“…Um grupo de sete plantas, incluindo Menta pulegium L. foi selecionado por afetar a germinação de Lactuca sativa (Shiraishi et al, 2002 Investigações mais amplas, incluindo outras metodologias experimentais, principalmente testes em condições de campo, que evidenciem os efeitos de espécies com potencial alelopáticos são necessárias. Tais estudos tornam-se de extrema importância, uma vez que a utilização destas espécies pode contribuir na inibição de plantas espontâneas e na determinação de manejos mais adequados (Carvalho et al, 1996).…”

“…Os monoterpenos, componentes majoritários dos óleos essenciais de um grande número de espécies, tem sido relatados como aleloquímicos eficazes pelo efeito tóxico sobre a germinação de sementes (Souza Filho et al, 2009), crescimento de bactérias (Arruda et al, 2006) e sobre o crescimento de alguns fungos patogênicos através do pré-planto (Hasse et al, 2007). Os monoterpenos podem causar extensivos danos às membranas e ao processo respiratório das células, uma vez que podem ser sequestrados pelas estruturas secretoras das mesmas (Gershenzon et al, 2000).…”

RESUMO:Objetivou-se com esse trabalho avaliar a interferência de possíveis efeitos alelopáticos de Mentha x villosa Huds. sobre a emergência de Lactuca sativa L. As atividades foram conduzidas em laboratório, no Instituto de Ciências Agrárias (ICA) da Universidade Federal de Minas Gerais, em Montes Claros/MG. Foram propostos três tratamentos, sendo esses: solo A, coletado em área cultivada com hortelã no horto medicinal do ICA/UFMG; solo B, coletado em áreas adjacentes e, testemunha (papel germiteste).O delineamento experimental foi inteiramente casualizado (DIC), com sete repetições. As variáveis avaliadas foram: porcentagem e índice de velocidade de emergência. Observou-se que a emergência de plântulas de Lactuca sativa foi significativamente afetada pelo solo A (6,95%) se comparada com o solo B (21,71%), representando assim, uma inibição da emergência, ou seja, efeito alelopático da hortelã sobre a emergência de alface. Já o índice de velocidade de emergência (IVE) não diferiu significativamente entre os solos testados. Palavra-chave: alelopatia, germinação, plantas medicinaisABSTRACT: Allelopathic influence of mint (Mentha x villosa Huds.) on the emergence of lettuce (Lactuca sativa L.) seedlings. This study aimed to assess the interference of possible allelopathic effects of Mentha x villosa Huds. on the germination of Lactuca sativa L. The activities were carried out in laboratory, at the Institute of Agricultural Sciences (ICA) of the Federal University of Minas Gerais, Montes Claros, Minas Gerais State, Brazil. The following three treatments were proposed: soil A, collected in area cultivated with mint at the garden of ICA; soil B, collected in adjacent areas; and control (germitest paper). Experimental design was completely randomized (CR), with seven replicates. The evaluated variables were: germination percentage and speed index. The emergence of Lactuca sativa seedlings was significantly affected by soil A (6.95%) when compared to soil B (21.71%), indicating thus emergence inhibition, i.e. an allelopathic effect of mint on lettuce emergence. On the other hand, the germination speed index (GSI) did not differ significantly between the tested soils.

“…Agar substrates alone are used as untreated controls (Fujii, 1994). Shiraishi et al (2002) used this method to screen the allelopathic activity of leachates from seventyone plant leaf residues and found at least seven species that inhibited the growth of lettuce seedlings by more than 50%.

-Known since ancient times, the phenomenon of allelopathy has recently received greater attention from researchers and farmers worldwide. Crop failures and low yields caused by the reseeding, overseeding, crop rotation and replanting of fruit trees in orchards are believed to be caused by allelopathic activity. Moreover, the expensive and environmentally impacting herbicides for weed control have motivated studies directed at developing cheaper, environmentally-friendly alternatives. Despite the difficulties in separating chemical interference from other mechanisms, more modern approaches have produced consistent and conclusive data on this topic. The release and dynamics of allelochemicals in the soil are discussed herein. Examples of allelopathic crops, the allelochemicals produced and their uses in cropping systems are also presented along with current research trends regarding allelopathy. allelopathy / chemical interference / agriculture / potential use

“…preta respectively when 10 mg oven-dried leaves were used. Shiraishi et al, [23] reported lettuce hypocotyl stimulation by Oxalis tuberosa, Artemisia capillaris, and Coreopsis tinctoria to 130%, 120%, and 110% respectively for 10 mg oven-dried mucuna leaves treatment. Allelopathic effects by the leaf leachates among all the genotypes varied significantly from the control with Mucuna pruriens GA/94/002 having the most significant inhibition on lettuce radicle (12% of the untreated control).…”

The study was conducted to test allelopathic effects of some Mucuna pruriens on the germination and growth of lettuce. The effects of root exudates and leaf leachates of eight mucuna genotypes; Mucuna pruriens var. utilis cv. cinza, Mucuna pruriens var. utilis cv. preta, Mucuna pruriens var. utilis cv. hassjo, Mucuna pruriens var. utilis cv. fvb, Mucuna pruriens 82/507, Mucuna pruriens 82/508, Mucuna pruriens 82/116, and Mucuna pruriens GA/94/002 were tested on the germination, radicle, and hypocotyl elongations of lettuce (Lactuca sativa var. Great Lakes 366). The effects of leaf leachates and root exudates of mucuna were tested using sandwich and plant-box methods respectively with lettuce as the receptor plant. Roots exudates inhibition varied significantly among genotypes (94.3%-98.5%). Root exudates of Mucuna pruriens var. utilis cv. fvb had the maximum inhibition (98.5%). Lettuce radicle inhibition gradually decreased with distance from the mucuna plant in a plant-box and with high correlation (r=0.910-0.952; p<0.05) between lettuce radicle inhibition and distance from mucuna roots. The effect of 50 mg oven-dried mucuna leaves had significant inhibition on lettuce radicle elongation (12.0%-15.8% of untreated control). Leaf leachates had less effect on the hypocotyl elongation of lettuce (50.5%-72.0% of untreated control) at the same application of ovendried leaves (50 mg/10 ml agar).
