Cuticle was isolated by infiltrating leaf disks with a 2 - 3% (w/v) solution of Pectinase (Nutritional Biochemicals Corp) or Enzyme 19 (Rohm and Haas Co.) buffered to pH 3.5 - 4.5 and containing 100 ppm. Merthiolate (Thimerosal, Lilly). Gentle rotary agitation at 35[degree]C resulted in a suspension of isolated cells, vascular strands, and cuticle disks. Responses of various spp. and some properties of the cuticle disks are descr.
