Interaction between Broomrapes
and their HostsJournal of Phytology, 3(1): 68-72.
Broomrape seed transport has been suggested as one of the main factors in the dispersion of the infestation .
Individual broomrape plants produce an impressive number of seeds from 50,000 to 500,000  that maintain their viability in the soil for up to 20 years .
Baraca has a high level of resistance to broomrape (Orobanche crenata Forssk.), thus allowing sowing in highly broomrape infected fields in many areas of southern Spain.
Baraca originated from a cross between broomrape resistant breeding line VF1071 and 'Alameda'.
Chickpea (Cicer arietinum) is a host of crenate broomrape
(Orobanche crenata) that suffers little damage in the traditional spring sowing, but there is concern that the continued spread of the practice of winter sowings might lead to an outbreak of broomrape
infection in chickpea.
, a holoparasitic angiosperm that infects sunflower roots, is currently regarded as being one of the most important constraints for sunflower production in Spain and the regions around the Black Sea (Alonso et al., 1996; Bulbul et al., 1991; Dominguez et al., 1996a; Shindrova, 1994).
is a parasitic angiosperm infecting the roots of sunflower and causing severe crop losses in Spain and other countries of southern Europe, as well as in many of the countries of the former USSR, the Middle East and China (Parker, 1994).
are necessary, although seed reduction, weakness, and necrosis of broomrape
have been observed.
Application of Ammonium Sulphate @ 200 kg [ha.sup.-1] recorded significantly later emergence of broomrape
but it was at par with treatments [F.sub.3] (Castor cake; 200 kg [ha.sup.-1]) and [F.sub.4] (Neem cake; 200 kg [ha.sup.-1]) whereas, significantly the earliest broomrape
emergence was observed under the treatment [F.sub.1] (Control) (Table 1).
betae was observed on the underground parts of broomrape
shoots, on both haustoria and tubers, by digging plants from the soil (Fig.
