Morpho-physiological and adaptive variation of Italian germplasm of sulla (Hedysarum coronarium L.)
2014
Sulla is a biennial forage legume native to the central-western Mediterranean Basin and has increasing interest for regions with Mediterranean-climate. The Italian germplasm is a reservoir of variation for important agronomic traits. This study aimed to support breeding programs by investigating patterns of agronomic, adaptive and morpho-physiological variation among ecotypes collected from the three main Italian regions of species cultivation: central Italy, and the two islands of Sicily and Sardinia. Forage yield and morpho-physiological traits were evaluated at a site with Mediterranean climate in Sicily. Forage yield and cold tolerance in a cold-prone site of northern Italy were also as…
Adaptation of the tropical hybrid Euphorbia×lomi Rauh to the exposure to the Mediterranean temperature extremes
2014
Abstract Poysean ( Euphorbia × lomi Rauh) has been introduced in the Mediterranean countries as an ornamental plant for indoor uses. When used outdoor, few information is available about its ability to withstand the Mediterranean temperature extremes. An experiment in an open stand was performed to evaluate poysean tolerance to the winter and summer temperatures of the thermo Mediterranean climate and its ornamental value for urban greening. Two genotypes of poysean (Nguen Muang, NM; and Soi Budsanin, SB) with similar bracts and flower colours were grown at either 2 or 3 plants per pot during 23 months. Number of flower racemes and leaves per plant and plant height were recorded monthly. Ov…
Phenotyping: Case study of legumes plants
2012
International audience; The activities of the GEAPSI group, belonging to the large research unit Agroecology, is devoted to the genetic improvement of legumes important for European agriculture, and focuses on the cultivated species pea (Pisum sativum) and the field bean (Vicia faba). These studies are supported by basic research on a model legume, Medicago truncatula, used for taking advantage of the extensive genomics information available. Some examples will first illustrate how the combination of analytical, non-destructive phenotypical measurements and modelling can improve our understanding of plant functioning, taking as case studies legumes plants. The presentation will then describ…
