abstract in recent years some research results have appeared that exogenous salicylic acid provided significant mitigation effect against salinity induced injuries in plants. an experiment was conducted to investigate the effects of salt stress and salicylic acid on radish (raphanus sativus l.) plants. after appearing first leaves, plants were treated by salicylic acid (0.2 mm) for 3 days and n...

When etiolated radish (Raphanus sativus var. hortensis f. gigantissimus Makino) hypocotyls were subjected to a continuous unilateral illumination with white fluorescent light (0.1 watt per square meter), the growth rate at the lighted side was strongly inhibited for the first 2 hours, while that at the shaded side showed no change. After 2.5 hours growth on the lighted side recovered gradually,...

A biological invasion of non-native plants is spreading into our natural areas and rights-of way. In the present work, Melia azedarach (Meliaceae) known for its high allelopathic potential is used to investigate its biopesticide capacity on the common model used in bioassays: Raphanus sativus (R. sativus). Exposure of R. sativus to M. azedarach (aqueous/ethanolic) leaves extracts result on toxi...

KAYMAK, H. C., I. GUVENC and A. GUROL, 2010. Elemental analysis of different radish (Raphanus sativus L.) Cultivars by using wavelength-dispersive X-ray fluorescence spectrometry (WDXRF). Bulg. J. Agric. Sci., 16: 769-774 The aim of this work is to study the applicability of a quantitative WDXRF (Wavelength-Dispersive X-ray Fluorescence) method, for determination of minerals in radish specimens...

Crop-wild hybridization may produce offspring with lower fitness than their wild parents due to deleterious crop traits and outbreeding depression. Over time, however, selection for improved fitness could lead to greater invasiveness of hybrid taxa. To examine evolutionary change in crop-wild hybrids, we established four wild (Raphanus raphanistrum) and four hybrid radish populations (R. raphan...

Hydroxycinnamoyltransferases which catalyze the formation of O-sinapoylcholine (sinapine) using l-0-sinapoyl-ß-D-glucose as acyl donor have been isolated from seeds of radish (Raphanus sativus L. var. sativus) and mustard (Sinapis alba L.) and purified 420and 293-fold, respectively. The enzymes (“sinapine synthase”) had apparent molecular weights of about 60,000 daltons and showed highest activ...

Plant materials have been found useful in decontamination of water polluted with phenolic compounds. The detoxification effect is due to peroxidases contained in plant tissue. Enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. A synthetic wastewater buffered at pH = 7.4 containing 0.9 mM phenol was treated in t...
