“…Reducing wheat seedling protein levels suggests that this herbicide prevents protein synthesis in wheat seedling stage. These results are in line with the results of experiments on the effects of butachlor herb on wheat and corn (Nemat Alla et al, 2008), oxyfluorfen on rice (Langaro et al, 2017) and paraquaton Azollamicrophylla (Sood, 2012). In another report with Imazethapyr doses on wheat, it was found that wheat germinating protein content decreased with increasing herbicide (Hoseiny Rad et al, 2011).…”

“…In a test with application of 0.5, 1 and 2 times the recommended dose of bentazon herb on peanut, the use of herbicides increased the content of proline in the leaf of this plant whereas with the increase of herbicide dose, the content of proline decreased (Khalaf et al, 2011). Research on the effect of herbicide oxyfluorfen (960 g ha-1) on rice plant revealed that this herbicide caused proline accumulation in plant tissues (Langaro et al, 2017). The researchers believed that the increase in proline was to remove ROS molecules from plant cells, thereby activating the plant's defense system (Molinari et al, 2007).…”

“…Since protein molecules exist in all the components of plant cells and play an important role, any reduction in protein levels will cause heavy damage to the growth and development of the plant (Langaro et al, 2017). In the early stages of seedling growth and emergence, the protein breakdown into amino acids is carried out to synthesize new enzymes, cell components, or transfer to the seedling seeding axis of the bud, and almost all of the protein storage of the seed will be used to grow the seed buds (Ashton, 1976).…”

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of herbicide) per kilogram of soil. The analysis of variance showed that the content of the main and auxiliary pigments of leaf, proline, sugar content, protein, activity of catalase enzymes, peroxidase, polyphenol oxidase, root and shoot dry weight were significantly affected by herbicide. The results showed the Imazethapyr herbicide stopped the production of valine leucine and isoleucine amino acids. As a result, the rapid reduction in the volume of these amino acids led to a reduction in protein synthesis in wheat plant. Therefore, the application of doses of 0.011, 0.022, 0.033 and 0.044 micrograms of herbicides decreased 14, 26, 44 and 47 percent of leaf protein content, respectively, compared with control treatment. Further, theapplication of these doses resulted in the reduction of 2.8, 5, 27 and 64% of activity of catalase enzyme, 3.5, 39, 49 and 52% peroxidase enzyme activity and 13, 24, 35 and 46% activity of polyphenol oxidase enzyme, compared with control treatment. The results revealed that Imazethapyr herbicide activates wheat antioxidant enzymes to reduce plant tolerance from damage caused by herbicide residues; therefore, it can be used as a marker or index of herbicide damage rate in physiological research.

“…No presente estudo foi demostrado aumento de 97,83% na atividade da POD em plantas com presença de mesotriona. A ação desta enzima evita a peroxidação lipídica e a degradação celular (Barbosa et al, 2014), corroborando com os valores obtidos em estudos com herbicidas seletivos, como o 2,4-D na cultura do trigo (Agostinetto et al, 2017) e o pré-emergente oxadiazon na cultura do arroz (Langaro et al, 2016).…”

RESUMOEste estudo objetivou avaliar a fitotoxidez do herbicida mesotriona no desenvolvimento inicial do milho inoculado com Azospirillum brasilense, associado à adubação nitrogenada. O delineamento utilizado foi o de blocos casualizados, em esquema fatorial 2x3, representado por milho com e sem aplicação do mesotriona (192 g ha) e os tratamentos: 1-inoculação das sementes com A. brasilense; 2-aplicação em cobertura de 140 kg ha -1 de N; e 3-A. brasilense + 140 kg ha -1 de N em cobertura aplicado aos 26 dias após a semeadura (DAS). A aplicação do mesotriona foi realizada aos 21 DAS, com avaliações realizadas por 28 dias após a aplicação (DAA). Aos 7 DAA constatou-se redução da taxa de assimilação líquida de CO 2 em 35% nas plantas que receberam aplicação de mesotriona, bem como aumento da atividade da peroxidase e maior degradação de carotenoides. Aos 14 DAA de mesotriona resultou em redução na taxa de assimilação líquida de CO 2 e na transpiração, enquanto aos 28 DAA foi verificado menor altura de plantas, área foliar e massa seca de parte aérea nas plantas com herbicida. A inoculação com A. brasilense + N elevou a atividade das peroxidases aos 7 DAA e auxiliou a manutenção da taxa transpiratória aos 14 DAA. Conclui-se que a inoculação com A. brasilense + N pode minimizar os efeitos danosos causados pelo mesotriona no desenvolvimento inicial do milho.Palavras-chave: bactérias promotoras de crescimento vegetal; herbicida; inibidor dos carotenoides; trocas gasosas Phytotoxicity of mesotriona in corn with Azospirillum brasilense associated nitrogen fertilization ABSTRACTThis study aimed to evaluate the phytotoxicity of the mesotrione herbicide in the initial development of maize inoculated with Azospirillum brasilense and associated with nitrogen fertilization. The treatments were: randomized blocks in a 2x3 factorial scheme, represented by maize with and without mesotrione application (192 g ha -1 ) and treatments: 1-inoculation of the seeds with A. brasilense; 2-Application in coverage of 140 kg ha -1 of N; And 3-A. brasilense + 140 kg ha-1 of N in cover applied at 26 days after sowing (DAS). The application of mesotrione was performed at 21 DAS, with evaluations performed up to 28 days after application (DAA). At 7 DAA a reduction of the net assimilation rate of CO 2 in 35% in the plants with mesotrione was observed, as well as increase of the peroxidases activity and greater degradation of carotenoids in the mesotrione plants. At 14 DAA the mesotrione reduced the rate of CO 2 net assimilation and transpiration, while at 28 DAA, lower plant height, leaf area and shoot dry mass were verified in herbicide plants. The inoculation with A. brasilense + N increased peroxidase activity at 7 DAA and helped maintain the transpiratory rate at 14 DAA. It is concluded that inoculation with A. brasilense + N can minimize the harmful effects caused by mesotrione in the initial development of corn.
