This study was conducted in 2020 to investigate the influence of melatonin (10, 50 and 100 µM) given three methods (immersion, irrigation, foliar spraying) on some physiological aspects tomato seedlings inoculated with root-knot nematode Meloidogyne incognita [(Kofoid White) Chitwood]. The were 1000 second-stage juveniles M. incognita. Dualex® optic sensor used situ measure total chlorophylls, ...

Flavonols are compounds with radical-scavenging activities that can prevent the harmful effects of free radicals. Their activity has attracted significant attention. Recently, quantum chemistry-based methodologies have significantly improved understanding due to dramatic increases in computational power and software improvements. A standardized analysis method for estimating radical scavenging ...

Plants in high-altitude habitats are exposed to severe environmental stressors, including extreme temperatures and irradiation, which can have wide-ranging effects on changes of secondary-metabolite profiles higher plants. Altitude-related variation levels polyphenols organs medicinal food plant species has not yet been investigated sufficiently. This study was focused quantitative classes indi...

Abstract Flavonoids, such as anthocyanins, proanthocyanidins, and flavonols, are widespread plant secondary metabolites important for adaptation to diverse abiotic biotic stresses. Flavonoids can be variously hydroxylated decorated; their biological activity is partly dependent on the degree of hydroxylation B-ring. Flavonoid biosynthesis regulated by MYB transcription factors, which have been ...
