stomatal transpiration
1.STUDY ON THE RELATIONSHI BEWTEEN STOMATAL MOVEMENT AND TRANSPIRATION RATE OF MONGOLIA SCOTCH PINE
2.3 Both ABA contents of the leaves and [ABAxyl]L increased with the increase of exogenous pH buffer from 5 to 8, and pH value of xylem sap was raised when the maize were treated by pH buffer. At the same time , the stomatal conductance and transpiration rate decreased .
3.Effects of some lanthanide ions on K+ channels in guard cells and in mesophyll cells were investigated using whole-cell patch clamp technique, and influences of lanthanide ions on stomatal movements and transpiration were studied using epidermis biology analyse and other methods. We aim at posting some evidence to reveal rare earth elements might have potential practical values in regulating plant water status.
4.The results showed that photosynthetic rate, transpiration rate, and stomatal conductance decreased and leaf WUE increased with soil water content declined.
5.Antitranspirant A chemical that reduces transpiration. Antitranspirants may work by depositing a waterproof film over the stomata or by inducing stomatal closure.
6.The results showed that between two cultivars, the net photosynthetic rate, transpiration rate and grain yield were significantly different while stomatal conductance and WUE were not obviously different between two cultivars.
7.The content of chlorophyll (chlorophyll a and chlorophyll b), photosynthesis rate, transpiration rate, intercellular CO2 concentrations, and stomatal conductance was all reduced under water stress at different development stages.
8.The increase of water use efficiency under 7×10 -4 CO 2 is related to the increase of net photosynthetic rate and the decrease of transpiration caused by increased stomatal resistance.
9.The results showed that: ① The increase of leaf age resulted in the significant decrease of net photosynthetic rate(Pn), the transpiration rate (E), stomatal conductance(Gs), apparent quantum yield(AQY), CO_2 carboxylation efficiency(CCE) irrespectively of different tree species.
10.② In the condition of the same leaf age, the net photosynthetic rate(Pn), the transpiration rate (E), stomatal conductance(Gs),apparent quantum yield(AQY),CO_2 carboxylation efficiency(CCE)and light use (efficiency) (LUE) of C. fargesii were significantly higher than those of C.
