Abstract:
Setting two water levels,appropriate water and severe water stress，pressure-volume curve on two root apple stocks hydraulic architecture of Malus hupehensis and Malus prunifolia were tested，and the effects of water deficit on pressure-volume curve water parameters of Malus hupehensis and Malus prunifolia were studied.The results showed that water deficit affect gas exchange of the ground part.On the condition of severe drought，compared values of ψstlp ，ψssat， RWCtlp， ROWCtlp，ε′of Malus prunifolia with Malus hupehensis，Malus prunifolia on a low level.It showed that Malus prunifolia had better abilities resistance to water stress and keeping water of seeding，more elastic cell wall.Used by the subordinate function comprehensive estimating analysis pressure-volume curve water parameters,△values of Malus prunifolia was larger than Malus hupehensis.Pressure-volume curve water parameters in plants could adjust accordingly with environment.On the condition of suitable soil moisture and severe drought，Malus prunifolia reflects the water strategy which optimal Malus hupehensis.After studied with pressure-volume curve water parameters，it showed that the abilities of maintaining turgor of Malus prunifolia was better than Malus hupehensis and the drought resistance which optimal Malus hupehensis.
