“…the accumulation of mda was measured as a sign of lipid peroxidation because mda is one of products of lipid peroxidation and the result of cell membrane injury [2,45]. the increase in mda content of maize leaves may be due to the increase in ros levels induced by diuron.…”

the effects of diuron, a photosystem ii inhibiting herbicide, on lipid peroxidation, photosynthetic pigments, soluble protein, proline contents and some antioxidant enzymes in maize leaves were studied and protective effects of polyamines against diuron toxicity were investigated. Diuron significantly increased lipid peroxidation, suggesting oxidative damage in the plants and proline content, while it decreased total chlorophyll, carotenoid and soluble protein levels in the leaves during the experiments. Pretreatment with polyamines statistically decreased lipid peroxidation induced by diuron and spermine (sPm) proved to be the most effective polyamine. Also, pretreatment with polyamines significantly prevented the losses of total chlorophyll, carotenoid and soluble protein induced by diuron. on the other hand, pretreatment with polyamines significantly increased proline contents of the leaves in comparison with the leaves treated with diuron. superoxide dismutase (sod), guaiacol peroxidase (GPX) and glutathione reductase (Gr) activities increased in the leaves treated with diuron while catalase (cat) activity decreased. Pretreatment with spermidine (SPD) did not change significantly SOD activity at 24 and 72 hrs of diuron treatment but prevented the increase in sod activity induced by diuron at 48 h. however, pretreatment with sPd increased GPX activity at 24 h and GR activity at 48 and 72 hrs. CAT activity in the leaves pretreated with SPD was similar to that of the leaves treated with diuron. Pretreatment with sPm prevented the increase in sod activity induced by diuron at 48 h but significantly increased it at 72 h of diuron treatment. However, pretreatment with SPM did not significantly change GPX and GR activities during the experiments but reversed the decrease in CAT activity induced by diuron at 72 h. Pretreatment with putrescine (PUT) prevented the increase in SOD activity induced by diuron at 48 and 72 hrs while it increased GPX and GR activities at 48 h of diuron treatment. Also, the decrease in CAT activity induced by diuron at 72 h was completely prevented by Put. it can be concluded that pretreatment of maize leaves with polyamines reduced the damage produced by diuron and the protective effects of polyamines against diuron toxicity were closely associated with antioxidant system.

“…In the 24-h treatment, the peroxidase and MDA exhibited crosstalk because of the protection from membrane damage exhibited by L. minor [67]. Beker Akbulut and Yigit (2010) reported that in the ATR treatment groups, the POD activity and malondialdehyde (MDA) content decreased after the 10th day, whereas the APX activity decreased on the 15th day [68].…”

Herbicides adversely affect both the target plant and its environment. In this study, Helianthus annuus L. cv. "Oliva CL" was treated post-emergence with 0.3 to 3.1 mM quizalofop-p-ethyl. The peroxidase activity (POD), ascorbate peroxidase activity (APX), lipid peroxidation, pigment system and total phenolic content were then determined on the 1st, 5th, 10th and 15th days following treatment. The POD activity increased on all application days, and the APX activity increased on the 5th day and decreased on the 10th and 15th days. In addition, the malondialdehyde (MDA) content was increased on the 1st, 5th, 10th and 15th days, except for the in H. annuus plants treated with 1.6 to 3.1 mM quizalofop-p-ethyl. The total chlorophyll, carotenoid and total phenolic content were important and changed in a time dependent manner. In the present study, we also investigated the possible role of salicylic acid (SA) in protecting H. annuus seedlings from herbicide toxicity. The plants were first treated with 0.5 mM SA pre-emergence and then treated with 0.3 to 3.1 mM quizalofop-p-ethyl herbicide post-emergence. In general, increases in the POD activity and MDA content were observed in the treatment groups on all application days. In the treated groups, the APX activity increased until the 15th day. In the SA pre-treated plants, the total phenollic, total chlorophyll and carotenoid content were also important in a time dependent manner.

“…Keywords: Paspalum virgatum L., chemical control, phytotoxicity, biological response, triazine 3/12 A atrazine é utilizada em pré e pós-emergência inicial, no controle de dicotiledôneas e algumas gramíneas, pertence ao grupo das triazinas, sendo inibidor do Fotossistema II (Girotto et al, 2011). Os sintomas de fitotoxicidade apresentados com a aplicação deste herbicida são clorose seguida de necrose, devido a interrupção no fluxo de elétrons da fotossíntese, levando a morte da planta (Akbulut e Yigit, 2010). Pode inibir também a germinação de sementes de plantas daninhas (Merini et al, 2009).…”

O Paspalum virgatum L. é uma planta daninha comum de pastagens e possui difícil controle, principalmente devido sua semelhança com as forrageiras. As técnicas convencionais como gradagem e replantio da pastagem têm sido insatisfatórias no controle desta planta daninha. O objetivo deste trabalho foi avaliar o controle do capim-navalha (P. virgatum L.) à atrazine aplicada em pré-emergência, por meio de curva dose-resposta e a seletividade deste herbicida nas pastagens de Brachiaria brizantha cv. Marandu e Panicum maximum cv. Mombaça. Foram realizados três experimentos independentes, com cada espécie, em dois tipos de solo (Latossolo Vermelho Amarelo distrófico - LVAd de textura franco-argilosa e Argissolo Vermelho Amarelo distrófico - PVAd de textura franca), utilizando a escala percentual de notas para verificar o controle do capim-navalha e a fitotoxicidade nas forrageiras e massa seca no final dos experimentos. A atrazine controlou o capim-navalha, desde os 15 dias após a aplicação (DAA), nas doses abaixo da recomendação do fabricante (250 e 500 g ha-1 i.a.). Contudo, apesar dos sintomas de fitotoxicidade causados pela atrazine, houve retomada de crescimento aos 60 DAA tanto para B. brizantha cv. Marandu quanto para P. maximum cv. Mombaça. Houve menor fitotoxicidade às pastagens no solo de textura franco‑argilosa em relação ao solo de textura franca. A atrazine proporcionou controle eficiente do P. virgatum L. (500 g ha-1 i.a.) quando aplicada em pré-emergência e seletividade para B. brizantha cv. Marandu (<2.000 g ha-1 i.a.) e P. maximum cv. Mombaça (<500 g ha-1 i.a.).
