The plant elicitors use as an agricultural input is limited and few studies show their influence on physiological responses. However, its can induce broad-spectrum long-lasting resistance in plants by inducing defense systems, primary secondary metabolism. the aim of this study was to evaluate gas exchange (gs, A, E, Ci, WUE, iWUE iCE) enzymatic antioxidant system (POD, PPO PAL) Z. mays under a...

The effects of root temperatures (25, 35 and 45°C) and temperature duration (30, 60 and 90 min) on net photosynthesis rate, stomatal conductance and transpiration rate in Tradescantia pallida were investigated. The experiment was conducted under controlled conditions with factorial arrangement based on a completely randomized design (CRD) and four replications. Result showed that, net photosynt...

Salinity tolerance in plant species varies widely due to adaptation and acclimation processes at the cellular and whole-plant scales. In mangroves, extreme substrate salinity induces hydraulic failure and ion excess toxicity and reduces growth and survival, thus suggesting a potentially critical role for physiological acclimation to salinity. We tested the hypothesis that osmotic adjustment, a ...

Accurate simulations of terrestrial carbon assimilation and canopy transpiration are needed for both climate modeling and vegetation dynamics. Coupled stomatal conductance and carbon assimilation (A gs) models have been widely used as part of land surface parameterizations in climate models to describe the biogeophysical and biogeochemical roles of terrestrial vegetation. Differences in various...

The availability of commercially available portable photosynthesis systems has facilitated widespread photosynthetic research. Our study aimed to evaluate the reliability a recently developed inexpensive system, Yaxin-1105, in measuring gas exchange rice (Oryza sativa L.) leaves. Gas parameters, including net rate (Anet), stomatal conductance (gs), intercellular CO2 concentration (Ci), and tran...

Advanced lines of Pima cotton {Gossypium barbadense L.) bred for higher yield potential and heat resistance have higher stomatal conductance and smaller leaf areas than those of obsolete !ines. In controlled experiments, five commercial lines of Pima cotton having increasing lint yield and heat resistance showed a gradient of increasing stomatal conductance and decreasing leaf size. In field ex...

Plants exchange greenhouse gases carbon dioxide and water with the atmosphere through the processes of photosynthesis and transpiration, making them essential in climate regulation. Carbon dioxide and water exchange are typically coupled through the control of stomatal conductance, and the parameterization in many models often predict conductance based on photosynthesis values. Some environment...

Sorghum bicolor (L.) Moench, one of the most important dryland cereal crops, is moderately tolerant soil salinity, a rapidly increasing agricultural problem due to inappropriate irrigation management and salt water intrusion into crop lands as result climate change. The mechanisms for sorghum’s tolerance high salinity have not been elucidated. This study tested whether sorghum plants adapt stre...
