It was studied that two species of tree grew under 3 treatments of soil water content,results showed that leaf water content of seabuckthorn is higher and water potential is lower than that of poplar in same soil water content.That results show seabuckthorn has tolerance drought higher than that of poplar.Photosynthesis rate of single leaf seabuckthorn can carry out higher rate in soil drought.Transpiration rate is different of photosynthesis rate.Single leaf water use efficiency of poplar is higher than th...
