Nowadays, there is a great interest in using lignocellulosic materials as substrate for the production of
biorefi nery products. Eucalypti are good options to use as crops to obtain different kinds of biofuels and
derivatives, since their plantations show high adaptation potential to soil and weather conditions in Uruguay.
The basic process steps involved in the obtainment of biorefi nery materials are: pretreatment, hydrolysis,
fermentation and products separation. As delignifi cation is an important process to obtain biorefi nery products,
in this context the evaluation of the biological (BT) and hydrothermal (TT) pretreatment of different species of
Eucaliptus was studied. The possibility of obtaining sugars, alcohols and organic acids was the main focus.
The results of these investigations show a good production of reducing sugars (4?5 mg/mL for both BT and
TT pretreatments), acetic acid (3?8 mg/mL for BT and 3?7 mg/mL for TT) and isopropanol (18?48 mg/mL for
BT and 20?30 mg/mL for TT). In conclusion, the results show similar behaviours for BT and TT pretreatments,
which is a quite important result since BT is cheaper and cleaner and thus a more attractive technology. |

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.
