Survival and growth of seedlings of an endemic coastal dune shrub under drought conditions

| description | The rain pattern in coastal sand dunes along the Gulf of Mexico is clearly seasonal, and the dry season can last from 3 to 4 months. Plants that grow in this environment are exposed to low water availability during this time of the year. This paper describes the survival and growth of seedlings of Chamaecrista chamaecristoides, an endemic legume from the coastal sand dunes along the Gulf of Mexico. In order to study this species’ response in survival and growth under different conditions of water availability, four different watering regimes were applied: watering every other day (control); watering once a month; spray watering, and no water added. Seedlings were able to withstand total lack of watering for more than 80 days, after which they started wilting and dying. Survival was the same among control plants and those watered once a month. Relative growth rate and biomass allocation differed greatly among treatments. The drought tolerance observed, probably allows seedlings to survive during the dry months of the year. |

En las dunas costeras del Golfo de México, el patrón de precipitación es muy estacional, lo que da como resultado una marcada temporada de sequía que se prolonga de 3 a 4 meses, y a la que están expuestas las plantas que crecen en tal ambiente. Este trabajo describe los resultados obtenidos en un estudio sobre crecimiento y sobrevivencia ante diferentes condiciones de sequía de plántulas de Chamaecrista chamaecristoides, una leguminosa arbustiva, endémica de las dunas costeras del Golfo de México. Con tal objetivo se aplicaron cuatro tipos de tratamiento: riego cada 2 días (control); riego una vez al mes; riego por aspersión y sin riego. Las plántulas fueron capaces de tolerar hasta 80 días sin ningún tipo de irrigación. En las que recibieron agua una vez al mes, la sobrevivencia fue igual que en el lote control. Las tasas de crecimiento y la asignación de biomasa a las partes aérea y subterránea varían en función de la cantidad de agua aplicada. La gran tolerancia a la sequía probablemente permite a las plántulas de C. chamaecristoides sobrevivir durante la temporada de secas.
