Characterization of strigolactones produced by Orobanche foetida and Orobanche crenata resistant faba bean (Vicia faba L.) genotypes and effects of phosphorous, nitrogen, and potassium deficiencies on strigolactone production

Effects of Salicylic Acid and Indole Acetic Acid Exogenous Applications on Induction of Faba Bean Resistance against Orobanche crenata

“…Parasitic plant O. crenata is considered among the most devastating constraint for faba bean production in many countries in the Mediterranean regions ( Amri et al, 2019 ; Briache et al, 2019 ; Ennami et al, 2017 ; Rubiales, 2018 ). During the last decades, research activities on Orobanche control were intensified with focus on the physical and biochemical host-parasite interface including the parasite seed germination stimulant and inhibitors, host plant roots physical barrier and root architecture ( Abbes et al, 2009 ; Fernández-Aparicio et al, 2014; Pérez-de-Luque et al, 2010 ; Trabelsi et al, 2017 ). Among all the tested control methods, only genetic resistance and chemical control resulted in a successful control of the parasite with a significant decrease of Orobanche infestation level ( Rubiales and Fernández-Aparicio, 2012 ).…”

Recent research progress in combatting root parasitic weeds

“…Until recently, resistance mechanisms identified in the faba bean against O. crenata were ascribed to inhibition of radicle penetration and tubercle development [68]. However, a resistance mechanism in terms of low induction of germination has been found in faba bean cultivars, including Giza402 against O. crenata, O. foetida and P. aegyptiaca [68][69][70][71][72][73]. Resistance of several faba bean varieties against more than two Orobanche/Phelipanche spp.…”

“…crenata [158] and faba bean-O. foetida [73]. Only P deficiency promoted SL exudation in alfalfa and tomato, and N as well as P deficiencies promoted it in Chinese milk vetch (Astragalus sinicus), marigold (Tagetes patula), lettuce (Lactuca sativa) and wheat [159].…”

Chlorophyll content and fluorescence as physiological parameters for monitoring Orobanche foetida Poir. infection in faba bean

“…The devastating effect of Orobanche is associated with their multiplication rate and high seed viability (15–20 years) [ 8 ]. Many control methods were used to control Orobanche , including agricultural practices, chemical and biological methods [ 9 , 11 , 14 ]. The chemical method using especially synthetic strigolactones and herbicides were the most explored but resulted in a limited success due to their application complexity in the farmer’s field [ 8 ].…”
