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. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.52 2016 FORESTRY 50 / 64 = 0.781 2016 Q4 T3 0.235 2016 Forestry 2016 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martín-Gil, Jesús Ramos-Sánchez, María del Carmen Hernández-Navarro, Salvador Martín-Gil, Francisco Javier 5011 500 Universidad de Zaragoza Dpto.
