Drought Tolerance in Cotton: Involvement of Non‐enzymatic ROS‐Scavenging Compounds
Compounds with reactive oxygen species (ROS)-scavenging ability were studied. High-performance liquid chromatography (HPLC) pattern of polyphenols, contents of proline and carotenoids, andExpand
Plant response to lead in the presence or absence EDTA in two sunflower genotypes (cultivated H. annuus cv. 1114 and interspecific line H. annuus × H. argophyllus)
EDTA cannot be used to enhance Pb absorption from nutrient solution by sunflower plants for phytoremediation purposes, and the ability of EDTA to prevent P b absorption by the plants could underly the mechanism of limiting of the negative impact of Pb ions. Expand
Reddening of cotton (Gossypium hirsutum L.) leaves : analysis of the polyphenol complex
The polyphenol complex of cotton leaves, expressing an abnormal red coloration under abiotic stress, was analysed by using high performance liquid chromatography (HPLC). Different polyphenol types -Expand
Antioxidant defense during desiccation of the resurrection plant Haberlea rhodopensis.
The role of some non-enzymic and enzymic antioxidants in desiccation tolerance of Haberlea rhodopensis was investigated and the polyphenol content increase and the main role of phenylethanoid glucosides in the protection of H. rhodopense was revealed. Expand
Heat shock responses of bean plants: involvement of free radicals, antioxidants and free radical/active oxygen scavenging systems
In non-acclimated bean plants heat shock induced oxidative damage (increase of free radical concentration and drop of bound thiols, indicating aggregation of proteins) which was regulated by theExpand
Sunflower plants (Helianthus annuus L.) cv. 1114 were used as test plants to investigate the combined toxicity effect of heavy metals present in soils collected from three different locations of aExpand
Reddening of Cotton (Gossypium Hirsutum L.) Leaves
Dramatic biochemical changes occurred in reddening leaves: strong accumulation of anthocyanins and drop of chlorophyll content, important increase of proline content and peroxidase activity, and lipid peroxide content indicative of membrane fragmentation was decreased. Expand
Investigation a single-spiral vortex in a swirl flow
The work is aimed at a detailed study of large-scale helical vortex structures emerging in a high turbulent intensively swirling flow. It was shown that the vortex formed in the chamber by installingExpand
Comparison of flavonoid profiles of cultivated plants of Achillea asplenifolia, Achillea collina and cultivar "Proa"
No significant difference was found in the flavonoid profiles of the extracts of the both origins of the cultivar “Proa” and A. collina, and intraspecific variability of flavonoids when the plants are grown in the uniform conditions was determined. Expand
Evaluation of the efficiency of using the swirl flow with the formation of helical vortices
The paper reports on the results of numerical simulation of large-scale stationary vortices forming in hydrodynamical model of a vortex combustor. In particular, the effect of boundary conditions onExpand
