Due to high temperatures, practically all coffee farms in the state of Rondonia are C. canephora species. Thus, importing arabica from other states becomes necessary for composition blends, as well specialty or gourmet market. The purpose this study was select genotypes that exhibit satisfactory agronomic performance under temperature conditions. experiment conducted OuroPreto do Oeste, RO, Brazil, with mean annual 25.8°C and rainfall 2300mm year-1. composed 114 genotypes, 103 progenies...
A divergência genética entre 31 genótipos de melancia foi avaliada por meio da análise variáveis canônicas e técnicas agrupamento (Tocher método hierárquico Ward) baseadas na distância generalizada Mahalanobis (D²ii'). Trinta linhagens, obtidas a partir acessos coletados no Nordeste brasileiro cultivar 'Crimson Sweet' foram avaliadas quanto ao número dias para o aparecimento primeira flor masculina feminina (NDM NDF); do nó (NGM NGF); frutos planta (NFP); comprimento rama principal (CRP);...
ABSTRACT In order to increase the yield of vegetables agronomic interest, heterosis has been studied in view superiority hybrids, if compared genotypes obtained by free pollination. This study aimed estimate relative watermelon regarding most important traits, develop future cultivars. The 'JNY', 'ORA', 'KOD', 'SOL', 'CHG', 'PEA' and all hybrids among them were used, totaling 36 treatments. A randomized block design, with three replications five-plant plots, was used. 'CHG' promising for...
The objective of this work was to characterize 119 accessions guava and 40 "araçá" sampled in 35 Brazilian ecoregions, according the International Union for Protection New Varieties Plants (UPOV) descriptors. majority presented wide spacing leaf veins, while medium close spacing. Most fruits were classified as small, contrasting with large accessions. (91%) white flesh fruit color, 58% pale pink, pink dark colors. Fruit differences among wild cultivated Psidium species indicate most altered...
This paper discusses the petrophysical, mineralogical and P wave velocity characterization of Albian carbonates from Campos basin, Brazil. For experimental characterization, it was used X-ray diffraction (XRD), gas porosimeter permeameter, optical microscopy for thin sections visualization rock physical system determination. Measurements XRD showed that rocks are composed mainly by calcite, but small amounts quartz, dolomite, feldspar fluorite also observed. The section observation revealed...
Allelic patterns and genetic similarity among 17 watermelon cultivars were established using microsatellite markers. For visualization of the similarity, dendrogram UPGMA (Unweighted Pair Group Method with Arithmetic Means) was generated by matrix Jacquard coefficient, based on 34 alleles ten loci. Total DNA extracted CTAB 2x method PCR (Polymerase Chain Reaction) products analyzed in denaturing polyacrylamide 6% gels, stained silver nitrate. The number base pairs estimated inverse mobility,...
