ABSTRACT - The objective of this work was to evaluate the effect of nine rootstocks on 'Jaffa' sweet orange (Citrus sinensis) for its vegetative, productive, and qualitative traits, and for its susceptibility to three pest mites (Eutetranychus banksi, Tetranychus mexicanus and Phyllocoptruta oleivora). The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo Santa Cruz' lime, 'San Diego' citrandarin, and the hybrids HTR-051 and LVK x LCR-010 conferred lower-cumulated yields to 'Jaffa'. The rootstocks did not influence the population levels of the evaluated mites. 'Sunki Tropical' mandarin, 'Cravo Santa Cruz' lime and 'Rugoso Vermelho' lemon stand up as excellent rootstock options for 'Jaffa' sweet orange in the Northeastern Brazil. 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: crescimento vegetativo, produtividade, características fisioquímicas dos frutos e densidade de ácaros-praga. A tangerineira 'Sunki Tropical' conferiu elevada produtividade à laranjeira 'Jaffa', enquanto o tangeleiro 'Orlando' e o limoeiro 'Rugoso Vermelho' induziram frutos maiores, com baixos valores Brix e menos ácidos à laranjeira 'Jaffa'. Os citrandarins 'Indio' e 'Riverside' induziram frutos mais ácidos e de tamanhos menores, assim como baixa produtividade acumulada e menor copa. Adicionalmente, o limoeiro 'Cravo Santa Cruz', o citrandarin 'San Diego' e os híbridos HTR-051 e LVK x LCR-010 conferiram menor produção acumulada à laranjeira 'Jaffa'. Os porta-enxertos não influenciaram os níveis populacionais dos ácaros avaliados. A tangerineira 'Sunki Tropical', o limoeiro 'Cravo Santa Cruz' e o limoeiro 'Rugoso Vermelho' se destacam como excelentes opções de porta-enxertos para a laranjeira 'Jaffa' na região Nordeste do Brasil.

Common bean (Phaseolus vulgaris L.) is a staple food in Brazil with both nutritional and socioeconomic importance. As an orphan crop, it has not received as much research attention as the commodity crops. Crop losses are strongly related to virus diseases transmitted by the whitefly Bemisia tabaci, one of the most important agricultural pests in the world. The main method of managing whitefly-transmitted viruses has been the application of insecticides to reduce vector populations. Compared to chemical vector control, a more sustainable strategy for managing insect-borne viruses is the development of resistant/tolerant cultivars. RNA interference has been applied to develop plant lines resistant to the whitefly in other species, such as tomato, lettuce and tobacco. Still, no whitefly-resistant plant has been made commercially available to date. Common bean is a recalcitrant species to in vitro regeneration; therefore, stable genetic transformation of this plant has been achieved only at low frequencies (<1%) using particle bombardment. In the present work, two transgenic common bean lines were obtained with an intron-hairpin construct to induce post-transcriptional gene silencing against the B. tabaci vATPase (Bt-vATPase) gene, with stable expression of siRNA. Northern blot analysis revealed the presence of bands of expected size for siRNA in leaf samples of the line Bt-22.5, while in the other line (11.5), the amount of siRNA produced was significantly smaller. Bioassays were conducted with both lines, but only the line Bt-22.5 was associated with significant mortality of adult insects (97% when insects were fed on detached leaves and 59% on the whole plant). The expression of the Bt-vATPase gene was 50% lower (p < 0.05) in insects that fed on the transgenic line Bt-22.5, when compared to non-transgenic controls. The transgenic line did not affect the virus transmission ability of the insects. Moreover, no effect was observe on the reproduction of non-target organisms, such as the black aphid Aphis craccivora, the leafminer Liriomyza sp. and the whitefly parasitoid Encarsia formosa. The results presented here serve as a basis for the development of whitefly-tolerant transgenic elite common bean cultivars, with potential to contribute to the management of the whitefly and virus diseases.
