Resumo: | The world food production and the crop production has been affected by pests, insects, fungous, bacteria, viruses and nematodes and also by abiotic factors as water availability, soil salinity among others that affect several crops. The guava crop has important role in the economy, particularly in the family farming in Northeast Brazil especially in the irrigated crops of the Semiarid region. In this crop, Meloidogyne enterolobii, a gall nematode together with the Fusarium solani, cause a complex disease that make unviable several production areas. Besides these problems, the irrigated areas are prone to soil salinity that can also affect the crop. Thus, the search for genotypes in the genus Psidium to be used as resistant rootstock to these stresses or to be used in breeding programs that are devoted to obtain clones that allow the commercial production of guava in the country. Therefore, the aim of this work was to evaluate the reaction of Psidium spp. accessions to different doses of inoculum and also to evaluate the effect of osmoconditioning of Psidium guineense to saline stress. The first trial was carried out in a completely randomized bloc with eight replications. The accessions were inoculated with three inoculum densities (600, 1600 and 2000 eggs/mL) and they were evaluated 135 days after inoculation. The second trial was carried out in a completely randomized block with 25 seeds per replication, using osmoconditionated and not osmoconditionated seeds. It was found genetic variability among and within the accessions to reaction to M. enterolobii. Different inoculum densities can affect, in a differential way, the reproduction rate of the nematode in the root system of each plant and, thus, to make it difficult to identify the reaction of plants to the nematode M. enterolobii. Different electric conductivities affected the seeds regarding all variables evaluated in osmoconditionated and non condicionated seeds. The osmoconditioning can decrease the average and speed of seed germination of P. guineense in conditions of medium salinity level. |

Disserta??o (Mestrado Acad?mico em Recursos Gen?ticos Vegetais) - Universidade Estadual de Feira de Santana, Feira de Santana, 2017.http://localhost:8080/tede/handle/tede/572The world food production and the crop production has been affected by pests, insects, fungous, bacteria, viruses and nematodes and also by abiotic factors as water availability, soil salinity among others that affect several crops.

The osmoconditioning can decrease the average and speed of seed germination of P. guineense in conditions of medium salinity level.A produ??o mundial de alimentos e a produtividade agr?cola t?m sido bastante afetadas por agentes bi?ticos como pragas, insetos, fungos, bact?rias, v?rus e nematoides e tamb?m por fatores abi?ticos como a baixa disponibilidade h?drica, salinidade dos solos dentre outros afetando diversas culturas. A cultura da goiabeira tem importante papel na economia, com destaque para a agricultura familiar no Nordeste brasileiro, especialmente os cultivos irrigados do Semi?rido. Nessa cultura, Meloidogyne enterolobii, o nematoide-das-galhas da goiabeira, juntamente com Fusarium solani, causam doen?a complexa que tem inviabilizado muitas ?reas de produ??o. Al?m desses problemas, as ?reas irrigadas do Semi?rido s?o sujeitas a problemas de salinidade dos solos e que podem atingir tamb?m a cultura da goiabeira. Em vista disso, a busca, dentro do g?nero Psidium, por gen?tipos para uso direto como porta-enxertos resistentes a esses estresses ou para subsidiar programas de melhoramento gen?tico com vistas ? obten??o de clones que viabilizem a produ??o comercial da goiabeira, tornou-se a linha mais atual de alguns programas de pesquisa no Brasil. Assim o presente trabalho teve como objetivo avaliar a rea??o de acessos de Psidium spp. a diferentes densidades de in?culo e avaliar o efeito do osmocondicionamento de sementes de Psidium guineense submetidas ao estresse salino. O primeiro experimento foi realizado em delineamento inteiramente casualizado com oito repeti??es, onde os acessos foram inoculados com tr?s densidades de in?culo 600, 1600 e 2000 ovos/mL e avaliados 135 dias ap?s inocula??o. O segundo experimento foi em delineamento inteiramente casualizado com 25 sementes por repeti??es utilizando sementes osmocondicionadas e n?o osmocondicionadas. Existe variabilidade entre e dentro dos acessos avaliados para rea??o a M. enterolobii. Diferentes densidades de in?culo podem afetar de modo diferenciado, a taxa de reprodu??o do nematoide no sistema radicular de cada planta e, assim, dificultar a identifica??o da rea??o das plantas ao nematoide. M. enterolobii. Diferentes condutividades el?tricas afetaram todas as vari?veis avaliadas em sementes osmocondicionadas e n?o osmocondicionadas. O osmocondicionamento pode diminuir o tempo m?dio e velocidade m?dia de germina??o de sementes de Psidium guineense em condi??es de mediana salinidade.Submitted by Jadson Francisco de Jesus SILVA (jadson@uefs.br) on 2018-01-26T22:52:48Z No. of bitstreams: 1 Disserta??o Final_Patricia Gomes de Oliveira.pdf: 1649219 bytes, checksum: bbddc913ad0687cec74a62d0e8eb2b79 (MD5)Made available in DSpace on 2018-01-26T22:52:48Z (GMT).
