Temperature Stress and Membrane Lipid Modification

Effects of Temperature on Lipid Unsaturation

“…1986). The second reason is that the sensitivity of agricultural crops to frost damage is thought by many researchers to be related to the content of unsaturated lipids, higher levels of unsaturation favouring hardiness to low temperatures (Kimura et at., 1982;Horvath et at.. 1983: Christiansen, 1984St John, Christiansen and Terlizzi, 1984). However, this relationship is still controversial (Willemot.…”

Oxygen‐mediated cold‐acclimation in cucumber (Cucumis sativus) seedlings

“…Following acclimation and on completion of the chilling period, plants were transferred to room temperature (25 ± 1°C) and placed under day‐night light cycling using fluorescent white light with an intensity of 14 µmol m −2 s −1 . Turgor loss in chilling‐stressed cucumber seedlings (Christiansen 1984) was manifested by the collapse of the hypocotyl region followed by death of the tissue. Chilling tolerance was defined by freedom from injury and, moreover, continued growth of chilled seedlings.…”
