Open AccessInterannual radial growth response of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) to severe droughts: an analysis along a gradient of soil properties and rooting characteristics
We analyzed stem growth responses of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) to severe drought in 2003/04 and 2018. The results showed high drought tolerance in sandy, loamy, and most silty soils, with...

Climate and seasonal rainfall anomalies along an elevational gradient in the El Sira Mountains, Peru, and their impacts on tree radial growth
The explicit purpose of this study was to characterize climate and vegetation along the western slope of the El Sira Mountains (Peru) and evaluate radial tree growth in response to seasonal rainfall anomalies....

Open AccessEnvironmental control of daily stem radius increment in the montane conifer Cedrus libani
Growth response of conifers is species- specific and depends on site and climate conditions. Studies on daily radial stem growth use different analytical approaches to determine species reactions to environmen...

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...

Open AccessCambial activity and xylogenesis in stems of Cedrus libani A. Rich at different altitudes
The dynamics of cambial activity and xylogenesis provide information on how and to what extent wood formation respond to climatic variability. The Lebanon Cedar (Cedrus libani A.Rich) is a montane tree species wh...

Role of Photosynthetic Induction for Daily and Annual Carbon Gains of Leaves and Plant Canopies
Although quite a body of literature exists on carbon gains by plant canopies, the methodology for determination of crown carbon balances of individual plants is very limited. Similarly, little is known about t...

Spatial and temporal variability of soil water in drylands: plant water potential as a diagnostic tool
Arid and semi-arid regions are characterized by low rainfall and high potential evaporative demand. Here, water is the major limiting factor for plant growth and productivity. Soil and surface hydrology proper...

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 gas exchange of beech (Fagus sylvatica L.) seedlings in lightflecks: A system for measuring rapid changes in CO2 partial pressures
A system is described for the measurement of fast transient responses of leaf gas exchange to lightflecks. Any chamber adulterates a true signal unless in the steady-state; therefore, a procedure for estimatin...
