Agriculture and Forestry - Studies from Innsbruck University have provided new data on agriculture and forestry

  2010 SEP 2 - (VerticalNews.com) -- According to recent research published in the journal Tree Physiology, "Infrared differential thermal analysis (IDTA) was used to monitor the velocity and pattern of ice propagation and deep supercooling of xylem parenchyma cells (XPCs) during freezing of stems of Castanea sativa L., Morus nigra L. and Quercus robur L. that exhibit a macro- and ring-porous xylem. were conducted on the surface of cross- and longitudinal stem sections. ...read more


Agriculture and Forestry - Recent studies by N. Regier and co-authors add new data to agriculture and forestry findings

  2010 SEP 2 - (VerticalNews.com) -- According to recent research published in the journal Tree Physiology, "Trees need to store reserves to allow their survival during winter and for bud flush and leaf growth in the following spring. In many tree species, these reserve functions are mainly covered by starch, which is degraded to soluble carbohydrates during the dormant season for maintenance respiration and in spring during bud flush. ...read more


Agriculture and Forestry - Investigators at Duke University have published new data on agriculture and forestry

  2010 SEP 2 - (VerticalNews.com) -- According to recent research published in the journal Tree Physiology, "Anatomical and physiological acclimation to water stress of the tree hydraulic system involves trade-offs between maintenance of stomatal conductance and loss of hydraulic conductivity, with short-term impacts on photosynthesis and long-term consequences to survival and growth. Here, we study the role of variations in root and branch maximum hydraulic specific conductivity (k(s-max)) under high and low soil moisture in determining whole-tree hydraulic conductance (K-tree) and in mediating stomatal control of gas exchange in four contrasting tree species growing under ambient and elevated CO2 (CO2a and CO2e). ...read more
