Developing management practices that make more efficient use of irrigation is important for improving the sustainability of nursery crop production. Integrating refined irrigation scheduling with a substrate amendment like biochar can improve irrigation efficiency. The objective of this research...

* Under prolonged drought and reduced photosynthesis, plants consume stored nonstructural carbohydrates (NSCs). Stored NSC depletion may impair the regulation of plant water balance, but the underlying mechanisms are poorly understood, and whether such mechanisms are independent of plant water...

The genus Pinus has wide geographical range and includes species that are the most economically valued among forest trees worldwide. Pine needle length varies greatly among species, but the effects of needle length on anatomy, function, and coordination and trade-offs among traits are poorly...

World-wide, forests are experiencing drought-induced mortality. However, physiological adaptation to drought is highly variable, which may lead to differential mortality patterns and alter community structure. In this study, saplings of four common tree species (Ormosia pinnata, Dalbergia odorifera...

Background and Aims: Allometric scaling between stomata and xylem for terrestrial woody plants is a widely observed pattern that may be constrained by water transport. Floating-leaved plants, a particular life form of aquatic plants, have leaves in direct contact with both air and water and a...

Background and Aims: By the year 2100, atmospheric CO₂ concentration ([CO₂]_a) could reach 800 ppm, having risen from ∼200 ppm since the Neogene, beginning ∼24 Myr ago. Changing [CO₂]_a affects plant carbon-water balance, with implications for growth, drought tolerance and vegetation shifts. The...

Leaf traits, the rate of gas exchange, and biomass were examined in five plurizonal species (Alisma plantago-aquatica L., Carex acuta L., Eleocharis palustris (L.) Roem. et Schult., Phalaris arundinacea L., and Typha angustifolia L.) of emergent plants growing in wetlands of forest (Middle Urals)...

The effects of drought stress, Phytophthora cinnamomi infection and their interaction on water relations and growth were examined for 28 days on two year-old potted trees of Eucalyptus obliqua (L'Hér.). There were significant effects of drought stress on plant photosynthesis, stomatal conductance,...

Background: Salinity tolerance of Ficus carica L. is still poorly quantified. Objectives: We subjected container-grown fig plants (cv. 'Dottato') to salt stress to determine survival, growth, biomass distribution, leaf gas exchange, and water relations. Methods: In a typical experiment plants were...

Internal water storage in the stem provides additional water for transpiration and photosynthesis and thus ensures tree hydraulic safety and growth under stressed conditions. Comprehensive understandings in elevation- and species-specific patterns of stem water relations and the underlying...
