Light and micorrhizal effect in seed germination of tropical dry forest tree species
Germination is a fundamental process in natural regeneration of tropical forest. In dry forest, germination is affected by the pronounced seasonality, which causes a high heterogeneity in understory light availability, as well as the biological interactions with soil microorganism, i.e. micorrhizae....

| description | Germination is a fundamental process in natural regeneration of tropical forest. In dry forest, germination is affected by the pronounced seasonality, which causes a high heterogeneity in understory light availability, as well as the biological interactions with soil microorganism, i.e. micorrhizae. The germination of three tree species of dry Tecoma stans (L.) Juss. ex Kunth, Senna racemosa (Mill.) H.S. Irwin y Barneby, y Bauhinia forficata Link. subsp. pruinosa (Vogel) Fortunato & Wunderlin was studied. Under a factorial design with three soil treatments: control (forest soil + nutriments), micorrhizae (Glomus intrarradices) and chemical control (Triple 17: Nitrogen + Phophorous + Potassium); and four light treatments (10%, 30%, 50% and 70%), the germination process was evaluated taken nine response variables. Both factors affected germination responses in an independent form. Interactive effects were only found in mean germination rate of T. stans, and uncertainty of the germination synchrony of B. forficata. Low and intermediate light levels availability increased the mean germination rate and germination value of T. stans. In addition, percentages of germination of S. racemosa were higher in intermediate and high light levels. In B. forficata we found no effects produced by light availability on germination process. The addition of micorrhizae produced positive effects on mean germination rate of T. stans, and highest percentages of germination in S. racemosa and B. forficata, although assynchronically. Adequate light availability and addition of micorrhizae to the substrate would cause benefits to germination in situ of important tree species used in restoration tropical dry forest programs, although with certain restriction. |

La germinación es un proceso fundamental en la regeneración natural de las selvas tropicales. En las selvas secas la germinación es afectada por la pronunciada estacionalidad que causa una alta heterogeneidad de la cantidad de luz que llega al suelo y la interacción con las micorrizas. La germinación se estudió en tres especies características de selvas secas: Tecoma stans (L.) Juss. ex Kunth, Senna racemosa(Mill.) H.S. Irwin y Barneby, y Bauhinia forficata Link. subsp. pruinosa (Vogel) Fortunato & Wunderlin. El proceso germinativo fue evaluado en un diseño factorial con tres tratamientos de germinación: testigo (suelo de la selva de origen + nutrimentos), micorriza (Glomus intrarradices) y testigo químico (Triple 17: Nitrógeno + Fósforo + Potasio); y cuatro niveles de luz (10%, 30%, 50% y 70%); se evaluó el proceso germinativo con nueve variables. Ambos factores influyeron de manera independiente en la respuesta de germinación y solo se encontraron efectos de interacción en la tasa promedio de germinación de T. stans y en la incertidumbre de la sincronía de la germinación de B. forficata. Los niveles bajos e intermedios de luz aumentaron la tasa promedio de germinación y valor máximo de germinación de T. stans. Además, los porcentajes de germinación de S. racemosa incrementaron en niveles intermedios y altos de luz. En B. forficata no se registró ningún efecto de la disponibilidad de luz sobre el proceso de germinación. La adición de micorriza afectó positivamente la tasa promedio de germinación en T. stans y los porcentajes de germinación en S. racemosa y B. forficata, aunque en estas dos últimas de forma asincrónica. El uso de niveles de luz adecuados y la adición de micorriza beneficiarían la germinación in situ de especies importantes en la regeneración de las selvas secas tropicales, aunque con ciertas restricciones.
