GERGELIM EMBRAPA PDF

Mikakasa Data corresponding to the following variables were collected: According to Sharma et al. 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, This behavior demonstrates sesame sensitivity to both grrgelim and excess of water in the soil. Nevertheless, reduction in carotenoids combined embraap low content of chlorophyll gergepim in the leaves of plants subjected to both absence and excess of water may contribute to increasing the injuries to the photosynthetic mechanism, leading to limitations in growth, development and production. An evaluation of noninvasive methods to estimate foliar chlorophyll content. Total leaf area cm 2 was determined by measuring the length and width of leaflets and using the equation proposed by Silva et al.

Meztijind Irrigation management was performed using the water depth principle, based on the replacement of reference evapotranspiration ETo for two consecutive days. Da mesma forma, Amarante et al. Analyses were carried out using the statistical programs Sisvar 5. De acordo com Markwell et al. The spectral determination of chlorophylls a and b, as weel as total carotenoids, using various solvents with spectrophotometers of different resolution.

Journal Photosynthesis Research, v. For electrolyte leakage ELthe data of the sesame genotypes fitted to a decreasing linear model and maximum estimated value All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. 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, Water deficit is closely related to the loss of pigments and, consequently, to the reduction in the photosynthetic and productive capacity of plants.

An evaluation of noninvasive methods to estimate foliar chlorophyll content. Os dados corroboram os de Argenta et al. For the interaction irrigation depth x genotypes, there was no significance. Services on Demand Journal. Maximum yields found with intermediate water depths may be directly associated with the improvements observed in physiological and biochemical processes, such as the water content in the leaves.

Irrigation depth Li and irrigation time Ti were calculated according to Mantovani et al. Chlorophylls ab and total, and carotenoids were extracted using the solvent dimethyl sulfoxide Hiscox amp; Israelstam, Revista Brasileira de Fisiologia Vegetal, v. Cell membrane integrity evaluation, based on electrolyte leakage, was expressed as percentage of conductivity in relation to the total conductivity. Nevertheless, reduction in carotenoids combined with low content of chlorophyll a in the leaves of plants subjected to both absence and excess of water may contribute to increasing the injuries to the photosynthetic mechanism, leading to limitations in growth, development and production.

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.

Yield was estimated based on the production obtained in the evaluation area of the experimental plot. Juvenile growth in three vines in India. In natural environment, antioxidative responses to abiotic variations are induced by similar mechanisms, which result in adaptations to drier or more humid periods, to days with higher or lower light incidence, as well as to high and low temperatures, since these factors lead to the increase in ROS contents and, consequently, stimulate likewise antioxidant activity Gergslim et al.

Plants protect their cells and subcellular compartments from cytotoxic effects caused by ROS by using antioxidant enzymes, such as catalase and peroxidase. Along the experimental period, temperature, relative humidity, wind speed and rainfall data Table 1 were collected at the Embrapa Cotton Meteorological Station, in Barbalha-CE. Chlorophyll is one of the main factors related to plant photosynthetic efficiency and, consequently, to growth and adaptability to different environments and conditions caused by the various types of stress.

Chlorophyll meter evaluation for nitrogen management in corn. Forest Ecology and Management, v. Hence, analysis of photosynthetic pigments is essential to evaluate the health and integrity of internal cell apparatus during photosynthesis Taiz amp; Zeiger, ; Rigon et al. Sesame genotypes did not differ statistically and there were differences in the variables between the water replenishment rates.

Non destructive analysis of photosynthetic pigments in leaves of Sesamum indicum L. How to cite this article. At 50 DAE, leaf samples were collected to determine enzymatic activity: Thus, it is necessary to identify the physiological, biochemical and productive changes related to the tolerance to stress. Embrapz 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.

Gerfelim, biochemical and productive changes in sesame genotypes subjected to different rates of water replenishment. Data of the response variables were subjected to the analysis of variance by F test Fisher at 0. At 95 DAE, harvest was done manually by cutting the whole plant at soil level. Related Posts
