متن کاملPre-haustorial resistance to broomrape (Orobanche cumana) in sunflower (Helianthus annuus): cytochemical studies.
Sunflower broomrape (Orobanche cumana Wallr.) is a root holoparasitic angiosperm considered as one of the major constraints for sunflower production in Mediterranean areas. Breeding for resistance is regarded as the most effective, feasible, and environmentally friendly solution to control this parasite. However, the existing sources of genetic resistance are defeated by the continuous emergenc...
متن کاملSunflower (helianthus Annuus L.) Response to Drought Stress at Germination and Seedling Growth Stages
Response of six sunflower hybrids/ breeding lines viz., G-101, SF-187, Hysun-33, Hysun-38, 64A-93 and S-278 to drought stress imposed at germination and seedling growth stages was investigated in a laboratory experiment (25±3C). Five water stress levels of zero (control), -0.35, -0.6, -1.33, and 1.62 MPa were developed using polyethyleneglycol-6000 (PEG-6000). Complete randomized design with th...
متن کاملSunflower Breeding for Resistance to Abiotic and Biotic Stresses
Due to a specific structure of its main organs (root, stem, leaves, and head), sunflower can be successfully grown on marginal soils and in semiarid conditions, and it is more resist‐ ant to abiotic stresses, than other field crops. Unfortunately, it is very sensitive to biotic stresses. In sunflower breeding for resistance to abiotic stresses, the greatest progress has been made in selection f...
متن کاملPLANT GROWTH REGULATORS INDUCED DROUGHT TOLERANCE IN SUNFLOWER (Helianthus annuus L.) HYBRIDS
Present study was conducted to investigate whether plant growth regulators viz. salicylic acid and ascorbic acid can alleviate the adverse effects of drought stress on germination and seedling growth of two sunflower hybrids (Hysun-33 and Hysun-38). Two (-0.06 MPa and -0.12 MPa) levels of drought stress were created by adding different concentrations of (PEG8000) polyethylene glycol in growth m...
