Low-Temperature Effects on Photosynthesis and …

A) sunlight concentration B) temperature C) chlorophyll concentration D) carbon dioxide availability Effects of the variables and there concentrations: The amount of sunlight will decide the rate of photosynthesis as there will be a an increased rate of photosynthesis due to the increased availability of photons of light....

Effects of low temperature on photosynthesis

The quantum yield of PSⅡelectron transport (ΦPSⅡ), photochemical quenching (qP),and apparent photosynthetic electron transfer rate (ETR) of chrysanthemum leaves decreased with increasing stress and time, and recovered quickly after the release of lower temperature and weaker light stress but more slowly after the release of critical low temperature and weak light stress.

The Effect of Low Night and High Day Temperatures on Photosynthesis in Tomato

Under the stress of lower temperature and weaker light, the net photosynthetic rate (Pn) and stomatal limitation (Ls) of chrysanthemum leaves decreased while the intercellular CO2 concentration (Ci) increased, the maximal photochemical efficiency of
PSⅡ(Fv/Fm) in dark and the initial fluorescence (Fo) had no obvious change, but the maximal photochemical efficiency of PSⅡ (Fv'/Fm′) in light increased after an initial decrease.
