Genetic self-compatibility in a south american species of ourisia (scrophulariaceae)

Abstract

Controlled hand self- and cross-pollination and emasculations were performed on Ourisia poeppigii Benth. (Scrophulariaceae) from the Chilean Patagonia. Ourisia poeppigii is highly self-compatible and strongly autogamous. No evidence of obligate agamospermy was seen. This first breeding system record for a South American species of the genus Ourisia accords with a report of self-compatibility provided by Schlessman (1986) for Ourisia macrocarpa Hook. f. ssp. calycina (Col.) Arroyo from New Zealand. However, O. poeppigii is potentially more strongly autogamous than the New Zealand species. © 1990 Taylor & Francis Group, LLC.
