Some growth and biochemical changes of viola (Viola × wittrockiana) and Snapdragon (Antirrhinum majus) ornamental plants to freezing stress
Exposure to freezing stress causes physiological, biochemical and molecular changes in plants, that are associated with reduced growth and development. In these areas, sensitive species are removed and the geographical distribution is changed. This study was conducted to evaluate some vegetative and biochemical responses of two cold-resistant ornamental plants, viola (Viola wittrockiana) and Sn...
متن کاملCharacterization of Phytochemicals in Petals of Different Colours From Viola × wittrockiana Gams. and Their Correlation With Antioxidant Activity
A study to establish relationship between the petal colour, extraction solvent, phenolic, flavonoid, anthocyanin content and antioxidant activity in three varieties of Viola × wittrockiana (yellow, red and violet) is reported in this article. Identification and quantification of flavonoids and anthocyanins using HPLC-DAD-ESI-MS is also presented. The antioxidant activity was studied by four dif...
متن کاملEffect of Light Combination and Timing of Supplemental Lighting on Growth Characteristics and Flowering of Pansy (Viola × wittrockiana Rose)
The goal of this study was to examine how different light combinations and timing of supplemental lighting affect the vegetative and reproductive responses of pansy (Viola × wittrockiana Rose). The present study was designed as a factorial experiment based on a completely randomized block design with three replications and two factors of timing of supplemental lighting (night-interrupt...
متن کاملNatural infection of Viola cornuta (Violaceae) with Cucumber mosaic virus, subgroup I.
Plants of Viola cornuta displaying typical virus symptoms were observed during spring 2003 in a plant nursery in Córdoba, central Argentina. Electron microscopic examinations of symptomatic leaf samples revealed the presence of isometric virus-like particles about 30 nm in diameter. Subsequent serological analysis allowed the identification of the pathogen as a subgroup I strain of Cucumber mos...
متن کاملPhenolic compounds and antioxidant activities of Liriope muscari.
Five phenolic compounds, namely N-trans-coumaroyltyramine (1), N-trans-feruloyltyramine (2), N-trans-feruloyloctopamine (3), 5,7-dihydroxy-8-methoxyflavone (4) and (3S)3,5,4'-trihydroxy-7-methoxy-6-methylhomoisoflavanone (5), were isolated from the fibrous roots of Liriope muscari (Liliaceae). Compounds 2-5 were isolated for the first time from the Liriope genus. Their in vitro antioxidant acti...
