| contents | Seed germination of plant species from semiarid zones after hydration–dehydration treatments Mariana del Rocío Contreras Quiroz Marisela Pando Moreno Enrique Jurado Agrociencias Adaptation germination rate arid environments pregermination treatments Several authors have studied the influence of hydration-dehydration (HD) treatments on the germination of various plant species. Certain seeds preserve a “hydration memory” in order to retain, during dehydration, the physiological changes produced during hydration. The hypothesis is that the seeds of desert species will have a higher germination percentage and a lower mean germination time after being subjected to hydration-dehydration treatments. The aim of this study was to evaluate five species of plants, namely Frankenia gypsophila (I.M. Johnst.), Muhlenbergia arenicola (Buckl.), Muhlenbergia villiflora (Hitch.), Senna demissa (Rose) and Aristida adscencionis L., after being subjected to the following HD treatments: T1= 8h·day-1, T2= 8h·day-1 + 8h·day-1 + 8h·day-1, T3= 24h·day-1 and T4= control. HD treatments applied to the five species did not result in an increase in germination percentage. The hydration-dehydration cycles increased the germination rate and decreased the mean germination time (t50) of seeds of F. gypsophila, S. demissa and M. arenicola, which could be interpreted as one of the adaptations of these seeds to rain and drought intervals that occur in arid and semi-arid areas. 2015 artículo científico 2007-526X https://www.redalyc.org/articulo.oa?id=455544907005 en http://www.redalyc.org/revista.oa?id=4555 Revista Chapingo Serie Zonas Áridas application/pdf Universidad Autónoma Chapingo Revista Chapingo Serie Zonas Áridas (México) Num.1 Vol.XIV |
