1. Viróides em citros no Estado do Rio de Janeiro
RESUMO Os viróides infectam plantas de grande importância econômica como os citros. Objetivando detectar a presença de viróides através de métodos moleculares em árvores cítricas, cinco propriedades em Araruama, no Estado do Rio de Janeiro foram avaliadas. Vinte e duas amostras foram coletadas a partir de plantas com nanismo, rachadura no tronco e e

2. Dwarfing-canopy and rootstock cultivars for fruit trees
Resumo Como as plantas frutíferas apresentam em geral porte elevado, a obtenção de plantas de porte reduzido, ou até anãs, é de grande interesse na fruticultura. Nesta revisão são comentadas algumas das principais plantas frutíferas de clima tropical, subtropical ou temperado que têm variedades de porte reduzido, ou mesmo anãs. As causas do nanis

3. Performance of new apple rootstocks for Gala variety in Southern Brazil
Abstract The objective of this study was to evaluate the performance of Geneva(r) apple rootstocks for 'Gala'. The experiment was set in a complete randomized block design with four replications of tree plants per plot. It was used ten Geneva(r) rootstocks and M.9EMLA and M.7EMLA as controls. It was evaluated plant vigor, annual yield, cumulative yield, cumu

4. Genetic analysis of reciprocal differences in the inheritance of in vitro characters in pearl millet
Abstract Reciprocal differences persist in nature because of the unequal contribution of cytoplasmic determinants from male and female gametes to the zygote. The inheritance of genetic differences is an important factor that influences various traits, including somatic embryogenesis and regeneration in vitro. In this report, we estimate the cytoplasmic and m

5. Identification and characterization of viroids in 'Navelina ISA 315' sweet orange
To date, seven species of viroids have been described infecting Citrus. However, only Citrus exocortis viroid (CEVd), Hop stunt viroid (HSVd) and Citrus dwarfing viroid (CDVd) have been reported in this crop in Brazil. The aim of our work was to identify and characterize viroids infecting plants of 'Navelina ISA 315' sweet orange cultivar grafted on 'Rangpur

6. Passifloras silvestres: área foliar, relações alométricas e potencial como porta-enxerto do maracujazeiro-amarelo / Wild passifloras: leaf area, allometric relationships and potential as a rootstock of yellow passion
The objectives of this work were to develop linear models that allow to predict leaf area of P. alata, P. coccinea, P. gibertii, P. ligularis, P. misera, P. mucronata, P. nitida and P. setacea by using simple linear measurements; to quantify growth traits and allometric relationships of P. cincinnata, P. edulis f. flavicarpa, P. gibertii, P. morifolia and P.

8. Influence of plant height and of leaf number on maize production at high plant densities.
This experiment was conducted in Ames, Iowa, US, with the purpose of verifying if reduction in plant height, through the use of dwarfing genes, or leaf number, by growing short season genotypes, can be a useful strategy to reduce barrenness and improve maize tolerance to drought and high plant population stresses. Five genotypes were tested: a full season hy

9. Espécies de viróides associadas a caneluras nos ramos em limeira ácida 'Tahiti' no Estado de São Paulo, Brasil
Os viroides têm sido empregados em diversos países como agentes indutores de nanismo transmissíveis por enxertia ("graft transmissible dwarfing agents", GTDA), principalmente visando à diminuição do porte das plantas, o que permite o adensamento do pomar. No Estado de São Paulo, Brasil, plantas de limeira ácida 'Tahiti' são normalmente enxertadas co

10. Viroides em citros
Os viroides são os menores fitopatógenos conhecidos. Constituídos por uma molécula de RNA de fita simples, circular, que não é encapsidada e não codifica proteínas, são capazes de se replicar de maneira autônoma nas células do hospedeiro. Os viroides de citros pertencem à família Pospiviroidae (cujos membros apresentam uma região central conser

11. Seleção de genótipos de soja resistentes a duas estirpes de Soybean mosaic virus
Soybean mosaic virus (SMV) is the most prevalent virus on soybeans (Glycine max) throughout the world. It causes mottling on seeds and has been associated with yield reduction. Recently, a new strain (SMV 95-1) was found infecting resistant cultivars, causing dwarfing and systemic necrosis. In a screening test carried out with the strains SMV 95-1 and SMV 95

12. The Influence of Dwarfing Interstocks on the Distribution and Metabolism of Xylem-Applied [3H]Gibberellin A4 in Apple
The influence of an interstock of the dwarfing cultivar M9 and the nondwarfing cultivar MM115 on the distribution and metabolism of labeled gibberellic acid A4 ([3H]GA4) of high specific radioactivity (5.18 × 1010 becquerel per millimole) applied to the xylem of the rootstock in grafted apple (Malus × domestica Borkh.) trees was compared.
