For the content of carotenoids, maximum estimated value 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 emnrapa al.

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

According to Sharma et al. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. Objective of this study gergrlim to evaluate the physiological, biochemical and productive aspects of sesame genotypes as a function of different rates of water replenishment. The spectral determination of chlorophylls a and b, as weel as total carotenoids, using various solvents with spectrophotometers of different resolution.

Non destructive analysis of photosynthetic pigments in leaves of Sesamum indicum L.

Methods in comparative plant ecology, London: Oil content in the seeds increased with the increment in water replacement until the estimated water depth of Embraapa Sesame genotypes did not differ statistically and there were differences in the variables between the water replenishment rates. Photosynthetic pigments, nitrogen, chlorophyll a fluorescence and SPAD readings in coffee leaves.


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. Their main characteristics include: Plants protect their cells and subcellular compartments from cytotoxic effects caused by ROS by using antioxidant enzymes, such as catalase and peroxidase. To ggergelim Brazilian Agricultural Research Corporation Embrapa Cotton for providing the structure needed to conduct this study.

Quantitative factors irrigation depth were subjected to polynomial regression analyses, selecting the model of highest significance in the F test Ferreira, O produtor pergunta, a Embrapa responde. Tillage in the experimental area consisted in one plowing and four cross harrowing procedures, using a leveling harrow. For electrolyte leakage ELthe data of the sesame genotypes fitted to a decreasing linear model and maximum estimated value How to cite this article.

Literature Cited Arriel, N.

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. The sesame crop is resistant to drought and can produce with mm of water well distributed along the cycle Bernardo et embbrapa.

The reductions in RWC observed here were lower than those reported by Pinto et al. Chlorophylls ab and total, and carotenoids were extracted using the solvent dimethyl sulfoxide Hiscox amp; Israelstam, This behavior demonstrates sesame sensitivity to both deficit and excess of water in the soil.


Nonetheless, increment in water depth above 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. Activation of systemic disease resistance in pea by an avirulent bacterium or a benzothiadiazole, but not by a fungal leaf spot pathogen.

Chlorophyll bconsidered as accessory pigment, is a biochemical compound present in the chloroplasts that help light absorption. Physiological, biochemical and productive changes in sesame genotypes subjected to different rates of water replenishment. Data corresponding to the following variables were collected: Adaptation and acclimation mechanisms.

For soil chemical characterization, according to the methodology of Carmo et al. 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.
