14. The structural studies on the medicinal plant Haplophyllum telephioides
ABSTRACT Haplophyllum telephioides Boiss., Rutaceae, is an endemic herb which generally grows at the steppe region in Central Turkey. Its aerial parts in flowering stage are used by local people against influenza virus due to its antimicrobial effect. The main purpose of this study was to examine the morphology, anatomy and histology of the vegetative and re

15. Nitrogen and Potassium Fertilization in a Guava Orchard Evaluated for Five Cycles: Effects on the Plant and on Production
ABSTRACT Guava response to fertilization can be monitored through plant tissue analysis. Correct interpretation of these results, based on standard levels, is of great importance for correct nutrient management of the crop. However, standard levels are constantly criticized for not considering interactions among elements. To improve the nutritional diagnosis

16. Corn Yield and Foliar Diagnosis Affected by Nitrogen Fertilization and Inoculation with Azospirillum brasilense
ABSTRACT The biological nitrogen fixation (BNF) process in grasses is caused by diazotrophic bacteria, particularly Azospirillum brasilense. However, studies are lacking on BNF efficiency to define how much mineral nitrogen (N) can be applied to achieve more sustainable high yields. Furthermore, there should be an analysis of whether urea with the urease enz

17. Diagnostic Methods to Assess the Nutritional Status of the Carrot Crop
ABSTRACT Leaf analysis may identify nutrient deficiency or excess in plant tissue. The aim of this study was to determine reference values and generate nutritional diagnosis from the results of leaf analysis of the carrot crop (Daucus carota L.) by the methods of Critical Level, Sufficiency Range, Diagnosis and Recommendation Integrated System, and Compositi

18. The relation between dermoscopy and histopathology of basal cell carcinoma
Abstract BACKGROUND: Basal cell carcinoma is the most frequent cancer in fair-skinned populations and dermoscopy is an important, non-invasive technique that aids in the diagnosis of Basal cell carcinoma. OBJECTIVES: The aim of this study was to evaluate the relationship between histopathological subtypes and dermoscopic features of Basal cell carcinoma. MET

19. Comparative leaf anatomy and morphology of some Brazilian species of Crotalaria L. (Leguminosae: Papilionoideae: Crotalarieae)
Anatomical characters often provide strong taxonomic evidence and many times help define species whose morphological limits are in question. This study aimed to survey characters of the leaf anatomy of 16 species of Crotalaria L. occurring mostly in the cerrado (savanna) of central Brazil and in areas of restinga (coastal woodland, or sandy forest) along the

20. Polyclonal antibodies to the putative coat protein of Citrus leprosis virus C expressed in Escherichia coli: production and use in immunodiagnosis
This work reports the in vitro expression of Citrus leprosis virus C (CiLV-C) putative coat protein (p29) and the production of a polyclonal antibody to be used as a tool for serological diagnosis of citrus leprosis. The ORF2/RNA1, corresponding to p29, was cloned in pET28a and transformed into Escherichia coli cells (BL21). Expression of p29 was induced in

21. ÍNDICE RELATIVO DE CLOROFILA PARA O DIAGNÓSTICO DO ESTADO DE NITROGÊNIO EM HÍBRIDOS DE MILHO
Nitrogen (N) is the nutrient that contributes the most to increase productivity of corn hybrids. For this reason, the main objective of this study is to determine the relative chlorophyll index (RCI), in different leaves and phenological stages, aiming diagnosing N state in corn hybrids according to the N doses applied in coverage, correlating them with the

22. Otimização da detecção de raquitismo da soqueira e escaldadura das folhas em cana-de-açúcar utilizando PCR / Optimization of detection of Ratoon Stunting Disease and Leaf Scald Disease in sugarcane by PCR
O cultivo de cana-de-açúcar está em expansão no Brasil, devido ao crescente consumo de etanol por carros bicombustíveis. A área plantada está em crescimento, mas a produtividade nos últimos anos vem decrescendo, e fatores como incidência de doenças podem estar contribuindo para tal situação. Dentre as doenças, as bacterianas, como o Raquitismo d

24. Variabilidade espacial e temporal das propriedades quÃmicas do solo e das folhas, qualidade do fruto e produtividade em pomar de laranja Monte Parnaso
The plant nutritional quality influences directly in juice quality. Therefore it is important the knowledge of its spatial and temporary variation in the orchard for a better application and use of the inputs, larger yield and quality of fruit. This way, input maps can be generated for the best use, providing larger yield and better quality of fruits, reduct
