“…This inhibition in both seed germination and seedling growth of the target species corroborates with germination and growth (Turk et al, 2005) of alfalfa and radish. Furthermore, the results are in agreement with the literature in the fact that the inhibitory effect is dependent on the extract concentration (Turk et al , 2005Ghareib et al, 2010;Hegab & Ghareib, 2010). The data showed that the type of solvent used in the extract was important.…”

Allelopathic effect of black mustard tissues and root exudates on some crops and weeds

-Laboratory and greenhouse experiments were conducted to evaluate the phytotoxic effect of black mustard extracts and root exudates on two crops: Trifolium alexandrinum and Triticum aestivum, and two weeds: Phalaris paradoxa and Sisymbrium irio. The seeds were treated with aqueous and ethanolic extracts and chloroform for eight days, or subjected to root exudates of just harvested mustard in a greenhouse for five weeks. High-performance liquid chromatography (HPLC) was used to quantify phytotoxins from plant tissues. Seed germination of P. paradoxa was reduced with the lowest concentration of the different extracts. However, the aqueous extract at 4% completely curtailed the germination of all the target species. In general, plant extracts had a concentration-dependent reduction of seedling growth of the target species. However, the ethanolic extract, at the lowest concentration, has stimulated the shoot length of both T. alexandrinum and T. aestivum, and the root length of the former. Mustard root exudates inhibited emergence and growth of the target species throughout the experiment. Ferulic and syringic acids were the dominant allelochemicals found when HPLC was used.Keywords: allelopathy, Brassica nigra, plant extracts, isothiocyanates (ITCs), phenolic acids.RESUMO -Experimentos de laboratório e estufa foram realizados para avaliar o efeito fitotóxico dos extratos de mostarda-preta e exsudatos de raiz de duas culturas: Trifolium alexandrinum e Triticum aestivum, bem como de duas plantas daninhas: Phalaris paradoxa e Sisymbrium irio. As sementes foram tratadas com extratos aquosos, etanólicos e clorofórmio por oito dias, ou submetidas a exsudatos de raiz de mostarda recém-colhidaem estufa durante cinco semanas. A cromatografia líquida de alto desempenho (HPLC) foi usada para a quantificação de fitotoxinas a partir de tecidos de plantas. Sementes de P. paradoxa apresentam germinação reduzida com a menor concentração dos diferentes extratos. No entanto, o extrato aquoso a 4% restringiu completamente a germinação de todas as espécies-alvo. Em geral, os extratos de plantas tiveram uma redução, dependendo da concentração do crescimento de mudas das espécies-alvo. No entanto, o extrato etanólico, na concentração mais baixa, tem estimulado o comprimento dos ramos de T. alexandrinum e T. aestivum e o comprimento da raiz da primeira. Exsudatos de raiz de mostarda inibiram o surgimento e crescimento das espécies-alvo durante todo o experimento. Os ácidos ferúlico e siringico foram os aleloquímicos dominantes encontrados utilizando HPLC.Palavras-chave: alelopatia, Brassica nigra, extratos vegetais, isotiocianatos (ITCs), ácidos fenólicos.

Effect of Aqueous Extracts from Weed Species on Germination and Initial Growth in <i>Raphanus sativus</i> L.

The current paper presents the results of a study on the effects of aqueous extracts from five weed species (Amaranthus retroflexus, Cirsium arvense, Convolvulus arvensis, Echinochloa crus-galii, Setaria verticillata) on germination and initial growth in Raphanus sativus L. The following indicators have been analyzed: indices of germination (the germination percentage; the speed of germination; the speed of accumulated germination and the coefficient of germination rate), the length of the root and hypocotyls, the pH of aqueous extracts, the UV-Vis absorption spectra of aqueous extracts. The results of the investigations showed the following aspects: the aqueous extracts reduced the values of calculated germination indices and root growth in the first ontogenetic stages of the test species; the pH of the extracts was slightly acid to neutral. Qualitative spectrophotometric analysis indicated the possible presence of phenolic and organic compounds in the extracts. C. arvense, S. verticillata and E. crus-galii presented the most pronounced effect on germination and growth processes.

“…Affecting many physiological processes and the effect on ion uptake these allelochemicals reduce seed germination and seedling growth [1,3] inhibits plant growth. Thus, it was thought that allelochemicals are important factors in the success of many invasive plants for establishing virtual monoculture and may contribute to the ability of particular invasive species to become dominant in invaded plant communities [4,5].…”

The effects of different methanol extracts of Convolvulus arvensis on phytohormones (indole acetic acid (IAA), gibberellic acid (GA), abscisic acid (ABA) and salicylic acid (SA)) levels of corn were investigated. It was observed that all concentrations of methanol extracts (50 µl, 75 µl, 100 µl) of roots, stems and leaves of C. arvensis decreased the mitotic index and also caused abnormalities in chromosomes. On the other hand, phytohormone levels have been changed by application of different extracts at various concentrations. Compared with the control, GA levels decreased significantly whereas ABA levels increased in all the application groups. SA and IAA levels showed changes depending upon applied extracts and their concentrations.
