Ortega (1985) proposed a simple first-order differential equation to describe plant cell extension and, unlike the Lockhart equation (Lockhart, 1965), it takes into account elastic deformation of the cell wall. Cosgrove (1985) and Ortega (1985) solved the equation for the particular case of a previously growing plant cell that is deprived of its water source; thus, GR 5 0. The results (confirmed by experiments) show that P(t) decreases exponentially to the turgor threshold Y due to the cell… CONTINUE READING
