Differential response of aspen and birch trees to heat stress under elevated carbon dioxide

Autor: Thomas D. Sharkey, David F. Karnosky, Joseph N.T. Darbah, Carlo Calfapietra

Publikováno v: Environmental Pollution. 158:1008-1014

The effect of high temperature on photosynthesis of isoprene-emitting (aspen) and non-isoprene-emitting (birch) trees were measured under elevated CO(2) and ambient conditions. Aspen trees tolerated heat better than birch trees and elevated CO(2) pro

The diurnal changes in light-saturated photosynthesis (Pn) under elevated CO(2) and/or O(3) in relation to stomatal conductance (g(s)), water potential, intercellular [CO(2)], leaf temperature and vapour-pressure difference between leaf and air (VPD(

The Scientific World Journal

Atmospheric CO2and tropospheric O3are rising in many regions of the world. Little is known about how these two commonly co-occurring gases will affect reproductive fitness of important forest tree species. Here, we report on the long-term effects of

Will photosynthetic capacity of aspen trees acclimate after long-term exposure to elevated CO2 and O3?

Autor: Lisa Rouse, Mark E. Kubiske, Joseph N.T. Darbah, Johanna Riikonen, Anu Sõber, Katre Kets, Neil D. Nelson, David F. Karnosky

Publikováno v: Environmental pollution (Barking, Essex : 1987). 158(4)

Photosynthetic acclimation under elevated carbon dioxide (CO2) and/or ozone (O3) has been the topic of discussion in many papers recently. We examined whether or not aspen plants grown under elevated CO2 and/or O3 will acclimate after 11 years of exp

Isoprene Emission and Carbon Dioxide Protect Aspen Leaves from Heat Stress

Autor: Thomas D. Sharkey, David F. Karnosky, Joseph N.T. Darbah

Publikováno v: Nature Precedings

High temperature, especially above 35oC, is known to reduce leaf photosynthetic rate in many tree species. This study investigated the effect of high temperature on isoprene-emitting (aspen) and non- emitting (birch) trees under ambient and elevated

Publikováno v: Environmental pollution (Barking, Essex : 1987). 155(3)

We studied the effects of long-term exposure (nine years) of birch (Betula papyrifera) trees to elevated CO(2) and/or O(3) on reproduction and seedling development at the Aspen FACE (Free-Air Carbon Dioxide Enrichment) site in Rhinelander, WI. We fou

Carbon gain and bud physiology in Populus tremuloides and Betula papyrifera grown under long-term exposure to elevated concentrations of CO2 and O3

Autor: Anu Sõber, Johanna Riikonen, Elina Vapaavuori, Karte Kets, Mark E. Kubiske, Elina Oksanen, Neil D. Nelson, Joseph N.T. Darbah, David F. Karnosky

Publikováno v: Tree physiology. 28(2)

Paper birch (Betula papyrifera Marsh.) and three trembling aspen clones (Populus tremuloides Michx.) were studied to determine if alterations in carbon gain in response to an elevated concentration of CO 2 ([CO 2 ]) or O 3 ([O 3 ]) or a combination o
