The Arabidopsis thaliana ascorbate-deficient vtc-1 mutant has only 30% ascorbate contents of the wild type (WT). This was used here to study physiological roles under salt stress in vivo. Salt resulted a more significant decrease CO2 assimilatory capacity than WT. Photosystem II function also showed an increased sensitivity stress. Oxidative stress, indicated by hydrogen peroxide content, dramatically WT To clarify reason for oxidative mutant, small antioxidant compounds and activities...
The Watershed Allied Telemetry Experimental Research (WATER) is a simultaneous airborne, satellite‐borne, and ground‐based remote sensing experiment aiming to improve the observability, understanding, predictability of hydrological related ecological processes at catchment scale. WATER consists cold region, forest, arid region experiments as well hydrometeorology took place in Heihe River Basin, typical inland river basin northwest China. field campaigns have been completed, with an...
Abstract The study on the patterns of plant species diversity and factors influencing these forms basis ecology is fundamental to conservation biology. In this paper, desert soil properties (nutrient texture) were investigated along region Heihe River Basin (HRB) determine whether environmental influenced diversity. We found a total 44 shrub herb belonging 40 genera 17 families. largest family was Compositae, accounting for 25.0% total. Twenty‐four survey plots clustered into eight community...
Desert plants are zonal vegetation with unique functional traits and resource trade-offs in arid areas. The trade-off relationship among adversity strategies of desert play a key role their community construction. We investigated 16 leaf the dominant plants, including15 shrubs 11 herbs, Hexi Corridor from southeast to northwest, analyzed variation characteristics traits, responses soil properties at regional scale. results showed that bound water (BW), thickness (LT), carbon phosphorus ratio...
Abstract An automatic chamber (AC) is an alternative method to the eddy covariance (EC) technique for estimating of CO 2 fluxes. However, few direct comparisons between two techniques have been performed on nature alpine meadows. In order determine diurnal pattern net ecosystem exchange (NEE) in summer meadows, and test NEE measurement performance AC under site conditions, we conducted simultaneous measurements using both EC methods. The can be estimated with information from initial slope...
Light use efficiency (LUE) is a crucial determinant of plant productivity, while leaf functional traits directly affect ecosystem functions. However, it remains unclear how climate warming affects LUE and dominant species in alpine meadows. We conducted 4-year in-situ field experiment to investigate the eco-physiological characteristics for (Elymus nutans) common (Potentilla anserina) on Tibetan Plateau. The traits, photosynthesis fluorescence were measured, along with soil physical-chemical...
Identifying the mechanisms that underlie assembly of plant communities is critical to conservation terrestrial biodiversity. However, it seldom measured or quantified how much deterministic versus stochastic processes contribute community in alpine meadows. Here, we decay similarity with spatial and environmental distance Zoige Plateau. Furthermore, used redundancy analysis (RDA) divide variations relative abundance families into four components assess effects spatial. Species assemblage...
Haloxylon ammodendron (C. A. Mey), a C4 perennial woody species of the desert areas northwest China, is succulent xerophyte that has excellent adaptability to adverse arid environments. Our previous investigations showed sodium (Na+) positive effect on growth and drought resistance under conditions, which was closely related high Na+ accumulation in photosynthesizing stems (PS). In this study, we further investigated Na (as chloride, NaCl), Si silicic acid, H2SiO3) coexistence (NaCl + water...
Evaluating how decomposition rates and litter nutrient release of different types respond to changes in water conditions is crucial for understanding global carbon cycling. However, it unclear decreasing affects mixture interactions the maize-poplar system arid regions. Here, responses process agroforestry (control, light drought, moderate drought) were tested. Moderate drought significantly decreased rate poplar leaf mixed litters, was reduced maize straw stress. The mass loss litters...
The photosynthetic characters and water use efficiency of the desert plants Haloxylon ammodendron Calligonum mongolicum, which grow in conditions extreme stress, were studied. mechanisms their acclimation to harsh potential capacity for sand stabilizing are revealed. stable carbon isotope ratios (d 13C or 13C/12C) leaves assimilating shoots growing at southern edge Badain Jaran Desert analyzed by mass spectrometry compared. diurnal course net photosynthesis rate (Pn), Pn/light Pn/CO2 curves,...
Caragana korshinskii Kom. is a perennial xerophytic shrub, well known for its ability to resist drought. In order study ecophysiological responses of C. under extreme drought stress and subsequent rehydration, diurnal patterns gas exchange chlorophyll (Chl) fluorescence parameters photosystem II as Chl content were analyzed. Plant included (1) leaf abscission using stem photosynthesis, (2) improved instantaneous water-use efficiency, (3) decreased photosynthetic rate partly closed stomata...
Abstract Open-path eddy covariance systems are widely used for measuring the CO 2 flux between land and atmosphere. A common problem is that they often yield negative fluxes or physiologically unreasonable uptake in nongrowing season under cold conditions. In this study, a meta-analysis was performed on data from 64 FLUXNET sites relationship observed sensible heat analyzed. theory, these two should be independent of each other conditions (air temperature lower than 0°C) when photosynthesis...
