Cutinize

Sulphuric acid and chromic acid, even when concentrated, produce little effect on cutinized membranes, beyond removing traces of cellulose present in the cell-wall.

Leaves normally or experimentally developed as underground scales cutinize both upper and lower surfaces, and diminish the formation of collenchyma, palisade cells and intercellular spaces.

They may be separated early from the mother tissue by cutinizing their surface.
