Question

What is the formula of the FPD for withered (Shurken) plant cells? How is that situation possible?

Answer 1

Withered plant cells are those that have shrunk due to loss of water by evaporation without enough replacement. In this situation the cell membrane retracts and detaches from the cell wall. The cell wall moreover expands in length to stimulate the entrance of water making TP < 0. Since DPD = SF – TP and TP is negative (< 0) its formula becomes DPD = SF + |TP|.
