“…Slight decrease at 0.1 lM and increase at 0.5 lM HBR treated material in catalase activity was observed; however, decrease at 0.1 lM HBR and gradually increase at 0.5 and 1 lM HBR detected in peroxidase activity. There are few reports on antioxidant system and BR connections (Mazorra et al 2002;Ozdemir et al 2004;Hayat et al 2007). Mazorra et al (2002) using tomato leaf dics observed stimulation in SOD activity at 25 and 40°C for POX activity only at 40°C.…”

“…Recently, several BR-regulated genes associated with diverse physiological responses, such as cell division and expansion, differentiation, programmed cell death, stomatal development and functions, homeostasis and gene expression have been isolated by genome-wide microarray analysis (8,27). Mazorra et al (15) reported the ability of brassinosteroids in imparting drought tolerance in groundnut.…”

“…A mechanism that may be involved in the resistance to many types of stress is the increased activity of the antioxidant pathway. High concentrations of antioxidant enzymes have been found in response to abiotic stress, and they may be involved in the acquisition of tolerance to different types of environmental stress [50]. Therefore, measuring the enzymes of the antioxidant defence systems can be an indirect method of evaluating plant oxidative stress [10] [11] [51].…”

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.
