Abstract
Scalar perturbations in a perfect fluid with negative pressure are stu died. The expression of the density contrast delta is established when the equation of state has a barotropic form: i.e., p(0)=q epsilon(0). The behavior of delta is examined for different form of the backgroun d scale factor.
