Abstract

Exogenous application of choline reduced chill-sensitivity in seedlings of mung bean (Vigna radiata L. Wilcz.) cv. Berken. In contrast with choline treatment chill-hardening at 12°C, 4.2 g m-3 vapour saturation deficit for 4 days was ineffective in preventing symptoms of chilling injury when subsequently chilled at 5°C for 24 h under light conditions. The choline treatment reduced stomatal aperture prior to chilling and this reduced the development of a chilling-induced water stress in the primary leaves at 5°C. Choline treated plants showed almost complete recovery of leaf water content after chilling, while untreated plants showed a progressive desiccation of the leaf tissue throughout a chill-warm cycle. Choline caused increases in the concentration of chlorophylls, carotenoid and the carotenoid/chlorophyll ratio in non-chilled plants. During chilling photo-oxidative degradation of chlorophyll and carotenoid and the associated decreases in chlorophyll sola b and carotenoid/chlorophyll ratios were prevented by choline application.
