| description | An experiment was made to know the abiotic factors effect on the development of primary roots, growth and survival of red mangrove propagules (Rhizophora mangle L.). 180 propagules were collected at the Santa Clara swamp, in the North coast of Yucatan, Mexico, forming 6 groups of 30 individuals. Propagules were placed in orifices of a white exponded polyestirene sheet, maintaining them during 48 days in plastic containers, with a vertical position and with hipocotil immersed in water. There were considered three salinities: freshwater (5-7 ups), sea water (30-40 ups) and hypersaline water (70-75 ups), and two conditions of illumination (shade and direct solar radiation) with a maximum Albedo, representing a total of six treatments. Plants under shade conditions (SD, SM and SH) presented a survival of 100%, whereas the treatments exposed directly to solar radiation (LD, LM and LH) presented an inverse survival to the water salinity. Roots development was gradually less when increasing the salinity, intensifying when the propagules were exposed to direct radiation and a greater temperature of the water. The propagules at the shade-freshwater treatment (SD), presented a greater gain of weight due to the development of roots and leaves (only in this treatment leaves were developed). Salinity is the factor that controls the roots production in the R. mangle propagules at the establishment stage. Insolation and temperature cause an increase of physiological stress in the propagules, diminishing the production of roots and increasing mortality. |

Se realizó un experimento para conocer el efecto de los factores abióticos en el desarrollo de raíces primarias, crecimiento y supervivencia de propágulos de mangle rojo (Rhizophora mangle L.). Se colectaron 180 propágulos en la ciénaga de Santa Clara, en la costa norte de Yucatán, México, y se formaron 6 grupos de 30 individuos. Los propágulos se colocaron en orificios de una lámina de poliestireno expandido y se mantuvieron durante 48 días en recipientes de plástico, en posición vertical y con el hipocótilo inmerso en agua. Se establecieron tres salinidades: dulce (5-7 ups), marina (30-40 ups) e hipersalina (70-75 ups), bajo dos condiciones de iluminación (sombra y radiación solar directa) con un máximo albedo. Las plantas que permanecieron bajo condiciones de sombra (SD, SM y SH) presentaron una sobrevivencia de 100%, mientras que en los tratamientos expuestos directamente a la radiación solar directa (LD, LM y LH) presentaron una sobrevivencia inversa a la salinidad. El desarrollo de las raíces fue gradualmente menor al aumentar la salinidad, disminuyendo cuando los propágulos se encontraron expuestos a la insolación directa y a una mayor temperatura del agua. Los propágulos sometidos al tratamiento sombra-dulce (SD), presentaron una mayor ganancia de peso por el desarrollo de raíces y hojas (sólo en este tratamiento se produjeron hojas). La salinidad es el factor que controla la producción de raíces en los propágulos de R. mangle en la etapa de establecimiento. La insolación y la temperatura provocan un incremento del estrés fisiológico en los propágulos, disminuyendo la producción de raíces y aumentando la mortalidad.
