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.

Taxonomic notes and distribution of taxa of Orobanche gr. minor (Orobanchaceae) from Tunisia

2015

AbstractNew records for the flora of Tunisia and, in part, for North Africa of taxa of Orobanche sect. Orobanche subsect. Minores (Beck) Teryokhin, are reported. These records come from field research carried out between 2010 and 2014 in the Kroumiria region in northwestern Tunisia and herbarium studies. Infraspecific taxa and chorological data about the identified taxa (Orobanche amethystea Thuill., Orobanche canescens C. Presl, Orobanche hederae Duby, Orobanche litorea Guss., Orobanche minor Sm. and Orobanche pubescens d’Urv.) are reported. Literature data on host and distribution are also revised. Orobanche litorea is new to North Africa, and O. canescens has been confirmed for North Afr…

Modelling the effects of cropping systems on the dynamics of a parasitic weed, Phelipanche ramosa, in interaction with the non-parasitic weed flora

2010

International audience; The current decrease in herbicide use may increase and diversify weed flora in crops as well as companion bioagressors spreading via weeds. Among these bioagressors is Phelipanche ramosa, a parastic plant which is very harmful on oilseed rape. The objective of the present work was to develop a model (called PHERASYS) of the effects of cropping systems on parasite dynamics, in interaction with non-parasitic weed hosts. The structure of the first model version was based on models developed for other parasitic plants and on FLORSYS which quantifies the effects of cropping systems on non-parasitic weed flora. PHERASYS was parametrized with preliminary values from literat…

Types of names of Orobanche taxa described from North Africa

2013

In the framework of the revision of the genus Orobanche (including Phelipaea) in the Mediterranean area, the original material for 31 names of new taxa described from North Africa by Ball, Battandier, Forsska°l, Maire (partly with Emberger and Jahandiez), Persoon, Poiret and Pomel has been analysed. Typification is discussed, and where necessary types are designated. Accepted names and synonyms of the recognized taxa are given. Three species are illustrated, and one new combination (O. inexspectata) is proposed.

Orobanche apuana (Orobanchaceae) a new species endemic to Italy

2015

Orobanche apuana , a new species belonging to Orobanche sect. Orobanche , is described and illustrated from the Apuan Alps, Central Italy. Its relationships with the other species of the group of O. caryophyllacea ( O . grex Galeatae ) and with other Orobanche that parasitize Santolina species are examined. The names Boulardia latisquama , Orobanche lutea and O. teucrii are here lectotypified.

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…
