ABSTRACT.
The potato crop (Solanum tuberosum L.) is of great importance in the Uruguay economy, being the major vegetable in volume of trade. Uruguay imports some amount of potato seed annually. The National Institute of Agricultural Research (INIA) has been engaged for the last decades to obtain cultivars more adapted to country agroecological conditions, easier to multiply locally for replacing imported seed cultivars such as 'Chieftain'. In this sense, promising cultivars including 'INIA-Iporá' were developed. The objective of this work was to study the morpho-physiological and yield modifications of two potato cultivars ('Chieftain' and 'INIA-Iporá') under different irrigation managements. The experiment was carried out during 2006 and 2007 growing seasons under a rainout shelter, at the Experimental Station INIA Las Brujas, in Uruguay. These two varieties were studied under two irrigation managements: (i) irrigated treatment (2003/04 rainfall + irrigation according to daily crop ETc) and; (ii) deficit irrigated treatment (2003/04 rainfall + one irrigation of 25 mm when the accumulated maximum daily crop evapotranspiration reached 90 mm). The maximum daily crop evapotranspiration was estimated using the FAO Penman-Monteith equation. The experimental design was a completely randomized split plot. The leaf area index, the total plant photosynthesis and the crop yield better responded to the irrigation regime. The two potato cultivars showed differences in length of growing season, leaf area, number of mainstems, plant height and plant transpiration rates. The yield components were modified by the irrigation managements, and differences in commercial yield and total number of plant tubers were observed between the 'Chieftain' and 'INIA-Iporá' cultivars.

ABSTRACT.- Diversification of rootstock varieties, with consequent reduction in phytosanitary risks, has great importance to the sustainability of citrus cultivation in the south of Brazil. This study evaluated the performance of 42 rootstocks in the nursery phase to generate ?Valencia Late? sweet orange seedlings. Therefore, nucellar seedlings from the rootstocks under study were analyzed in relation to plant height, stem diameter, mortality rate and percentage of bud set after grafting. The experimental design was completely randomized with four replications of 20 sample units. Not adapted genotypes had high mortality rates, and the ones of both hybrids LCR x CTSW - 009 and LVK x LCR - 038 were 100% and 90%, respectively. Other 13 genotypes had mortality rates above 30%, and ?Sunki? mandarin was the female genitor of ten of them. ?Swingle? citrumelo was the rootstock with the highest development (plant height and stem diameter), associated with low mortality rate. In relation to the other rootstocks, the best results were the fast grafting diameter, associated with low mortality rate obtained by hybrids HTR - 053, LRF x (LCR x TR) - 005, CLEO x TRBN - 245, CLEO x TRSW - 287, and citrandarins ?Indio?, ?Riverside? and ?San Diego?, as well as Trifoliate orange and ?Rangpur? lime. In addition to Trifoliate orange, which is widely used in Rio Grande do Sul, these rootstocks have great potential in citriculture in the south of Brazil.

RESUMO.- A diversificação do uso de variedades porta-enxerto, com a consequente redução de riscos fitossanitários, é de fundamental importância para a sustentabilidade da citricultura do Sul do Brasil. O objetivo deste trabalho foi avaliar o comportamento de 42 porta-enxertos na formação de mudas de laranjeira ?Valência Late? em fase de viveiro. Nesse sentido, seedlings (plantas oriundas da germinação de sementes) nucelares dos porta-enxertos estudados foram avaliados relativamente aos caracteres altura da planta, diâmetro do caule, taxa de mortalidade e percentagem de pegamento de borbulhas após a enxertia. O delineamento experimental foi inteiramente casualizado, com quatro repetições de 20 unidades amostrais. Genótipos não adaptados tiveram altas taxas de mortalidade, os híbridos LCR x CTSW - 009 e LVK x LCR - 038 apresentaram 100% e 90% de mortalidade, respectivamente. Mais 13 genótipos apresentaram mortalidade superior a 30%, destes, dez têm como parental feminino a tangerineira ?Sunki?. O citrumelo ?Swingle? foi o porta-enxerto que apresentou maior desenvolvimento (altura da planta e diâmetro do caule), associado a uma baixa taxa de mortalidade. Quanto aos demais porta-enxertos, destacaram-se por atingir rapidamente o diâmetro de enxertia, associado a baixa taxa de mortalidade, os híbridos HTR - 053, LRF x (LCR x TR) - 005, CLEO x TRBN - 245, CLEO x TRSW - 287, citrandarins ?Indio?, ?Riverside? e ?San Diego?, assim como o limoeiro ?Cravo? e o Trifoliata. Além do Trifoliata, amplamente utilizado no Rio Grande do Sul, estes porta-enxertos são promissores para a citricultura do Sul do Brasil.
