    Photosynthetic characteristics and simulation of annual leaf carbon gains of hybrid poplar (Populus nigra L. × P. maximowiczii Henry) and black locust (Robinia pseudoacacia L.) in a temperate agroforestry system

    A leaf net photosynthesis model is presented driven by light and modulated by temperature and air humidity. From this the seasonal variation of CO2 uptake and release could be modelled to estimate the annual carb...

    Effects of leaf temperature on initial stomatal opening and their roles in overall and biochemical photosynthetic induction

    The more stomata affect photosynthetic induction courses, the stronger the influence of leaf temperature on the induction parameters becomes. Initial stomatal conductances relative to species-s...

    The effect of initial stomatal opening on the dynamics of biochemical and overall photosynthetic induction

    Initial stomatal conductance at onset of illumination and lag times before stomata start to open in response to light are decisive for the whole course of photosynthetic induction. Neglecting these effects can...

    Intra-annual stem growth dynamics of Lebanon Cedar along climatic gradients

    Onset of cambial activity in Lebanon Cedar is triggered by stem temperature but may be delayed by high site-LAI. Higher growth rates and tree-ring widths were observed under better water and li...

    Loss of quantum yield in extremely low light

    It has generally been assumed that the photosynthetic quantum yield of all C3 plants is essentially the same for all unstressed leaves at the same temperature and CO2 and O2 concentrations. However, some recent w...

    Sucrose phosphate synthase in leaves of mistletoe: its regulation in relation to host (Abies alba) and season

    Sucrose-phosphate synthase (SPS; E.C. 2.4.1.14) was studied in 1-year-old leaves of the xylem-parasitic mistletoe (Viscum album L.), growing on Abies alba. Glucose-6-phosphate served as an allosteric activator o...

    Impacts of urban storm-water drainage channels on a northern Australian mangrove forest

    A common practice in tropical mangrove forests is to widen, deepen or extend the natural channels, or create new channels, in order to increase drainage to limit mosquito breeding habitats. Such excavations w...

    Leaf conductances and xylem pressures of the host/mistletoe pair Eucalyptus behriana F. Muell. and Amyema miquelii (Lehm. ex Miq.) Tiegh. at permanently low plant water status in the field

    Over several days at permanently low plant water status in the field, where predawn xylem pressures (Ψ) were never higher (less negative) than −1.2 MPa even after extended rain, leaf conductances (g) and trans...

    Leaf gas exchange of beech (Fagus sylvatica L.) seedlings in lightflecks: effects of fleck length and leaf temperature in leaves grown in deep and partial shade

    Responses of leaf gas exchange in shade and half-shade grown seedlings of the European beech, Fagus sylvatica L., to constant light conditions indicate different phases of photosynthetic induction: an immediate, ...

    Carbon discrimination, water-use efficiency, nitrogen and phosphorus nutrition of the host / mistletoe pair Eucalyptus behriana F. Muell and Amyema miquelii (Lehm. ex Miq.) Tiegh. at permanently low plant water status in the field

    Under conditions where both plants had permanently low water status, the mistletoe, Amyema miquelii (Lehm. ex Miq.) Tiegh., had lower nitrogen contents in leaf tissue than its host, Eucalyptus behriana F. Muell. ...

    Changes in Plant Ecophysiology Across a Central European Hedgerow Ecotone

    In past decades, ecological research often concentrated on processes and patterns of homogenous ecological systems. This research produced important estimates of primary production, standing crop, nutrient cyc...
