Typification of the name orobanche ebuli huter & rigo (orobanchaceae) and its taxonomic implications
2018
The present contribution is part of the ongoing work aimed at researching and identifying the original material on which the names of Orobanche Linnaeus (1753: 632) described for Europe and the Mediterranean are based (Domina et al. 2005, Domina & Stepanek 2009, Domina et al. 2013, Carlón et al. 2015). It falls within the researches promoted by the Italian Botanical Society aimed at recognizing and typifying all the taxa described from Italy and their loci classici, in order to increase their systematic knowledge and promote further studies (Domina et al. 2012, Peruzzi et al. 2015, Brundu et al. 2017). Orobanche ebuli Huter & Rigo (1907: 354), is an Italian endemic (Peruzzi et al. 2…
Les semences de la plante parasite orobanche rameuse ont une dormance saisonnière qui varie au niveau intraspécifique et une faible mortalité au champ
2019
L’orobanche rameuse (Phelipanche ramosa) est une plante parasite bioagresseur majeur du colza en France. Les connaissances sur la viabilité et la dormance de ses semences dans le sol sont cruciales pour contrôler l’orobanche mais restent à acquérir. La présente étude vise à quantifier ces processus grâce à une expérience d’enfouissement de semences au champ de deux ans. Deux populations génétiquement distinctes ont été étudiées, collectées sur colza d’hiver et chanvre respectivement. La mortalité des semences est très faible pour les deux populations (4-7% par an). Les semences montrent une dormance saisonnière dont le timing et l’amplitude varient en fonction de la population, avec une dor…
Broomrape weeds. Underground mechanisms of parasitism and associated strategies for their control: a review
2016
prod 2018-285d SPE GESTAD Agrosup INRA CT?; International audience; Broomrapes are plant-parasitic weeds which constitute one of the most difficult-to-control of all biotic constraints that affect crops in Mediterranean, central and eastern Europe, and Asia. Due to their physical and metabolic overlap with the crop, their underground parasitism, their achlorophyllous nature, and hardly destructible seed bank, broomrape weeds are usually not controlled by management strategies designed for non-parasitic weeds. Instead, broomrape are in a current state of intensification and spread due to lack of broomrape-specific control programs, unconscious introduction to new areas and may be decline of …
The status of Orobanche crenata in Sicily and preliminary observations on Orobanche crenata susceptibility in Vicia faba
2013
Since more than 10 years we are recording Orobanche crenata populations variations and testing traditional remedies to assess their applicability in a low impact agriculture that may be applied also in developing countries. Starting from the observation that often in C Sicily dense fields of Broadbean show lower Broomrape infestation, we did some preliminary observations on Orobanche crenata susceptibility in Vicia faba var. faba and Vicia faba var. equina with different agricultural techniques. First results show a higher resistance of the latter sowed at higher densities.
