Coffea canephora shows considerable variability for several agronomic traits, including nutritional efficiency. Beside the intrinsic nutritional efficiency of a genotype, the availability of water in the soil is another factor that can cause different responses, which suggests the possibility of selection of genotypes to enhance the nutritional efficiency ... more
Coffee is one of the most valuable agricultural commodities. There is much agronomic research on coffee, but molecular knowledge of its fruit development and ripening is limited. This study reports a comparative proteomic investigation of immature coffee fruits in two early developmental stages: stage 1, cell division and elongation of the perisperm; and stage 2, early growth of the ... more
Biannuality in coffee culture causes temporal variability in plant productivity. Consequently, it is essential to evaluate genotypes during various crop years to ensure selection of productive and stable genotypes. We evaluated the effectiveness of simultaneous selection of coffee genotypes along harvests, based on productivity, stability, and adaptability, via mixed models, for ... more
Coffee quality is directly related to the harvest and post harvest conditions. Non-uniform maturation of coffee fruits, combined with inadequate harvest, negatively affects the final quality of the product. Pectin methylesterase (PME) plays an important role in fruit softening due to the hydrolysis of methylester groups in cell wall pectins. In order to characterize the changes occurring ... more
Cytochrome P450s (P450s) comprise a gene superfamily encoding enzymes that are involved in diverse plant metabolic pathways that produce primary and secondary metabolites such as phenylpropanoids, terpenoids, nitrogen-containing compounds, and plant hormones. They comprise one of the most diverse gene families in plant evolution. Although there are many studies that aim to characterize ... more
The multi-stem aspect of crop systems using Coffea canephora makes it necessary to correctly establish the number of orthotropic stems per plant during the crop formation. ... more
We examined the effect of water availability on the nutritional balance of 15 genotypes of the clonal cultivar “Conilon BRS Ouro Preto” of Coffea canephora grown in two contrasting environments in terms of water availability. Biomass production and nutritional balance parameters, based on the deviance from the standard ratio among nutrients for the species ... more
We conducted a 5 x 5 complete diallel cross experiment in bread wheat (Triticum aestivum) with the genotypes 6309, Chkwal-50, Dhrabi, Bhkhar-02, and FS-08. Our objective was to evaluate the type of gene action and the general and specific combining abilities required for various morphological traits in wheat. The results of analysis of variance revealed highly significant ... more
The aim of this study was to relate flower bud size with microspore developmental stages and the induction of embryos in the anthers of different ornamental pepper (Capsicum annuum L.) genotypes. Flower buds were randomly collected and visually divided into three classes based on both petal and sepal size. The length and diameter of the bud as well as the length of the petal, ... more
Banana is an importment international economical crop, but drought is the most significant environmental stress in banana intrustry. Previous studies on banana drought tolerance evaluated just a few indicators, such as malondialdehyde (MDA) and plasma membrane permeability (PMP), with little or no systematic morphological and physiological information. We examined ... more
