This study analyzed the vertical distribution of gravimetric water content (GWC), relative water content (RWC), and equivalent water thickness (EWT) in winter wheat during heading and early ripening stages, and evaluated the position of leaf number at which Vegetation Indexes (VIs) can best retrieve canopy water-related properties of winter wheat. Results demonstrated that the vertical distribu...

Rossby Wave Chromatography (RWC) is implemented in a linearized barotropic model as a tool to understand the response of the mid-latitude jet to external forcing. Given the background zonal-mean flow and the space-time structure of the baroclinic wave activity source, RWC calculates the space-time structure of the upper tropospheric eddy momentum fluxes. RWC is used to diagnose and understand t...

This study describes the physiological response of two co-occurring tree species (Eucalyptus marginata and Corymbia calophylla) to seasonal drought at low- and high-quality restored bauxite mine sites in south-western Australia. Seasonal changes in photosynthesis (A), stomatal conductance (g(s)), leaf water potential (ψ), leaf osmotic potential (ψ), leaf relative water content (RWC) and pressur...

Soybean is an important industrial crop in Croatia and in the last ten years (2000-2009) mean soybean harvested area was 45888 ha (from 35789 to 62810 ha) with average seed yield 2.0 t ha-1 (Central Croatian Bureau of Statistic, 2010). Seed yields of soybean varied in close connection with amount and distribution of precipitation during the vegetation period (Vučić and Bošnjak, 1980; Bošnjak, 2...

Context Several functions are used to describe the effects of soil water content on organic matter mineralisation. A meta-analysis published studies identified relative (RWC; available soil’s holding capacity) as best descriptor for N Aims To evaluate RWC a predictor C and mineralisation in New Zealand soils; investigate how solute diffusivity ‘Birch effect’ may help explain this relationship. ...

The goal of this research project was to determine the water transport behaviour of earlywood versus latewood in the trunk of 21-year-old Douglas-fir [Pseudostuga menziesii (Mirb.) Franco] trees. Specific conductivity (k(s)) and the vulnerability of xylem to embolism were measured on a single growth ring and in a subset of earlywood and latewood samples within the same ring. Earlywood/latewood ...

Drought stress is a key environmental factor limiting the growth and productivity of plants. The purpose of this study was to investigate the physiological responses of Camptotheca acuminata (C. acuminata) to different drought stresses and compare the drought tolerance between the provenances Kunming (KM) and Nanchang (NC), which are naturally distributed in different rainfall zones with annual...

The purpose of the work was to assess the combined effect of drought and salinity (50, 100, 200 mМ NaCl) on the mesoand ultrastructure of mesophyll cells of wheat seedlings. Stress development was estimated by a decrease in the relative water content (RWC) and CO2-dependent O2 evolution (An) in leaves. The decrease in the RWC and in An occurred rapidly in the absence of salt in the substrate an...

Tolerant and susceptible durum wheat varieties were grown in the 1 and 2 settlement zone under rainfed conditions inDaraa province-Syria, In order to expose plants to different level of water regime, since the two zones differ in total amount of rainfall during the growing season. Plants were suffered from terminal drought stress in both zones, however, the drought was more sever in the 2 settl...
