Abstract

Plant biochemists and physiologists have recently been presented with a working model which may explain the mechanism for chilling sensitivity and resistance in higher plants. The model is based on the observation that membranes from chilling sensitive plants contain a significantly higher proportion of di-saturated molecular species of PG than do those from chilling resistant species (Murata, 1983). [For the purposes of this study “saturated” fatty acids are defined as 16: 0, 18: 0 and 16: 13t.] Exceptions to this general rule occur among the Solanaceae and the C4 grasses (Roughan, 1985).
