“…1A). This variation may be related to seasonality, since the metabolism of phenylpropanoids and flavonoids was stimulated by lower temperatures (Grace et al, 1998;Rodziewicz et al, 2014). This fact was verified in the present study, in which the highest values of TSP coincided with the time of lower environmental temperatures (Fig.…”

The sweet cassava root age and pre-harvest managements can modulate the oxidative metabolism and provide a longer shelf life. Moreover, the evaluation of enzymes envolved in oxidative protection regarding the phenolic metabolism can be an additional approach to understand how the cultivation affects the post-harvest physiological deterioration tolerance in sweet cassava roots. Thus, the aim of this study was to evaluate the oxidative enzymatic protection associated to oxidation mediate by PPO and POD, in response to population density and harvest time of sweet cassava roots, cv. "Mossoró". The roots were cultivated in field conditions in the Brazilian Semiarid, under irrigation. The experimental design was a randomized complete block with three replications. Treatments corresponded to four harvest times (240, 300, 360, 420 days after planting -DAP) and four population densities (10,000, 12,500, 15,000 and 17,500 plants ha -1 ). Sweet cassava roots were sampled and the total soluble phenol content as well as soluble protein content were measured. Also, polyphenol oxidase (PPO), peroxidase (POD), superoxide dismutase (SOD), catalase (CAT) activity was evaluated. The roots showed higher total soluble phenol content at 300 and 360 DAP and higher protein content at 240, 300 and 360 DAP, for all densities avaluated. Planting densities extremes, of 10,000 and 17,500 plants ha -1 , resulted in higher levels of phenolics compounds and SOD activity. However, did not promote difference in the levels of soluble proteins. There was a significant reduction at PPO, SOD and CAT activity with late harvest, which did not occur for POD activity. Therefore, younger roots have higher oxidative enzymatic protection when compared to older roots in Semiarid conditions.

“…The photosynthesis rate usually decreases during exposure to several stress sources in superior plants (Chaves et al, 2009). The main reason is the stomatal closure, which leads to the decrease in the internal concentration of CO 2 and can lead to the transfer of electrons to O 2, one of the main causes of production of ROS (Rodziewicz et al, 2014). This variable can be influenced by the application of herbicides and environmental factors such as water availability, light and energy (Ometto et al, 2003).…”

Biochemical and Physiological Changes in Rice Plants Due to the Application of Herbicides1

et al. 2016

-The application of herbicides, even if selective, can cause biochemical and physiological changes, resulting in oxidative stress. This stress comes from the accumulation of reactive oxygen species produced due to exposure to the herbicide. However, plants have developed defense strategies, which can be enzymatic or non-enzymatic. The objective of this study was to evaluate the morphological and metabolic changes such as photosynthetic parameters, oxidative damage and antioxidant enzyme activity of rice plants after applying herbicides. For this, a study was conducted in a greenhouse and laboratory and the treatments consisted of application of imazapic + imazapyr, quinclorac, bentazon, cyhalofop-butyl, penoxsulan, bispyribac-sodium and carfentrazone-ethyl, in addition to control without herbicide. The phytotoxicity in plants was strong and there was a reduction in photosynthesis, stomatal conductance and efficiency of water use in plants treated with carfentrazone-ethyl. Furthermore, the application of carfentrazone-ethyl resulted in lower chlorophylls and carotenoids and increased lipid peroxidation and proline accumulation. Changes in the activity of enzymes belonging to the antioxidant system were inspected by applying herbicides. The application of herbicide alters the physiology of rice plants, triggering responses to oxidative stress, which are more pronounced when used carfentrazone-ethyl. Keywords:Oryza sativa, oxidative stress, lipid peroxidation, selectivity. RESUMO -

“…Thus, another marked gene expression signifying the establishment of stress at cellular level is the elucidation of heat shock protein (Hsp). In earlier literature different classes of Hsp are marked as cellular indices to perceive the metal stress in crop plants (Rodziewicz et al, 2014). Interestingly, Salvinia being an aquatic pteridophyte is a no exception when it recorded a distinct variation of heat shock protein after 7 days of incubation under gradient of Al concentrations.…”

In the present Investigation Salvinia natans L exposed to increasing concentration of Al stress and its interaction with polyamine was discussed. Among the physiological attributes Glutathione-S-transferase, glutathione peroxidase activities were up regulated against control. At transcript level glutathione peroxidase was also shown by over-expressed manner to support the lyses of peroxide. However, the application of Put had minimized these activities with same way to establish the role of polyamine under metal stress. In secondary metabolites synthetic pathway phenyl alanine ammonia lyase recorded a steady increase although the concentration of Al. Not only a single fraction of polyamine was responsible under Al stress but also pool of conjugated polyamine was up regulated. In oxidation of polyamine the activity of diamine oxidase (DAO) was more under metal stress to induce accumulation H2O2. In compensation for cellular depletion of reduced glutathione, dihydro ascorbate reductase activity was up regulated in plant under stress. At cellular level plants were distinctly marked with variations in heat shock proteins and established as a possible biomarker for Al toxicity. The study possibly established the affectivity in biomonitoring of Al in field condition with exercise cellular responses of Salvinia plants.
