is the pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
 

 
The amount by which the diffusion pressure of a solution is lower than that of its pure solvent is known as
diffusuion pressure deficit or suction pressure.
 
                                                                  or

It is reduction in the diffusion pressure of water in solution or cell over its pure state due to presence of solutes in it and forces opposing diffusion.
DPD of a cell is influence by both osmotic pressure and wall pressure (turgor pressure) which opposes the endosmotic entry of water, i.e. DPD = OP - Wall pressure.
DPD is directly proportional to the concentration of the solution.
