2. Resistance and susceptibility of mandarins and their hybrids to Alternaria alternata
Caused by Alternaria alternata, Alternaria brown spot (ABS) is a major fungal disease of mandarins in Brazil, causing serious losses in commercial orchards of Ponkan tangerine (Citrus reticulata Blanco) and Murcott tangor [C. sinensis (L.) Osbeck × C. reticulata Blanco]. The response of 31 accessions/genotypes of mandarins and their hybrids to A. alternata,

3. Tentativas de purificação e produção de antissoro contra o vírus da morte súbita dos citros e isolamento do CSDaV em plantas herbáceas / Attempts to purify and produce antiserum against the citrus sudden death associated virus and CSDaV isolation in herbaceous plants
Citrus sudden death (CSD) disease was identified in 2001, at Comendador Comes County, State of Minas Gerais, Brazil. Since then the disease has caused the death of 4 million trees in Southwestern Minas Gerais State and Northern São Paulo State. This new and destructive disease affects sweet orange as well as other species, varieties, and hybrids when grafte

4. Comparative analysis for quantification of Citrus Variegated Chlorosis in the field
Citrus Variegated Chlorosis (CVC) caused by Xylella fastidiosa is one of the most important diseases for Brazilian citriculture. The CVC is a vascular disease with a long incubation period and symptoms similar to other disorders, and this factors difficult the CVC quantification in the field. Two methods of CVC assessment were compared in this study. The fir

5. Use of horticultural practices in citriculture to survive Huanglongbing.
Citriculture is one of the major activities of the Brazilian agribusiness found throughout the entire country in different production environments. The presence of the Huanglongbing (HLB), reported in Brazil in 2004, has led to severe losses in important producing regions, challenging the sustainability of the citrus chain. Current control strategies are bas

6. Influencia do pH e do agar sobre o cultivo in vitro de embrioes de laranjeira pera.
Objetivou-se com o presente trabalho determinar a interacao do pH e do agar no cultivo in vitro de embrioes da laranjeira Pera (Citrus sinensis Osb.). Os tratamentos consistiram das concentracoes de 0,0; 3,5; 7,0; 10,5 e 14,0 g/L de agar associadas as afericoes de pH do meio de cultura MS em 3,7; 4,7; 5,7 e 6,7, antes da esterilizacao em autoclave. Maiores c

7. Análise comparativa da predação de Toxoptera citricidus (Kirkaldy) e Aphis spiraecola (Patch) (Hemiptera: Aphididae) por artrópodes, em cultura de citros, através da serologia
Citriculture is one of the most important agricultural activities in Brazil, and its production, specially directed to the export of concentrated juice, generates profits that surpass one billion dollars a year. In the present work, specific antisera for Aphis spiraecola (Patch) and Toxoptera citricidus (Kirkaldy) (Hemiptera: Aphididae) were produced, and po

8. Porta-enxertos utilizados na citricultura / Citriculture rootstocks in use
A muda cítrica é o insumo mais importante na formação de um pomar. As características mais importantes da muda cítrica são a origem do enxerto e do porta-enxerto, a qualidade do sistema radicular e a sua sanidade. Os portaenxertos são capazes de influenciar várias características horticulturais e sanitárias nas árvores e nos frutos cítricos, com

9. Medições do saldo de radiação em copas de cafeeiros e limeiras ácidas por sistemas de integração espaço-temporal e estimativas por técnicas de modelagem / Measurements of net radiation of the canopy of coffee and acid lime trees in hedgerows by spatiotemporal integration systems and estimates by modelling techniques
The amount of radiant energy absorbed by the canopy of trees has great application in photosynthesis and transpiration research. Studies of radiation interception by the canopies of an isolated or a sequence of trees in hedgerows have been carried out by a technique which employs moving radiometers around an isolated tree (spherical geometry of measurement)

10. Avaliação da interação entre Methylobacterium spp. e citros / Evaluation of the interaction between Methylobacterium spp. and citrus
A interação bactéria-planta é um processo complexo que envolve diversos fatores bióticos e abióticos, podendo resultar em interações neutras, benéficas ou patogênicas. O gênero Methylobacterium tem sido descrito como endófito em diferentes plantas hospedeiras, podendo beneficiá-las por meio da promoção de crescimento vegetal e do controle de f

11. Modelling evapotranspiration for reference crop and acid lime orchard based on regression and artificial neural network tecniques / Modelagem da evapotranspiração de referência e da evapotranspiração de limeira ácida com aplicação de técnicas de regressão e redes neurais artificiais
The main objective of this study was to test artificial neural networks (ANNs) of multilayer perceptron type (MLP) for estimating reference evapotranspiration, diffusive leaf conductance and crop evapotranspiration of a mature and irrigated citrus orchard. The ANNs were trained under conjugate gradient algorithm. The sigmoid and linear activation functions w

12. Construção de cDNA infeccioso de Citrus Sudden death-associated virus
The orange is an important fruit, widely spread around the world and very well suited to the climate in Brazil. However, citriculture has suffered a lot with a new disease, called Morte Súbita dos Citros (MSC) (Citros Sudden Death Disease) that has been recognized the first time in 2001 in Minas Gerais State, Brazil. The disease cause severe damages to plan
