| ABSTRACT This study aimed to evaluate the fertiliser sources and application methods of copper (Cu) in citrus trees during the first years of fruit production. Two experiments were set up in an orchard with 3-year-old sweet orange trees, which were applied with three sources of Cu (nitrate, sulfate or EDTA) either via fertigation (Experiment 1) or via foliar sprays (Experiment 2). Regardless of the fertiliser source, Cu application via fertigation was not efficacious to increase the micronutrient concentration in leaves and, consequently, did not affect fruit yield. Conversely, foliar application of Cu, either as nitrate or sulfate, increased this nutrient level in leaves but when applied as copper nitrate, visual phytotoxicity symptoms were verified in... |

| The purpose of this study was to analyze the spatial variability of soil properties and productivity and the chemical and physical properties of oranges (Monte Parnaso variety) in their geographical quadrants. This experiment was conducted in a commercial orange orchard in the municipality of Nova Laranjeiras in the State of Paraná, Brazil. A GPS receiver and a total station were used to measure the spatial location of the fruit and to determine which quadrant they were located in. In this experiment, 13 trees were studied. Twelve fruits were evaluated in each geographical quadrant, and 156 fruits were considered. After harvest, the productivity was expressed as kg per quadrant (kg quadrant-1). Next, physical tests (equatorial diameter (EqD), total fruit... |

| Brazil was discoverd in 1500 by the Portuguese, two years later the United States be discovered by the Spanish. On April 22th, reaching the South coast of the State of Bahia, they sad the famous phrase: "Terra à vista" (land is Seen). For this reason it is admitted the brazilian citrus industry has also its origin in this State, although the first mention of sweet orange had came in 1540 from the Cananea island by a Spanish author More concerned to the trades with India after the famous discovery of the way in 1498, only 30 years after the discovery, the government of Portugal decided to colonize the country. In order to protect the new colony against posible invasions of french, spanish, deutch and english, which boats were seen frequently sailing along... |

| The citrus plants comprise the genus Citrus and relatives of it, with emphasis to Poncirus, Fortunella, Microcitrus, Eremocitrus and Clymenia. They are among the oldest plants cultivated, a large portion of them native to the Asian continent. The introduction, conservation, characterization, evaluation and documentation of citrus are activities fundamental in dealing with germplasm of this important plant group, contributing as basis to breeding programs and to the diversification of cultivars. |

| Abstract Brazil accounts for a large percentage of the world’s citrus production, with ‘Tahiti’ acid lime tree standing out among several cultivated species. However, its cultivation is supported by a very narrow genetic base, being composed of few scion and rootstock options. In this way, the aim of this study was to evaluate the vegetative development and production of twelve ‘Tahiti’ acid lime clones on two rootstocks. The experiment was carried out at Fazenda José Guarete, municipality of São Mateus – ES. A randomized block design was used in the split plot scheme, with plot consisting of two rootstocks and subplot of the twelve ‘Tahiti’ acid lime clones. Traits evaluated were: vegetative development, production and productive efficiency, internal and... |

| Although the citriculture is one of the most important economic activities in Brazil, it is based on a small number of varieties. This fact has contributed for the vulnerability of the culture regarding the phytosanitary problems. A higher number of varieties/genotypes with potential for commercial growing, either for the industry or fresh market, has been one of the main objectives of citrus breeding programs. The genetic breeding of citrus has improved, in the last decades, due to the possibility of an association between biotechnological tools and classical methods of breeding. The use of molecular markers for early selection of zygotic seedlings from controlled crosses resulted in the possibility of selection of a high number of new combination and, as... |
