Response of five temperate deciduous tree species to water stress.
Gas exchange, tissue water relations, and leaf/root dry weight ratios were compared among young, container-grown plants of five temperate-zone, deciduous tree species (Acer negundo L., Betula papyrifera Marsh, Malus baccata Borkh, Robinia pseudoacacia L., and Ulmus parvifolia Jacq.) under well-watered and water-stressed conditions. There was a small decrease (mean reduction of 0.22 MPa across s...
متن کاملStem water storage in five coexisting temperate broad-leaved tree species: significance, temporal dynamics and dependence on tree functional traits.
The functional role of internal water storage is increasingly well understood in tropical trees and conifers, while temperate broad-leaved trees have only rarely been studied. We examined the magnitude and dynamics of the use of stem water reserves for transpiration in five coexisting temperate broad-leaved trees with largely different morphology and physiology (genera Fagus, Fraxinus, Tilia, C...
متن کاملWater storage capacitance and xylem tension in isolated branches of temperate and tropical trees.
Trees of tropical semi-deciduous forests range from "drought-avoiding" stem-succulent species with low-density wood (< 0.5 g cm(-3)), which maintain high stem water potentials (psi(STEM) > -0.7 MPa) throughout the year, to "drought-tolerant" deciduous hardwood species (wood density > 0.75 g cm(-3)), which dehydrate strongly during seasonal drought (psi(STEM) < -6 MPa). In stem-succulent and oth...
متن کاملAN ANATOMICAL STUDY OF FIVE POLYSTICHUM SPECIES IN IRAN
In this research, five species of genus Polystichum, belong to Aspidiaceae, namely, P. lonchitis, P. woronowii, P. setiferum, P. braunii and P. aculeatum, gathered from Gilan and MazandaranProvinces were anatomically studied. To distinguish anatomical character of different growing organs such as pinnules, rachis, rhizumes and roots, the cross section was prepared. Based on these researches, id...
متن کاملInvestigating xylem embolism formation, refilling and water storage in tree trunks using frequency domain reflectometry
Trunks of large trees play an important role in whole-plant water balance but technical difficulties have limited most hydraulic research to small stems, leaves, and roots. To investigate the dynamics of water-related processes in tree trunks, such as winter embolism refilling, xylem hydraulic vulnerability, and water storage, volumetric water content (VWC) in the main stem was monitored contin...
