Figure 6From: Estimation of the solubility parameters of model plant surfaces and agrochemicals: a valuable tool for understanding plant surface interactionsSolubility parameter gradient model for the cuticle and cell wall covering the epidermis of plants. The three cuticular layers are indicated as: EWL (epicuticular wax layer), CP (cuticle proper) and CL (cuticular layer). From the EWL (−) to the cell wall (+) there is a gradual solubility parameter increase. The TEM micrograph corresponds to a transverse section of a juvenile, adaxial Eucalyptus globulus leaf surface (×80,000).Back to article page
