La induccion de resistencia por sequia a 25 grados centigrados y 40 por ciento de HR al no proporcionar agua a las raices durante 4 dias es tan efectiva en la prevencion del dano por heladas en las hojas de Phaseolus vulgaris, como la induccion de resistencia mediante enfriamiento durante 4 dias a 12 grados centigrados y 85 por ciento de HR. Durante la induccion de resistencia por enfriamiento, el grado de insaturacion de los acidos grasos asociados con fosfolipidos aumento y se penso que esto prevenia la perdida de agua y la de electrolitos al disminuir la temperatura a la cual se presentan cambios de fase en la membrana de lipidos a menos de 5 grados centigrados (Wilson y Crawford, 1974). No obstante, la induccion de resistencia por sequia a 25 grados centigrados y 40 por ciento de HR. no condujo a un aumento en el grado de insaturacion de los fosfolipidos o los glicolipidos, lo cual indica que los cambios de la fase lipida no son la causa primera del dano por las heladas. Mas aun, una reconsideracion de las condiciones bajo las cuales las hojas de P. vulgaris pierden agua y electrolitos, sugiere que los cambios de fase en la membrana de los lipidos del plasmalema y otros organulos a 5 grados centigrados son tan solo de importancia secundaria en la determinacion de la intensidad y la rapidez del dano por las heladas. La causa fundamental del dano por las heladas al pasar hojas de frijol de 25 grados centigrados y 85 por ciento de HR a 5 grados centigrados y 85 por ciento de HR, es la deshidratacion de las hojas debido a la apertura de los estomas en el momento en que la permeabilidad de las raices al agua es baja. El factor esencial que induce la resistencia al dano por las heladas en P. vulgaris es la falta de agua y no la temperatura baja per se. (RA-CIAT) |

| Summary, etc |
Drought hardening at 25 degrees C, 40 percent RH by witholding water from the roots for 4 days is as effective in preventing chilling injury to the leaves of Phaseolus vulgaris as 4 days chill hardening at 12 degrees C, 85 percent RH. During chill hardening the degree of unsaturation of the fatty acids associated with the phospholipids increased, and this was considered to prevent water loss and electrolyte leakage by lowering the temperature at which phase changes occur in the membrane lipids to below 5 degrees C (Wilson and Crawford, 1974). However, drought hardening at 25 degrees C, 40 percent RH resulted in no increase in the degree of unsaturation of the phospholipids or glycolipids, suggesting that lipid phase changes are not the primary cause of chilling injury. Furthermore, a reexamination of the conditions under which water and electrolytes leak from the leaves of P. vulgaris indicates that phase changes in the membrane lipids of the plasmalemma and other organelles at 5 degrees C are only of minor importance in determining the extent and speed of chilling injury. The primary cause of chilling injury to P. vulgaris leaves on transfer from 25 degrees C, 85 percent RH to 5 degrees C, 85 percent RH is leaf dehydration due to the opening of the stomata at a time when the permeability of the roots to water is low. The primary factor inducing hardening against chilling injury in P. vulgaris is water stress and not low temperature per se. (AS) |
