Physiological and gene expression responses of sunflower (Helianthus annuus L.) plants differ according to irrigation placement.
To investigate effects of soil moisture heterogeneity on plant physiology and gene expression in roots and leaves, three treatments were implemented in sunflower plants growing with roots split between two compartments: a control (C) treatment supplying 100% of plant evapotranspiration, and two treatments receiving 50% of plant evapotranspiration, either evenly distributed to both compartments ...
متن کاملTOLERANCE OF SUNFLOWER (Helianthus annuus L.) TO IMAZETHAPYR
The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid "Zoltan" (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were recorded. ALS (acetolactate synthase) enzyme activ...
متن کاملEffects of antimony on redox activities and antioxidant defence systems in sunflower (Helianthus annuus L.) plants
The alterations induced by the toxicity of antimony (Sb) in the roots and leaves of sunflower plants were determined. The plants were grown hydroponically with different concentrations of Sb, a heavy metal which reduces biomass production and growth. There was preferential accumulation of Sb in the tissues of the roots, with the concentrations in the leaves being much lower. The accumulation of...
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 کاملResponse of Sunflower (Helianthus annuus L.) Leaf Surface Defenses to Exogenous Methyl Jasmonate
Helianthus annuus, the common sunflower, produces a complex array of secondary compounds that are secreted into glandular trichomes, specialized structures found on leaf surfaces and anther appendages of flowers. The primary components of these trichome secretions are sesquiterpene lactones (STL), a diverse class of compounds produced abundantly by the plant family Compositae and believed to co...
