Gas exchange attributes like net CO2 assimilation rate (A), transpiration rate (E), sub-stomatal conductance (Ci), stomatal conductance (gs), water use efficiency (A/E) and (Ci/Ca) from 11:00 am to 1:00 pm.
Net CO2 assimilation rate (A) of both wheat cultivars (S-24 and PARI-73) reduced significantly under saline conditions.
Photosynthetic efficiency is usually determined by measuring CO2 assimilation by leaves in the light but can also be determined by measuring the extent of chlorophyll fluorescence in leaves that have been kept in the dark (Yang et al.
Although there are several studies about the midday depression in CO2 assimilation in field crops (Wang et al.
Changes in CO2 assimilation may be attributable to either stomatal or non-stomatal factors or both.
Leaf CO2 assimilation rate (Pn), transpiration rate (Tr), stomatal conductance (gs) and intercellular CO2 concentration (Ci) were measured, and the instantaneous carboxylation efficiency (Pn/Ci) was calculated.
The photosynthesis rate, CO2 assimilation rate, and stomatal conductance in response to Cd and Pb heavy metals have been well documented (Chen et al.
In addition, salinity markedly reduces water potential in cells leading to closure of stomata and limits net CO2 assimilation rate (Munns et al.
Root-medium applied NaCl significantly reduced net CO2 assimilation and transpiration rates in all cotton cultivars.
Reduction in leaf CO2 assimilation rate is a common effect of salinity stress.
