Effects of diffuse radiation on canopy gas exchange ...

2008-5-13 · [15] In order to quantify the effect of diffuse radiation (R d) on carbon uptake we analyzed flux measurements at two nearby located forest sites that were exposed to almost identical weather conditions.Both sites had similar leaf area index (around 5–6 m 2 m −2), but differed in canopy structure.The Hainich site had an uneven-aged, multilayer canopy, while the Leinefelde site had an even ...

Flavonol 3‐O‐glycoside hydroxycinnamoyltransferases from ...

2005-3-3 · Flavonol 3-O-glucosides esterified with ferulic or p-coumaric acid at positions 3′′ and 6′′ are the major UV-B screening pigments of the epidermal layer of Scots pine (Pinus sylvestris) needles.The last steps in the biosynthesis of these compounds are catalyzed by enzymes that transfer the acyl part of hydroxycinnamic acid CoA esters to flavonol 3-O-glucosides.

Abstract. Both higher temperatures and increased CO 2 concentrations are (separately) expected to increase the emissions of biogenic volatile organic compounds (BVOCs). This has been proposed to initiate negative climate feedback mechanisms through increased formation of secondary organic aerosol (SOA).

Abstract. Emissions of volatile organic compounds (VOCs) by biogenic sources depend on different environmental conditions. Besides temperature and photosynthetic active radiation (PAR), the available soil water can be a major factor controlling the emission flux. This factor is expected to become more important under future climate conditions, including prolonged drying–wetting cycles.

A model of isoprene emission based on energetic ...

2002-1-4 · We present a physiological model of isoprene (2‐methyl‐1,3‐butadiene) emission which considers the cost for isoprene synthesis, and the production of reductive equivalents in reactions of photosynthetic electron transport for Liquidambar styraciflua L. and for North American and European deciduous temperate Quercus species. In the model, we differentiate between leaf morphology (leaf dry ...

Recent global decline of CO2 fertilization effects on ...

2020-12-11 · One source of uncertainty in climate science is how the carbon fertilization effect (CFE) will contribute to mitigation of anthropogenic climate change. Wang et al. explored the temporal dynamics of CFE on vegetation photosynthesis at the global scale. There has been a decline over recent decades in the contribution of CFE to vegetation photosynthesis, perhaps owing to the limiting effects of ...
