 In: Physiologia Plantarum (Denmark). (Mar 1981). v. 51(3) p. 287-290Summary: Stomatal behaviour and the amount and synthesis of epicuticular waxes were studied in maize leaves of various degrees of chilling resistance in order to investigate the rapid desiccation characteristic of chilling injury. In contrast to the resistant variety (KSC 360), the sensitive line (Lyc) failed to close the stomata during chilling treatment. Both, the amount of epicuticular waxes and their degree of labeling by 1-('14)C-acetate were much higher in the resistant than in the sensitive leaves. Chilling-sensitivity was also related to a suppressed conversion of free fatty acids into free primary alcohols
