Lund, Sweden.Organized by The Land Institute and LUCSUS (Lund University Centre for Sustainability Studies)Why has it been difficult to define the ideotype for a perennial oil-seed plant?Authors: Damián Ravetta1, David Van Tassel2 Luciana González-Paleo1, and Alejandra Vilela11Museo Egidio Feruglio-CONICET, Trelew, Patagonia Argentina2The Land InstituteThe ideotypes for the wild perennial candidate and the following cultivated plant are difficult to define. There is no consensus on which traits are more important and should be used. In part, this lack of a clear definition is due to scarce knowledge and poor understanding of the consequences of different plant traits, at different scales. Also, their relevance for the plant?s resource acquisition and use-efficiency, yield performance and its variability, and overall system sustainability, need to be determined. The same trait may have a positive or negative effect depending on the intended service. Drawing from knowledge on Silphium, Physaria, and other perennial oil-seed crops, we discuss structural and functional characters and their relevance to define future ideotypes for Silphium integrifolium.
