In this study the low temperature thermal behavior of calafate seeds was analyzed by Differential Scanning Calorimetry (DSC), and a vibrational characterization of their different components was conducted by infrared spectroscopy (FTIR). In cold-acclimated plants, such as calafate, the total percentage of polyunsaturated fatty acids in their seeds is significantly higher than that of saturated fatty acids. Successive freezing-thawing cycles lead to increased formation of linoleic (LA) and linolenic (LNA) a-crystals. This process would barely modify the phase-transition temperature of the lipid membrane but would lead to an increase in the membrane fluidity (LNA would make the cell membranes more fluid during seed development). It seems that processes in membranes rather than in the glassy cytoplasm may determine the cooling resistance. 000098188 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000098188 590__ $$a0.52$$b2016 000098188 591__ $$aFORESTRY$$b50 / 64 = 0.781$$c2016$$dQ4$$eT3 000098188 592__ $$a0.235$$b2016 000098188 593__ $$aForestry$$c2016$$dQ3 000098188 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000098188 700__ $$aMartín-Gil, Jesús 000098188 700__ $$aRamos-Sánchez, María del Carmen 000098188 700__ $$aHernández-Navarro, Salvador 000098188 700__ $$aMartín-Gil, Francisco Javier 000098188 7102_ $$15011$$2500$$aUniversidad de Zaragoza$$bDpto.
