected by environmental factors, which in turn regulate leaf gas exchange, plant growth and yield. In this study, we assessed the combined effects of radiation ...
Leaf and stem hydraulic traits in relation to growth, water use and fruit yield in Prunus avium L. cultivars
(Springer, 2013-07)
Physio-anatomical traits of rootstock have been considered as determinants of vigor in grafted plants. We evaluated how hydraulic traits of three Prunus avium cultivars grown on the same rootstock are related to tree growth ...
Physiological responses to alternative flooding and drought stress episodes in two willow (Salix spp.) clones
(National Research Council Canada-NRC Research Press, 2017-01)
Climate change will increase the occurrence of flash floods as a consequence of extreme rain events, creating alternate periods of drought and flooding during the growing season. We analyzed the responses of two willow ...
Extending the generality of leaf economic design principles in the cycads, an ancient lineage
(Wiley Blackwell Publishing, Inc, 2015-04)
Summary: Cycads are the most ancient lineage of living seed plants, but the design of their leaves has received little study. We tested whether cycad leaves are governed by the same fundamental design principles previously ...
Quality assessment of irrigation water under a combination of rain and irrigation
(Elsevier, 2015-09)
Supplementary irrigation is one of the proposed management practices to increase the area under grain production mainly in the Humid Pampas (HP). The most common source of irrigation water in the HP comes from groundwater ...
Glyphosate dynamics prediction in a soil under conventional and Nno-tillage systems during the crop cycle
(Sociedade Brasileira de Ciência do Solo, 2020-06)
Simulation models are efficient tools in order to predict the fate of different solutes in agricultural soils. The objectives of this work were to compare measured and predicted glyphosate and AMPA (its main metabolite) ...
Variation of wood density and hydraulic properties of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) clones related to a heat and drought wave in France
(Elsevier, 2009-01)
Drought response of three Douglas-fir clones (slow, intermediate and fast growing) inhabiting two different climatic regimes in France was examined.We used the hydraulic conductivity and the percent loss of conductivity ...
Cover crops effects on anisotropy of unsaturated soil hydraulic properties
(Elsevier, 2023-03)
No tillage (NT) is frequently implemented in simplified agricultural systems, which has negative effects on soil physical quality. Among the suggested practices to preserve the physical fertility of soils under NT are ...
Effect of cover crops on hysteresis and anisotropy of soil hydraulic properties
(Elsevier, 2022-12)
No till is the main management system for soil conservation world-wide. In Argentina is frequently implemented in simplified crop sequences, which has negative effects on soil physical quality (SPQ). Among the suggested ...
