Genetic diversity of standard leaf nutrients in Coffea canephora genotypes during phenological phases.
Diagnosing foliar nutritional status is essential for fertilizer recommendations and for the identification of nutrient imbalances. This study aimed to verify genetic diversity and establish mean standards (leaf nutrient contents; LNCs) and relationships among leaf nutrients (LNC relationships; LNCRs) in seven conilon coffee genotypes during both pre-flowering and bean-filling stages. Twenty cr...
متن کاملAllometric model for estimating leaf area in clonal varieties of coffee (Coffea canephora)1 Modelo alométrico para estimativa da área foliar de variedades clonais de café (Coffea canephora)
The evaluation of leaf area is required in several agronomic studies given their importance to assess the plant growth. The objective of this study was to use statistical models to estimate leaf area of five clonal varieties of coffee (Coffea canephora) from linear dimensions (length and width maximum). Were used in the studies five varieties of Coffea canephora Pierre ex Froehner: Emcapa 8111,...
متن کاملIsolation and characterization of cDNA encoding three dehydrins expressed during Coffea canephora (Robusta) grain development.
BACKGROUND AND AIMS Dehydrins, or group 2 late embryogenic abundant proteins (LEA), are hydrophilic Gly-rich proteins that are induced in vegetative tissues in response to dehydration, elevated salt, and low temperature, in addition to being expressed during the late stages of seed maturation. With the aim of characterizing and studying genes involved in osmotic stress tolerance in coffee, seve...
متن کاملSNPs Based Molecular Diversity of Coffea canephora
Coffee offers one of the most widely drunk beverages in the world, and is a very important source of foreign currency income for many countries. Coffea canephora Pierre presents a great genetic variability, with one of the widest natural geographical distribution within the subgenus. Newly developed single nucleotide Polymorphism (SNP) markers are effective in genetic diversity detection. The o...
متن کاملBiosynthesis of chlorogenic acids in growing and ripening fruits of Coffea arabica and Coffea canephora plants.
Chlorogenic acids are major secondary metabolites found in coffee seeds. The accumulation of chlorogenic acids and free quinic acids was studied in Coffea arabica cv. Tall Mokka and Coffea canephora seeds. Growth stages are specified from I to V, corresponding to rapid expansion and pericarp growth (I), endosperm formation (II), mature (green) (III), ripening (pink) (IV), and fully ripened (red...
