“…Labrousse et al (2001) showed that the resistance of sunflower to O. cumana was related to the presence of an encapsulating layer between the parasite and the root tissue of the host. Similarly, an increase in production of phytoalexins (maackian and medicarpin) has been reported in resistant chickpea (Wegmann et al, 1991), which may play a role in early blocking of the broomrape infection.…”

“…The total orobanche number per plant was recorded and scored visually using a 1 to 5 scale (1: attachment of haustorium to host root; 2: small tubercles without root development; 3: tubercles with crown roots without shoot formation; 4: underground tubercles with shoot formation; 5: emergence of spikes) (Labrousse et al, 2001). In addition, orobanche tubercle dry weights (DW) per plant was determined after drying fresh samples at 80 °C for 48 h. (2) At crop maturity, orobanche incidence (percentage of host plants showing emerged spikes using a 0 to 100% scale, Abbes et al, 2007a;2007b), the number of emerged orobanche, total orobanche DW and grain yield were determined in the two central rows (4 m²).…”

“…The six chickpea genotypes were grown in 5 L pots containing sterilized soil and river sand (2:1) artificially inoculated with 20 mg (Labrousse et al, 2001). In addition, orobanche DW (80 °C for 48 h) per chickpea plant, pod number and shoot and root DW (g) of the different chickpea genotypes were recorded.…”

“…Estimated germination percent were performed weekly from 20 to 62 d after inoculation by O. foetida seeds (DAI). In addition, the total number of tubercles was counted every 3 d from 55 to 104 d after plant inoculation (DAI), and classified according to their developmental stage (Labrousse et al, 2001). Seven petri dishes were prepared for each genotype.…”

In Tunisia, broomrape (Orobanche foetida Poir.) causes major drawbacks especially in faba bean (Vicia faba L.) Chickpea (Cicer arietinum L.) suffers little damage compared to faba bean, but with the winter sowing chickpea cultivars, broomrape might become a serious problem for chickpea cultivation. The development of resistant cultivars remains the most efficient way to solve this problem. The behavior of six chickpea genotypes to O. foetida was studied under field natural infestation and artificial inoculation in pots and petri dishes in greenhouse conditions. During the cropping seasons 2010-2011 and 2012-2013 the level of infection was very low. The number of emerged parasites per host plant varied from 0.18 to 0.43 and the incidence from 6.5% to 23%. Among the six tested genotypes, G1, G2, and G4 showed partial resistance to O. foetida with low number and dry weight of emerged parasite and high grain yield compared to the other genotypes, although no significant differences were recorded. In pot experiments, the number and total dry weight of broomrape per plant were lower for G1 and G2 genotypes than the other genotypes. Parasitism does not affect significantly the shoot dry weight and number of pods of these genotypes. The total chlorophyll content was significantly reduced under infestation in all genotypes. In Petri dishes experiments, results showed that percent germination of O. foetida seeds varied from 49% to 65% and does not play a role in the resistance of chickpea genotypes. In contrast, broomrape attachment was lower and slower for the genotypes G1, G2, and G4 than the other genotypes. Resistance in chickpea genotypes was characterized by few parasite attachments on roots and a limited growth of established tubercles. No necrosis of attached tubercles was observed in the different experiments.

Drought tolerance of two sunflower (Helianthus annuus L.) genotypes, cultivated cultivar 1114 and interspecific line H. annuus × H. mollis, was studied under laboratory conditions using PEG-6000. Four levels of osmotic stress (-0.4, -0.6, -0.8 and -1.0 MPa) were created and performances were monitored against a control. Physiological and biochemical stress determining parameters such as malondialdechyde (MDA), proline content, and hydrogen peroxide (H 2 O 2 ) were compared between seedlings of both genotypes. The results indicated that both genotypes have similar responses at four osmotic potentials for all traits studied. All seedling growth parameters such as germination percentage, root length, shoot length, root and shoot dry weight decreased with increasing osmotic stress. MDA, proline, and H 2 O 2 were found to be increased at different osmotic gradients in comparison to control. Cultivar 1114 was less affected than the interspecific line under these stress conditions. The data observed in the experiments revealed that perennial wild H. mollis can hardly be considered to be an excellent candidate of drought tolerance genes.
