“…The content of proline, a protective solute in teak leaves increased due to drought treatment in both the clones studied. Proline is an amino acid and known to act as an osmolyte, protecting the plasma membrane integrity (MANSOUR, 1998), as a sink of energy or reducing power (VERBRUGGEN et al, 1996), as a scavenger of ROS and their derivatives (HONG et al, 2000;BASHIR et al, 2007) and as a source for carbon and nitrogen (PENG et al, 1996), and thereby helping the plants to tolerate stress effects (MANIVANNAN et al, 2007). In the present teak clonal materials proline accumulation thus appears to be related to mechanisms associated with tolerance to desiccation (MANIVANNAN et al, 2007).…”

Summary Four-year old clones (FG1 and FG11) of teak (Tectona grandis Linn. f.), differing in rejuvenation capacity were grown in glazed earthenware pots. Drought treatments were imposed by withholding water for 20 days and rewatered to the field capacity daily for 5 days and the possible role of biochemical alteration and antioxidant metabolism in conferring photosynthetic capacity was determine by measuring photosynthetic traits, cellular damage and assaying activities of the superoxide dismutase (SOD) and peroxidase (PER) enzymes. Growth, relative water content (RWC), net photosynthetic rate (Pn), stomatal conductance (gs), chlorophyll fluorescence (Fv/Fm) and chlorophyll a, b, total chlorophyll and soluble protein content decreased significantly with increasing drought treatments from 5 to 20 days. Droughtinduced stress significantly increased the carotenoids content, relative electrolyte leakage and malondialdehyde (MDA) content, and, at the same time, accumulated free proline, free amino acid and soluble sugars in both clones. After re-watered to the field capacity daily for 5 days, both clones were shown significant recovery in the studied parameters. As compared with the FG11, the FG1 clone was more tolerant to drought as indicated by higher level of antioxidant enzyme activities as well as lower MDA content and electrolyte leakage. Similarly, drought stress caused less pronounced inhibition of Pn in FG1 than in FG11 clone. After re-hydration, the recovery was relatively quicker in FG1 than in FG11 clone. FG1 clone showed significant recovery in maximum quantum yield or photochemical efficiency of PSII (Fv/Fm) after 5 days of re-watering. The FG11 compared to the FG1, the former clone was less tolerant to drought than the latter. These results demonstrated that the different physiological strategies including antioxidative enzymes employed by the FG1 and FG11 clones of T. grandis to protect photosynthetic apparatus and alleviate drought stress. Furthermore, this study also provides ideas for teak improvement programmes and may be useful in breeding or genetic engineering for their tolerance to drought stress.

“…Besides, insecticides triggered oxidative stress by producing reactive oxygen species (ROS), e.g., superoxide anion radical (O 2 Á-) and H 2 O 2 (Mishra et al 2008). Insecticide-induced oxidative stress was shown to alter the cellular redox balance by altering ascorbate-glutathione (Asc-Glu) cycle or damaging other antioxidant defense systems (Bashir et al 2007b). Plants have multiple strategies to confer their tolerance to insecticide-induced toxicity, and prevention of oxidative damage to cells has been suggested as one of the mechanisms of stress tolerance (Saraf and Sood 2002;Prasad et al 2005).…”

The aim of the present study was to analyze the alterations in the, antioxidant enzyme activities (such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and level of glutathione (GSH) and lipid peroxidation (LPO) of wheat acutely treated with CP and DM treatments at low, high doses and their combination. CP and DM were administered to wheat in different doses of 1, 1.5, 5 and 35 mg kg -1 given alone and combination. After 3 weeks, antioxidant enzyme activities, and the level of GSH and LPO were recorded and analyzed. Antioxidative defense mechanisms and LPO in wheat display different responses depending on different pesticide treatments and doses. Biochemical analysis showed that exposure of the CP and DM cause plant tissue damage. It is suggested that appropriate ecotoxicological risk assessment should be made in the areas where DM is proposed to be used in pest control when compared to CP. In the present study, we also concluded that the effect of the combined of CP and DM on the oxidative stress may be synergistic.
