Galactolipase Activity and Free Fatty Acids in Chloroplasts as Indicators of Chilling Sensitivity of Closely Related Plant Species

Part of the NATO ASI Series book series (NSSA, volume 168)


Cold and dark treatment of leaves of chilling-sensitive(CS) plants results in both accumulation of free fatty acids (FFA) (cf.1) and degradation of galactolipids2 in chloroplasts. Moreover both galactolipase activity and FFA levels appear to be higher in CS than chilling-resistant plants3,4. In this communication data concerning these two parameters in chloroplasts of closely related plants species but of different chilling sensitivity are presented.
