Inhibitory Effect of Black Radish Extract (Raphanus sativus L. var. niger) on Adipogenesis in 3T3-L1 Cells

The inhibitory effect of calcinated calcium on the growth of Escherichia coli O157:H7 during fresh radish (Raphanus sativus L.) sprout production was studied. It was revealed that the addition of 0.4% (wt/vol) calcinated calcium into radish sprouting medium which was artificially contaminated with E. coli O157:H7 (3.0 to 3.2 log CFU/ml) completely inhibited the growth or inactivated the microorganism. When radish seed extract was used instead of radish sprout production, the same extent of growth inhibition or inactivation was observed with much lower amounts (0.07%) of calcinated calcium under similar experimental conditions. The findings suggested that calcinated calcium may be useful to control E. coli O157:H7 contamination during the production of radish sprouts.

The aim of this study was to investigate the effect of aqueous extracts from Chenopodium album L. on germination and early stages of triticale grains (×Triticosecale Wittm. ex A.Camus) and radish seeds (Raphanus sativus L.). Germination indexes, fresh and dry mass, water content and electrolyte leakage were measured. Studies revealed the different germination capacity of triticale grains and radish seeds, where increased concentrations of allelopathins in aqueous C. album extracts significantly inhibited seedling growth for both species. The extracts had an inhibitory effect on the growth of seedling fresh mass. An increase in dry mass of radish seedlings was demonstrated for each of the extracts and, for triticale seedlings, only at concentrations of 0.5% and 1.5%. Water content in triticale and radish seedlings varied depending on the concentration of allelopathins in the extract. With increasing concentrations of C. album extract, regardless of seedling type, a statistically significant increase in electrolyte leakage was observed.

The Allelopathy phenomenon is an important component in a natural and an agro-ecosystems causing a stimulatory or inhibitory effect in crop production through the release of allelochemicals to the environment. In this study, the allelopathic effect on seed seed germination, seedling growth, fresh weight, dry weight, vigor index, total chlorophyll and carotenoid contents of radish (Raphanus sativus L.) and cucumber (Cucumis sativus L.) to the root exudates of Ageratum conyzoides L. (T1), Leucas aspera (Willd.) Link. (T2), Scoparia dulcis L. (T3), Spilanthes acmella L. (T4) and Vernonia patula (Dryand.) Merr. (T5) were studied in the laboratory. Results showed that the concentrated aqueous root exudates of T5 exerted highly reduced the effect of all the parameters as compared to control (distilled water) followed by T4. However, T2, T3, and T1 showed the least inhibitory effect on both the test crops. In comparison to cucumber, radish was more sensitive to inhibitory effects of aqueous root exudates of these five weeds. The result suggested that the root exudates may affect radish and cucumber seeds due to the inhibitory effect of allelochemicals which were present in the tested weeds.

Positive Effect

The effect of 2,6-dipyridinium selenabicyclo[3.3.1]nonandibromide (996 zh) on the level of lipid peroxidation (LPO), on the activity of glutathione reductase (GR) and on the morphometric parameters of oilseed radish seedlings under normal conditions and under stress (200 mmol NaCl) has been studied. It has been established that the substance 996 zh at a concentration of 100 μm exerted an antioxidant effect reducing the level of lipid peroxidation and increasing the activity of GR. In connection with that the germinating ability of seeds and the biomass of the roots and stems of seedlings increased, both under normal conditions and under stress conditions.The concentration of the substance 996 zh of 1000 μmol had a toxic effect, increasing the LPO level in normal conditions, but neutralized the effect of stress due to the addition of NaCl. This concentration had a slight inhibitory effect on germinability and on root development in seedlings. However, the same concentration of the substance 996 zh (1000 μmol) had a positive effect on the development of shoots under both normal and stressed conditions.
