“…As can be seen in Tables 1-4 in which the crude extract of Persea venosa stem bark significantly inhibited (p < 0.05) the germination of corn, soybean, lettuce and radish seeds, and the germination varied significantly inversely proportional to the concentration of this crude extract (Mendes et al, 2013).

The inappropriate use of herbicides has increased the resistance of weeds; thus, the study of allelopathy becomes of paramount importance. The ability of certain plants to interfere with the metabolism of others by means of substances released into the environment, either by their aerial or roots system, becomes an alternative to combat invasive plants, dispensing with or reducing the use of herbicides. The objective of this work was to evaluate the plant species most sensitive to the allelopathic potential of aqueous extracts. One of the plant species studied was lettuce because it had a rapid response potential, thus showing the benefits obtained through allelopathy.

“…Corroborando com esse resultado, o aumento da concentração de extrato de Persea venosa promoveu um efeito negativo ao comprimento das raízes mais significativo, do que ao comprimento da parte aérea do milho em trabalho realizado por Mendes et al (2013). Estudo avaliando o potencial alelopático de extratos orgânicos das folhas de Pyrostegia venusta sobre sementes de pepino, evidenciou que o comprimento do hipocótilo foi afetado pelos extratos hexânico e metanólico, apresentando efeitos inibitórios sobre o crescimento da parte aérea da planta (Silva et al, 2011).…”

RESUMO:O presente estudo teve como objetivo analisar o efeito alelopático e o rótulo dos produtos vegetais contidos nas garrafadas comercializadas no mercado municipal de Montes Claros -MG. Adquiriram-se oito garrafadas que foram utilizadas para tratar, cada uma, 20 sementes de alface (Lactuca sativa L.) dispostas em placas de Petri sobre papel saturado com 4mL do conteúdo de cada garrafada em 04 concentrações: 12,5; 25; 50; e 75%. O controle positivo foi realizado com solução de sulfato de zinco a 1%, além dos controles: água mineral, água da torneira, e água destilada. As placas de Petri foram lacradas com filme plástico, cobertas com saco plástico e incubadas em escuro por sete dias à temperatura média de 27,2°C e na umidade média de 54%. Após 7 dias, mediu-se o comprimento da radícula e do hipocótilo (mm) de cada uma das plântulas e quantificou-se o número de sementes que germinaram. Os dados foram submetidos à análise de variância pelo software Sisvar, sendo os resultados comparados pelo Teste Scott-Knott ao nível nominal de 5%. Os resultados do teste de germinação indicaram que houve efeito significativo das garrafadas sobre a germinação das sementes de Lactuca sativa L., onde o percentual de germinação das sementes foi inversamente proporcional ao aumento da concentração das garrafadas. Portanto, observou-se que as garrafadas apresentaram potencial alelopático ao inibirem a germinação das sementes de alface.Palavras-chave: alelopatia, plantas medicinais, rotulagem de produtos, alface. ABSTRACT: Allelopathic effect and analysis of bottle labels commercialized in the municipal market of Montes Claros -MG.This study aimed to analyze the allelopathic effect and label of plant products put in bottles commercialized in the municipal market of Montes Claros -MG. Eight bottles were employed to treat, each one, 20 lettuce seeds (Lactuca sativa L.) placed at Petri plaques over saturated paper with 4mL of the content of each bottle in 04 concentrations of 12.5; 25; 50; 75% for each bottle, 1% of zinc sulfate solution (positive control) and 3 negative control groups (containing mineral water, tap water and distilled water). The Petri plaques were sealed with plastic film, covered with plastic bag and incubated in the dark for seven days at an average temperature of 27.2°C and average humidity of 54%. After 7 days, it was measured the length of the radicle and the hypocotyl (mm) of each one of the seedlings and the number of seeds that germinated was quantified. The data were submitted to analysis of variance by Sisvar software and the results were compared by Scot-Knott Test at a nominal level of 5%. The results of the germination test indicated that there was a significant impact of the bottles in the germination of the lactuca sativa L. seeds, where the percentage of seeds germination was inversely proportional to the concentration increase in the analyzed bottles. Therefore, it has been observed that the bottles presented allelopathic potential when they inhibited the germination of lettuce seeds.
