A canonical correlation analysis of the association between carcass and ham traits in pigs used to produce dry-cured ham Genet. Mol. Biol.
Ventura,Henrique T.; Lopes,Paulo S.; Peloso,José V.; Guimarães,Simone E.F.; Carneiro,Antonio Policarpo S.; Carneiro,Paulo L.S..
The association between carcass and ham traits in a pig population used to produce dry-cured ham was studied using canonical correlation analysis. The carcass traits examined were hot carcass weight (HCW), backfat thickness (BT) and loin depth (LD), and the ham traits studied were gross ham weight (GHW), trimmed ham weight (THW), ham inner layer fat thickness (HIFT), ham outer layer fat thickness (HOFT), pH (pH) and the Göfo value. Carcass and ham traits are not independent. The canonical correlations (r) between the carcass and ham traits at 130 kg were 0.77, 0.24 and 0.20 for the first, second and third canonical pair, respectively, and were all significant (p < 0.01) by the Wilks test. The corresponding canonical correlations between the three...

Analysis of Input and Output of China's Agriculture Based on Canonical Correlation AgEcon
Chen, Daoping.
I select effective irrigated area, consumption of agricultural chemical fertilizer, electricity consumed in rural areas, and total power of agricultural machinery as input variables of China's agriculture; I select grain, bean, tobacco, oil-bearing crop and fruit as output variables of China's agriculture. By using the data of China Statistical Yearbook in 2010, based on the analysis method of canonical correlation, I conduct research on the input and output of China's agriculture. The results show that consumption of chemical fertilizer has the biggest impact on the agricultural output of China, followed by the input of total power of agricultural machinery; the canonical variable of agricultural output of China is mainly impacted by grain, oil-bearing...

Biometric analysis in maize genotypes suitable for baby corn production in organic farming system Horticultura Brasileira
Nascimento,Maxwel R; Santos,Paulo Ricardo; Coelho,Fábio C; Jaeggi,Mário Euclides PC; Costa,Kleyton Danilo S; Souza,Maurício N.
ABSTRACT The aim of this study was to estimate and quantify the degree of association between phytotechnical variables for simultaneous selection of maize genotypes suitable to produce baby corn. Seven genotypes were arranged in field in randomized complete block design with four replicates. Genetic parameters, simple, path and canonical correlations of phytotechnical variables were estimated. The variables production of marketable spikes, length of marketable spikes, final plant stand and plant height showed over 80% heritability and variation index higher than the unity, indicating that superior genotypes can be obtained and selection gains. Significant phenotypic and genotypic correlations were observed for production of marketable spikes, positive and...

Identification of physiological analysis parameters associated with coffee beverage quality Ciência e Agrotecnologia
Freitas,Marcella Nunes de; Rosa,Sttela Dellyzete Veiga Franco da; Pereira,Cristiane Carvalho; Malta,Marcelo Ribeiro; Dias,Carlos Tadeu dos Santos.
ABSTRACT The demand for high-quality coffee among consumers has generated a great deal of interest among producers in serving this market. Parameters for physiological analyses that can be associated with aspects of sensory analyses of coffee can ensure more reliable results for coffee quality assessments. The aim of this study was to investigate the potential of physiological analyses in determining coffee quality through multivariate analysis. Several samples from coffee bean/seed lots were placed in cold storage at 10 °C, after which the sensory quality, physiological quality, and chemical characteristics of the beans were evaluated before storage and after three and six months of storage. The variables of physiological quality in the coffee beans were...

Linear relations between apple traits Bragantia
Toebe,Marcos; Both,Vanderlei; Thewes,Fabio Rodrigo; Cargnelutti Filho,Alberto; Brackmann,Auri.
ABSTRACT The study of linear associations between traits is critical for the selection or the indirect quantification of the interest traits. Thus, the objective of this research was to evaluate the linear relationships among traits of apple fruits, in ‘Royal Gala’ and ‘Fuji’ cultivars, at harvest and after cold storage. In this investigation, 120 fruits of ‘Royal Gala’ and 120 fruits of ‘Fuji’ at harvest and 120 fruits of ‘Royal Gala’ and 111 fruits of ‘Fuji’ after cold storage were evaluated. Morphological/productive (mass, longitudinal diameter, major and minor transverse diameters) and quality traits (firmness, total soluble solids, titratable acidity, juice content, ethylene production and respiration) were measured. In each cultivar (‘Royal Gala’ and...

Multivariate analysis applied to the study of the relationship between soil and plant properties in a peach orchard Rev. Bras. Ciênc. Solo
Terra,Viviane Santos Silva; Valgas,Ricardo Alexandre; Reisser Júnior,Carlos; Timm,Luis Carlos; Pereira,José Francisco Martins; Carvalho,Flávio Luiz Carpena; Oldoni,Henrique.
In the State of Rio Grande do Sul, the municipality of Pelotas is responsible for 90 % of peach production due to its suitable climate and soil conditions. However, there is the need for new studies that aim at improved fruit quality and increased yield. The aim of this study was to evaluate the relationship that exists between soil physical properties and properties in the peach plant in the years 2010 and 2011 by the technique of multivariate canonical correlation. The experiment was conducted in a peach orchard located in the municipality of Morro Redondo, RS, Brazil, where an experimental grid of 101 plants was established. In a trench dug beside each one of the 101 plants, soil samples were collected to determine silt, clay, and sand contents, soil...

Plant characters of broccoli determinants of head production Ciência Rural
Brandelero,Fernanda Daniela; Brum,Betania; Storck,Lindolfo; Cardoso,Jessica; Kutz,Talita Slota; Vargas,Thiago de Oliveira.
ABSTRACT: The increasing consumption of single-head broccoli is due to several factors, among them there are food production in minimally processing form and the existence of hybrids that adapt to various climates, in addition to the simple harvesting of this typical architecture.This study aimed to identify the most relevant plant characters of broccoli, represented by growth characters, which are determinant in the production and canopy area. The study was conducted in an experimental area in Pato Branco city, PR. The 11 characters were evaluated for 365 plants, spaced with 0.8x0.5m, on a blank experiment. The characters of group 1 (height, number of leaves, stem height, stem diameter) were evaluated on the 21 and 58 day after transplanting (DAT), and...

Segregation of patches by patterns of soil attributes in a native grassland in central Argentina Phyton
Villamil,MB; Amiotti,NM; Peinemann,N.
Demand for greater cattle production at the El Caldenal area in central Argentina has resulted in overgrazing in a patchy grassland structure. Patches are clearly identified on the basis of dominant plant species resulting from their grazing history. Our primary objective was to examine the influence of individual plants at each patch on the local multivariate pattern of soil nutrients, assessing the magnitude of the association between the concentration of nutrients in the plant and its underlying soil. Canonical discriminant analysis highlighted the important role of soil organic matter, available P, and Zn content of soils to segregate among patches. The canonical correlation analysis between soil and plant variables revealed a significant association...

Soil-vegetation relationships and community structure in a "terra-firme"-white-sand vegetation gradient in Viruá National Park, northern Amazon, Brazil Anais da ABC (AABC)
MENDONÇA,BRUNO A.F. DE; FERNANDES FILHO,ELPÍDIO I.; SCHAEFER,CARLOS E.G.R.; MENDONÇA,JÚLIA G.F. DE; VASCONCELOS,BRUNO N.F..
ABSTRACT Viruá National Park encompasses a vast and complex system of hydromorphic sandy soils covered largely by the white sand vegetation ("Campinarana") ecosystem. The purpose of this study was to investigate a vegetation gradient of "terra-firme"-white sand vegetation at the Viruá National Park. Nine plots representing three physiognomic units were installed for floristic and phytosociological surveys as well as to collect composite soil samples. The data were subjected to assessments of floristic diversity and similarity, phytosociological parameters and to statistical analyses, focused on principal components (PC) and canonical correspondence analysis (CCA). The vegetation of the Campinaranas types and Forest differed in biomass and species density....
