摘要：Para analizar la respuesta del crecimiento de pasto Banderita a la salinidad se diseñó un experimento bifactorial de 11 tipos de sales a 8 concentraciones (0, 2, 4, 8, 12, 15, 19 y 28 dS m-1) y dos temperaturas (19 + 4 y 20 ºC), durante 15 días. Las sales que permitieron el mayor crecimiento fueron CaCl2.2H2O y clorhídrico-sulfática; el NaHCO3 y la salinidad sulfática registraron el menor crecimiento. Las sales geoquímicas permitieron el desarrollo vegetativo mayor en comparación con las sales puras. El crecimiento disminuyó al incrementarse la conductividad eléctrica de la sal. El desarrollo de la radícula fue menor al de la parte aérea tanto a temperatura ambiente como a temperatura controlada.
其他摘要：The effect of salinity and temperature on seedling growth was studied for Sideoats grama. A bifactorial experiment was designed: eleven salinity (eight levels 0, 2, 4, 8, 12, 15, 19 and 28 dS m-1) and two temperatures (19 +,- 4 and 20 ºC) during fifteen days. The growth showed a linear relationship with the electrical conductivity salt due to the fact that these were affected when increasing saline concentration; The salt with higher vegetative growth levels was the CaCl2.2H2O and clorhidric-sulfatic salinity; on the other hand, lower germination percentage was observed with NaHCO3 and sulfatic salinity. The vegetative growth of the root was highly affected by salts in comparison to the aerieal part, and both plant parts developed better using geochemical salts.
