Nine species classified as rare in the Slovenian Red Data Book are also present and include Aconitum anthora, Cercis siliquastrum, Delphinium fissum, Euphrasia italica, Juniperus oxycedrus, Laburnum alschingeri; Orobanche hederae is found only in the Great Valley.

Skocjan Caves Regional Park, Slovenia 2008

Localized species of note include red broomrape Orobanche alba, sea spleenwort Asplenium marinum and oyster plant Mertemsia maritima.

In this respect, many investigations have reported that flax, a non-host, is regarded as a crop well suited for the control of Orobanche parasitism under field conditions because it is capable of including the seeds of Orobanche spp. to germinate, without itself being parasitized.

Ultimately, such response might support the view that although the flax plants showed a substantial influence in stimulating different parasitic seeds (Orobanche spp. and Striga spp.) in vitro, the flax plants have limited influence in reducing these parasitic weeds under field conditions, since the flax plants secrete the active material in a very limited period

The objective of the present work was to study the efficiency of flax as a trap crop in reducing Orobanche infestation on Vicia faba and the growth stages at which the stimulating germination factor was found in flax.

Flax roots free of infection by the three Orobanche spp.

Orobanche parasitism on faba bean and other hosts must be considered impractical to a large extent under field conditions, since the flax plant exudate the active material only during the germination period.

Three Orobanche species, O. crenata, O. ramosa and O. aegytiaca, failed to infect flax roots (Linum usitatissimum) at 30, 45 and 60 days from sowing, but heavy infection was observed with O. crenata on faba bean roots
