Reproductive ecology of Erigeron speciosus, a montane perennial herb: Evidence of self-incompatibility

Abstract

Realizamos un experimento para determinar la biología reproductiva de Erigeron speciosus (Asteraceae), una hierba montano perenne que se extiende por el Oeste de Norteamérica. Polinización de E. speciosus fue manipulado para entender: (1) >cuál es el sistema de apareamiento para E. speciosus (cruzamiento vs. autofecundación)? (2) >Es E. speciosus autoincompatible? (3) >La distancia del donador de polen afecta el éxito de la reproducción? (4) >El éxito de la reproducción será limitada por la recepción de polen (i.e., limitación polínica)? Comparamos la producción de semillas y la viabilidad de semillas por cinco tratamientos de polinización: polinización ambiente (control), exclusión de polinización (flores embolsadas), autopolinización solamente, y dos tratamientos de cruzamiento (donadores de polen cercanos y lejanos). Encontramos que E. speciosus es por gran parte autoincompatible y depende en cruzamiento para su reproducción. Aun así, la reproducción no fue limitada por polen en el sitio de nuestra investigación. También encontramos evidencia que la reproducción de E. speciosus es susceptible a depresión por exogamia.
