Comparative phenological analysis of high yielding accessions of a Jatropha curcas (jatropha) germplasm bank, in Costa Rica

The species Jatropha curcas (jatropha) is characteristic of the Mesoamerican region, with its center of origin found in Mexico. It has been adapted for use in hedgerows and is also exploited for medicinal applications, based on traditional knowledge. It is currently classified as a valuable species...

It has been adapted for use in hedgerows and is also exploited for medicinal applications, based on traditional knowledge. It is currently classified as a valuable species for the production of oils for use as biofuels or paint diluents. In Costa Rica, a germplasm bank has been created in the Universidad de Costa Rica’s Fabio Baudrit Research Station, located in La Garita, Alajuela, which contains a total of 52 accessions from Costa Rica as well as some from other parts of the world. In the annual assessment of this germplasm bank, it was determined that the most productive accessions were Turrubares JCCR36, Jacó JCCR-3, El Barro de Turrubares JCCR-43, Orotina JCCR-1, Marichal JCCR-42, Tempate 1 JCCR-6, San Vito 2 JCCR-30, México 2 JCCR-31, India JCCR-27, and Tempate 1-Guanacaste JCCR-23. Three individuals were selected from each of these accessions for weekly evaluation, in which the number of female and male flowers, the number of inflorescences, and the number of fruits were estimated. A Kruskal Wallis non-parametric analysis was carried out with the data, and the results were correlated with levels of solar radiation and rainfall. The results of this analysis showed that the accessions with the highest yields were San Vito 2 JCCR-30, México 2 JCCR-31, and Tempate 1-Guanacaste-23. The highest solar radiation rates were recorded in the months of February and March of 2014, and between May and April of 2015. Negative correlations of more than 0.40 were found between solar radiation and flower production for the years 2014 and 2015, while production of inflorescences was positively correlated with rainfall and solar radiation. La especie Jatropha curcas (tempate) es típica de la zona mesoamericana, su centro de origen se ha establecido en México. Ha sido domesticada para uso en cercas vivas y por su valor medicinal según el conocimiento tradicional. En la actualidad se cataloga como una especie de alto valor para la producción de aceites que pueden tener uso en biocombustibles o como diluyente de pinturas. En Costa Rica se ha establecido un banco de germoplasma en la estación experimental Fabio Baudrit de la Universidad de Costa Rica, ubicada en la Garita de Alajuela. Comprende un total de 52 accesiones procedentes de todo el país y algunas de ellas de origen internacional. Producto del seguimiento anual del mismo se tuvo conocimiento de que las procedencias Turrubares JCCR36 ,Jacó JCCR-3 ,El Barro de Turrubares JCCR-43,Orotina JCCR-1, Marichal JCCR-42, Tempate 1 JCCR-6, San Vito 2 JCCR-30, México 2 JCCR-31,India JCCR-27, Tempate 1-Guanacaste JCCR-23, fueron las más productivas y de cada una se seleccionaron 3 individuos a los que se les dio un seguimiento semanal estimando el número de flores femeninas, masculinas, número de inflorescencias, número de frutos. A los datos se les aplicó un análisis no paramétrico de Kruskal Wallis y los resultados se correlacionaron con el nivel de irradiación y precipitación. Lo que permitió estimar que las procedencias más productivas fueron San Vito 2 JCCR-30, México 2 JCCR-31 y Tempate 1-Guanacaste-23. La mayor tasa de irradiancia se registró en los meses de febrero- marzo en el 2014 y marzo-abril en el 2015, se encontró correlaciones inversas mayores a 0,40 entre la radiación solar para los años 2014 y 2015, con respecto a la producción de flores, mientras que el comportamiento de la producción de inflorescencias presentó correlaciones con la precipitación y la radiación solar. 2018-10-11 2020-09-25T23:12:04Z 2020-09-25T23:12:04Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/3906 10.18845/tm.v31i3.3906 https://hdl.handle.net/2238/11817 eng https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/3906/pdf application/pdf Editorial Tecnológica de Costa Rica (entidad editora) Tecnología en marcha Journal; Vol. 31, Núm. 3: Julio-Setiembre 2018; pág. 110-121 Revista Tecnología en Marcha; Vol. 31, Núm. 3: Julio-Setiembre 2018; pág. 110-121 2215-3241 0379-3982
