Abstract
Plants of Atriplex lentiformis had more saturated leaf lipids when grown at 43 C day/30 C night as compared to 23/18 C temperatures. In monogalactosyl diglyceride, the major change was the presence of hexadecatrienoic acid (16:3) at low but not high growth temperatures. In other lipids investigated, the major change was a decrease in linolenic acid (18:3) and increases in the more saturated fatty acids at high growth temperatures. Growth temperatures had little effect on the relative proportions of the galacto- and sulfolipids in the leaf. The increased lipid saturation is correlated with the greater thermostability of the photosynthetic apparatus at high growth temperatures in A. lentiformis but any cause and effect relationship is uncertain.This publication has 11 references indexed in Scilit:
