Different procedures for the integrated method of diagnosis and recommendation may influence the accuracy of foliar diagnosis of mango. Thus, the objective of this study was to compare the diagnosis of nutritional status of mango obtained by different methods of assessing nutritional status, comparing multivariate relations (method CND) with bivariate relationships (DRIS) i.e., variations in the use of specific or preliminary standards and a logarithmic transformation of the data. The macro and micronutrient leaf analysis results of 63 mango orchards of Lower-middle São Francisco River Valley, Brazil, were used. To interpret nutritional status the Potential Response to Fertilization (PRA) criteria was used. The CND and DRIS methods, with and without logarithmic transformation and using specific or preliminary standards, which showed similar performance in assessing the nutritional status of the mango in Lower-middle San Francisco. Mango orchards in the semiarid region of northeast Brazil, the micronutrient deficiencies (Zn, Fe and Cu) were more frequent than macronutrient deficiency.

We report the discovery of 13 synonymous single nucleotide polymorphisms (SNPs) within a fragment of HSC70 gene in Macrobrachium amazonicum. Polymorphisms were assessed using the reference sequence of the HSC70 gene in Macrobrachium rosenbergii to the primers design. The minor allele frequency ranged from 0.011 to 0.213. None of the SNPs deviated significantly from Hardy-Weinberg equilibrium. These SNPs will be useful to access the genetic variation of populations and to the study of their relations with characteristics of interest for aquaculture. Both cases, favoring the conservation of the natural stocks of Amazon river prawn. © 2013 Springer Science+Business Media Dordrecht.
