1. Bell pepper rootstocks with multiple resistance to soilborne diseases
ABSTRACT Grafting has been increasingly used to overcome soilborne pathogens. The commercial rootstock hybrids AF-8253 (Sakata) and Fortaleza (Takii), as well as Embrapa’s new hybrid, BRS Acará, were evaluated as rootstocks for the bell pepper hybrids Margarita (Syngenta) and Pampa (Clause) as scions, under natural infestation of Ralstonia pseudosolanacea

3. Selection of genotypes of peach rootstock resistant to Meloidogyne incognita
ABSTRACT The aim of this study was to evaluate the genotypes developed by the Peach Breeding Program at the Federal University of Viçosa, as regards to resistance to M. incognita. Six rootstocks genotypes propagated by cuttings (713-07, 713-13, 913-3, 913-6, 913-11 and 913-17) and two rootstocks propagated by seeds (‘Okinawa’ and hybrid between scion cu

4. Performance of ‘William’s’ pear grafted onto three rootstocks
ABSTRACT Pears are the most imported fruit from Brazil and thus, being an important opportunity to Brazilian growers. However, there are still some problems that restrict pear production, such as the lack of suitable rootstocks. The aim of this study was to assess growth, yield efficiency and fruit quality of ‘William’s’ pear grafted on quinces ‘Cham

5. A Escola Francesa de Geografia
ABSTRACT It was evaluated the possibility to produce two seedlings per avocado seed, through the separation of cotyledons. Two seed lots from two different ungrafted trees were evaluated. From the first tree were obtained 60 seeds, and 50 from the second. Half the seeds of each lot had their cotyledons separated and then whole seeds and half-seeds were sown

6. Avocado: Is it possible to produce two seedlings with one seed?
ABSTRACT It was evaluated the possibility to produce two seedlings per avocado seed, through the separation of cotyledons. Two seed lots from two different ungrafted trees were evaluated. From the first tree were obtained 60 seeds, and 50 from the second. Half the seeds of each lot had their cotyledons separated and then whole seeds and half-seeds were sown

7. Guava seedlings with rootstocks or interstocks and their reaction to salinity
ABSTRACT The introduction of rootstocks for the guava has become necessary due to the advance of guava decline. Among them, Psidium spp. or their hybrids have been evaluated. In addition to disease resistance, tolerance to salinity must be evaluated in the new rootstocks. The aim of this study was to verify the effect of rootstocks and intergrafts on the min

8. Ideal harvesting point of ‘Limeira-IAC382’ trifoliate orange fruits for seed extraction
Resumo O trifoliata é um dos porta-enxertos de maior uso no mundo, principalmente por proporcionar produção de frutos de excelente qualidade. Dentre os fatores que determinam a qualidade fisiológica das sementes está a colheita de frutos na época correta. Objetivou-se com este trabalho monitorar alterações físico-químicas em frutos de trifoliata L

9. Permanent wilt point from two methods for different combinations of citrus rootstock
RESUMO: Considerando que a água é extremamente importante na produção agrícola, mas com restrita disponibilidade em algumas regiões brasileiras, é que esse trabalho buscou identificar o limite hídrico inferior para os porta-enxertos: tangerina Cleóptra (Citrus reshni hort. Ex Tan), limão Volkameriano (Citrus Volkameriano Pasquale), citrandarin ‘I

10. Performance of 'Jaffa' sweet orange on different rootstocks for orchards in the Brazilian Northeast
Resumo: O objetivo deste trabalho foi avaliar o efeito de nove porta-enxertos sobre os parâmetros vegetativos, produtivos e qualitativos da laranjeira-doce 'Jaffa' (Citrus sinensis) e sobre a sua suscetibilidade a três ácaros-praga (Eutetranychus banksi, Tetranychus mexicanus e Phyllocoptruta oleivora). Os seguintes parâmetros foram avaliados: cresciment

11. Peroxidase activity and initial growth of ‘Barbosa’ peach on clonal rootstocks
Resumo Na produção de mudas de pessegueiro é frequente o uso de porta-enxertos de identidade genética desconhecida, obtidos a partir de caroços nas indústrias de conservas. A hipótese testada foi de que existem porta-enxertos que expressam maior compatibilidade, possibilitando maior sobrevivência e melhor crescimento, e que a atividade da peroxidase

12. Rootstock-scion interaction:6. Phenology, chilling and heat requirements of Cabernet Sauvignon grapevine
Resumo A fenologia da videira depende de vários fatores, como genética, características do solo, condições climáticas, pragas e doenças, e práticas culturais do vinhedo. Dentre estas, o porta-enxerto pode ter influência no comportamento da copa. Devido a isso, este experimento foi conduzido por dois anos para determinar o efeito do porta-enxerto na
