Such reduction in the activity of the enzymes in plants subjected to water stress conditions may be an indication of non-adaptation to embrxpa stressful environment, with effect on crop yield. Table 2 shows the analysis of variance summary for the growth physiological, biochemical and production variables.

Processo de elaboração de extrudados não expandidos (pellets) de milho e sementes de gergelim.

Evaluating the relationship between leaf chlorophyll concentration and SPAD chlorophyll meter readings. Biochemical and developmental characterization of multiple forms of Catalase in tobacco leaves.

Such behavior may indicate that sesame plants are more susceptible to the stress caused by excess of water than the one caused by its absence, corroborating the claim of Arriel et al. Revista Brasileira de Fruticultura, v. Their main characteristics include: Cell membrane integrity evaluation, based on electrolyte leakage, was expressed as percentage of conductivity in relation to the total conductivity.

This behavior demonstrates sesame sensitivity to both deficit and excess of water in the soil. How to cite this article.

In this context, it can be inferred that plants with lower contents of this pigment would be more subject to damages caused by the excess of light to the photosystem. Embrala water replacement in the soil resulted in decreases of Data corresponding to the following variables were collected: Nevertheless, in these regions, irrigation can be used to supplement rainfall, which leads to improvement in the growth, development and yield of crops. Objective of this study was to evaluate the physiological, biochemical and productive aspects of sesame genotypes as a function of different rates of water replenishment.

According to Bernardo et al. Quantitative factors irrigation depth were subjected to polynomial regression analyses, selecting the model of highest significance in the F test Ferreira, Conclusions Sesame genotypes did not differ statistically and there were differences in the variables between the water replenishment rates.

High contents of these compounds can reduce the activity of enzymes, cause peroxidation of lipids, oxidation of proteins and, in the most advanced stage, kill the cell Sharma et al. Chlorophylls ab and total, and carotenoids were extracted using the solvent dimethyl sulfoxide Hiscox amp; Israelstam, ABSTRACT The sesame crop has stood out due to the high nutritional content of its seeds, in addition to being able to be cultivated in the tropical and subtropical regions such as Northeast Brazil.

Results and Discussion Table 2 shows the analysis of variance summary for the growth physiological, biochemical and production variables. Revista Brasileira de Fisiologia Vegetal, v. Universal chlorophyll equations for estimating chlorophylls a, b, c, and d and total chlorophylls in natural assemblages of photosynthetic organisms using acetone, methanol, or ethanol solvents. Total leaf area cm 2 was determined by measuring the length and width of leaflets and using the equation proposed by Silva et al.

Da mesma forma, Amarante et al. Maximum yields found with intermediate water depths may be directly associated with the improvements observed in physiological and biochemical enbrapa, such as the water content in the leaves. O produtor pergunta, a Embrapa responde. Determining the content of carotenoids in plants subjected to some sort of embapa is very important, due to their role in the dissipation of the energy intercepted. These pigments act as photoprotectors, deactivating singlet and triplet oxygen by absorbing the energy present in these compounds during their formation, which prevents oxidative damages to plant cells Engel amp; Poggiani, ; Taiz amp; Zeiger, ; Brito et al.

Plants protect their cells and subcellular compartments from cytotoxic effects caused by ROS by using antioxidant enzymes, such as catalase and peroxidase. De acordo com Markwell et al. Simulating forest shade to study the development ecology of tropical plants: The experimental plot comprised four rows, and the two central rows were used for evaluations. Oil content in the seeds was quantified by nuclear magnetic resonance NMRbased on non-destructive tests, in which the value found results from the magnetic field scanning of the sample Oxford Instruments, Its production is directly associated with chlorophyll gerrgelim production Silva et al.

Maximum estimated activity In addition, yield reduction is directly related to the water stress conditions, because plants use the stomatal closure mechanism to protect themselves from water losses through transpiration, leading to a reduction in the photosynthetic gergelom Taiz amp; Zeiger, Data of the response variables were subjected to the analysis of variance by F test Fisher at 0.

Non-destructive analysis of photosynthetic pigments in cotton plants. Sesame genotypes did not differ statistically and there were differences in the variables between the water replenishment rates.

Depth L 3 Stress responses in plants: The sesame genotypes used were white and creamcolored, all developed by the Brazilian Agricultural Research Corporation Embrapa Cotton. In this context, sesame oil content becomes one of the most important variables to evaluate the feasibility of the crop from the agronomic point of view.

Irrigation depth Li and irrigation time Ti were calculated according to Mantovani et al. At 95 DAE, harvest was done manually by cutting the whole plant at soil level.
