Relative chlorophyll contents in the evaluation of the nutritional status of nitrogen from xaraes palisade grass and determination of critical nitrogen sufficiency index

ABSTRACT The objective of this study was to verify the efficiency of two portable chlorophyll meters (Minolta SPAD® 502 and Falker ClorofiLOG® 1030) in assessing the nutritional status of wheat plants, correlating the indices from the devices and the direct determination of chlorophyll content with the concentration of nitrogen (N) in the plant. The experiment was conducted in a greenhouse, in pots with 5 dm3 of Oxisol, in a completely randomized design, with six N doses (0, 80, 160, 240, 320 and 400 mg dm-3) and five replicates. At 47 days after emergence, the readings of SPAD and Falker indices and the quantification of chlorophyll content and N concentration in wheat plants were performed, as well as analysis of variance and correlation test, both at 0.05 probability level. The chlorophyll meters Minolta SPAD® 502 and Falker ClorofiLOG® 1030 do not differ with respect to the indirect determination of chlorophyll in wheat plants. The Falker chlorophyll index was statistically equal to the chlorophyll content. Indirect chlorophyll indices and chlorophyll content showed a high correlation with the N concentration in the plant.

Household Allocation

This article presents a theoretical framework for answering the question, Does women's income-producing work result in an improvement or a deterioration in the health and nutritional status of their children? The author maintains that the literature has not provided clear evidence that the children of working mothers have lower nutritional status than those of mothers who do not work outside the home. She notes that previous studies have not controlled either for the family's income level or for other important variables, such as the presence of an employed male and land tenure status. Bennett argues that one of the key steps in understanding women's role in the determination of child health and nutritional status “may be a careful investigation of the process of resource allocation within the household. “ She opposes the use of a single joint-utility function as an adequate representation of household decision-making dynamics. Her recommendations include conducting investigations from an interdisciplinary approach, including economics, health, nutrition, and anthropology, and she presents a framework for these investigations.

The phloridzin content of dormant terminal twigs of Malus rootstock clones was not related to the vigor imparted to the scions. In young seedling trees it varied with the nutritional status of the plant; an acute deficiency of nitrogen, sulphur, or calcium resulted in a significant increase in phloridzin accumulation. Phloridzin is synthesized readily in the leaf from C14O2 in the light and appears to be stable once formed. Phenylalanine-C14 and tyrosine-C14, when fed to leaf disks, are incorporated into the C6–C3 moiety of phloridzin which includes ring B. Tyrosine is not as effective as phenylalanine. Acetate-C14 is incorporated into ring A. Phloroglucinol is not involved in the synthesis of phloridzin. A method for the quantitative determination of phloridzin is described, also a semimicro method for its alkaline hydrolysis. The large amounts of radioactive D-glucitol formed from a wide variety of precursor compounds indicate a central role for it in the carbohydrate metabolism of Malus.

Determination of nutritional status is closely related to the determination of dietary patterns should be given to infants. Nutrition is very important role in mental, physical development, and human productivity. In this study, the system based on android is developed to determine the nutritional status of infants by using Fuzzy Sugeno. Indicator variables are age, height, circle head, and body weight according to the male or female. In this study, the results of measurements of nutritional status of children with Fuzzy Sugenoare tested by comparing the nutritional quality of the data Posyandu toddler by using anthropometric tables. The results of the evaluation measurement accuracy in this application are compared with the results of manual calculation based infant growth charts according to WHO standards. Therefore, these applications can be used to help the community in monitoring the nutritional status of children so that the growth of children is more appropriate in line with expectations.

Objective: To systematize studies on the anthropometric nutritional status of Brazilian indigenous children in order to examine the ability to address the totality of biological, anthropological, and ecological aspects, as well as to characterize the main analytical results of the determinants of nutritional status of Brazilian indigenous children. Methods: MedLine and Lilacs were searched using the intersection of "South American Indians" and "nutritional status" descriptors (the search in MedLine also included the descriptor "Brazil"). Results: Overall, 65 studies were identified, and 23 were considered relevant to this study. The systematization of these studies highlights the concentration of studies in the midwestern and northern regions of Brazil, as well as the lack of cultural, biochemical, and food consumption approaches. Regarding nutritional status, we found: 1) greater vulnerability of younger children, especially in relation to stunting; 2) absence of differences in nutritional status according to sex; 3) socioeconomic determination of nutritional status; 4) differences in nutritional status between children from different villages. Conclusion: The nutritional status of Brazilian indigenous children is associated with age, socioeconomic status, and ethnic characteristics. Efforts are needed to understand the ethnic and cultural influence on nutritional status and on its causal network, as well as of various factors minimally discussed.

Mangroves are trees inhabiting the intertidal zones of tropical and subtropical coast. They are classified as true mangroves and mangrove associates. In the present study leaf samples of various age groups from five mangrove species and six mangrove associated species were selected for the estimation of chlorophyll content. True mangroves showed comparatively high amount of chlorophyll than mangrove associates and moreover in medium aged leaves chlorophyll contents were more than young and old leaves.

Background: Castilleja tenuiflora is a hemiparasite of Baccharis conferta. The haustorium is the characteristic structure of hemiparasitic plants and its anatomy varies depending several factors such as host species, position on the root and environment.Question: What is the structure and anatomy of haustoria builded in field interaction? Based on C, N and chlorophyll contents, is C. tenuiflora a facultative hemiparasite of B. conferta?Species studied: Castilleja tenuiflora Benth. and Baccharis conferta Kunth.Study site and dates: Plant materials were collected in the Iztaccihuatl-Popocatepetl National Park (N 19° 0.5´ 9.6'', W 98° 40´ 24.2'', 3,480 m.a.s.l.), State of Mexico, Mexico, in December 2013.Methods: Individuals of B. conferta and C. tenuiflora growing independently or in hemiparasite interactions were collected and samples were processed for anatomical and histochemical characterization, determination of C, N and chlorophyll.Results: Haustoria were globular and located mainly in the lateral roots of B. conferta. Anatomy of haustorium shows the characteristic structures: exophyte and endophyte. Haustorial tissues storage starch, tannins and essential oils while in the B. conferta roots also calcium oxalate crystals were found. C levels were significantly influenced by hemiparasitic interaction. This is the first study that characterizes a hemiparasitic interaction in the field and specifically between C. tenuiflora and B. conferta.Conclusions: Haustoria builded in interaction with B. conferta show the characteristic structure and anatomy. Hemiparasitic relationship represents for C. tenuiflora a source of C and other compounds such as essential oils.
