Study on Photosynthetic Diurnal Variation of Salix matsudana Under Salt Stress
The Salix matsudana were used as experimental material to study the effect of salt stree on the photosynthetic diurnal variation.The results showed that the photosynthetic rate of Salix matsudana showed a bimodal type in the standard contrast and mild stress conditions,while showed a single peak type in the moderate and severe stress condition with a trend first rise then falling.The stomatal conductance showed a bi-modal type in the standard contrast and mild stress conditions,while showed a single peak type in the moderate and severe stress conditions with a trend of gradual decline.The daily variation trends of transpiration rate was similar with the stomatal conductance.The intercellular CO2 concentration under stress treatment were higher than the standard contrast,and increased with the salt stress levels.
