1. Influence of Silver Nitrate on Somatic Embryogenesis Induction in Arabica Coffee (Coffea arabica L.)
Abstract The influence of silver nitrate (AgNO3), benzyladenine (BAP), and indole-3-acetic acid (IAA) on low frequency somatic embryogenesis (LFSE) induction in Caturra and Catuaí arabica coffee was evaluated. For the Caturra cultivar, the production of somatic embryos was significantly increased by adding AgNO3 to the semisolid culture medium. The highest

3. Identification of novel and conserved microRNAs in Coffea canephora and Coffea arabica
As microRNAs (miRNAs) are important regulators of many biological processes, a series of small RNAomes from plants have been produced in the last decade. However, miRNA data from several groups of plants are still lacking, including some economically important crops. Here microRNAs from Coffea canephora leaves were profiled and 58 unique sequences belonging

4. Agroforestry systems, nutrients in litter and microbial activity in soils cultivated with coffee at high altitude
Agroforestry systems are an alternative option for sustainable production management. These systems contain trees that absorb nutrients from deeper layers of the soil and leaf litter that help improve the soil quality of the rough terrain in high altitude areas, which are areas extremely susceptible to environmental degradation. The aim of this study was to

5. Simple procedure for nutrient analysis of coffee plant with energy dispersive X-ray fluorescence spectrometry (EDXRF)
Nutrient analysis is used to estimate nutrient content of crop plants to manage fertilizer application for sustained crop production. Direct solid analysis of agricultural and environmental samples by energy dispersive X-ray fluorescence spectrometry (EDXRF) was chosen as alternative technique to evaluate the simultaneous multielemental quantification of the

6. Defense responses to Meloidogyne exigua in resistant coffee cultivar and non-host plant
The resistance of coffee plants to Meloidogyne exigua is conferred by the gene Mex-1. However, the mechanisms of resistance still need to be clarified. Therefore, the penetration, development and reproduction of two populations of M. exigua (M1, isolated from the coffee plant and M2, from rubber tree) in susceptible (Coffea arabica 'Catuai') and resistant (C

7. Vegetative and productive aspects of organically grown coffee cultivars under shaded and unshaded systems
Although Coffea arabica species has its origin in the African understories, there is great resistance on the part of the Brazilian producers for growing this species under agroforestry systems as they fear that shading reduces production. This study aimed at evaluating some vegetative traits and the productivity of organically grown coffee (Coffea arabica L.

8. Pruning cycles and nitrogen fertilization of coffee feilds conducted in the "safra zero" system.
Modern, competitive and cost effective coffee production requires plants with high productivity that are more adapted to mechanical and manual harvesting. ?Safra Zero? is a cultivation system designed to limit plant height and eliminate the need for expensive harvesting during years of low productivity, which usually follow years of high productivity. This s

10. Phosphorus dynamics and availability in soils cultivated with production coffee plants, / DinÃmica e disponibilidade de fÃsforo em solos cultivados com cafeeiro em produÃÃo
During many years coffee (Coffee arabica L.) plants have been considered low responsive to phosphorus fertilization. However, recent research data show that these plants demand high phosphorus quantity to fully develop their vegetative and reproductive systems. Aiming to know how phosphorus availability is influenced by annual P doses and how they may influe

11. Parâmetros fitométricos e produtivos do cafeeiro irrigado e submetido a doses de nitrogênio na Região de Garanhus / Productive parameters of the coffee plant submitted to doses of nitrogen in the area of Garanhus
The coffee practiced in Pernambuco, today, occupies an area of 8 hectares distributed between the Mata Norte (500 ha) and 40 towns of the Wasteland (7.5 thousand hectares). Among the major producing towns stand out Taquaritinga do Norte, Garanhuns, Bom Conselho, Belo Jardim, Brejão and Triunfo. These areas are produced a volume of coffee that correspond onl

12. QUIMIOTERAPIA E TERMOTERAPIA NO CONTROLE DO Colletotrichum gloeosporioides, AGENTE DA MANCHA MANTEIGOSA, EM CAFEEIRO (Coffea arabica L.) / Chemotherapy and thermothetapy to control of Colletotrichum gloeosporioides, agent of blister spot in coffee (Coffea arabica L.)
Seeds play a fundamental role in the dissemination of plant pathogens to long distances and transmission of them to plant. In many crops, fungi can be associated with seeds in all the stages of crop production in addition to surviving longer. For coffee plantation, the transmission by seeds of Colletotrichum gloeosporioides, causal agent of blister spot is a
