ABSTRACT.
The apple production area in Uruguay is of approximately 4000 ha, with an average fruit production of 62,000 t per year. Apple is the most important crop within deciduous fruits, and has behaved as the most demanding, in crop technology, during the last years. Local climate and soil conditions in the south of the country, where the major apple producing area is located, can generate sanitary problems to apple trees. New rootstocks of CG series were introduced from Cornell University in 1996 by the Fruit Program of the National Agricultural Research Institute (INIA - Uruguay) with the purpose of evaluating new tools to solve some of these soil problems as Eriosoma lanigerum and Phytophthora sp. The rootstocks introduced were CG 16, CG 3041 and CG 5935. CG41 was selected through the results of the first trials since this rootstock showed to be well adapted, very precocious and productive, with similar vigor to M9, tolerant to Eriosoma lanigerum, and resistant to Phytophthora sp. This work was carried out to develop a protocol of in vitro propagation of CG41 rootstock, in order to generate faster plant availability to nurseries. Cytokinin (benzyladenine and thidiazuron) effect was evaluated during the multiplication phase. The multiplication rate obtained was higher than three and there was significant difference between the treatments compared. Thidiazuron was the most effective hormone in the phase of multiplication. However, thidiazuron used in successive sub-cultures generated deformations in explants and leaves of plantlets. Therefore its incorporation had to be alternated with other growth regulators. Also different elongation media were compared and the most effective included kinetin's addition. Finally, different rooting substrates were evaluated. At this level the cut in V at the base of the plant was critical, independently of its size. MenosABSTRACT.

Abstract:
The land cover change of Uruguayan Forestal Plan provoked biogeochemical changes on horizon Au1 of Argiudols; in native prairies which were replaced by monoculture Eucalyptus sp. plantation with 20 year rotations as trees. Five fields forested and six natural prairies were compared. The results not only show a statistical significant soil acidification, diminution of soil organic carbon, increase of aliphaticity degree of humic substances, and increase of affinity and capacity of hydrolytic activity from soil microbial communities for forested sites with Eucalyptus sp. but also, a tendency of podzolization and/or mineralization by this
kind of land cover changes, with a net soil organic lost of 16.6 tons ha1 in the horizon Au1 of soil under Eucalyptus sp. plantation compared with prairie. Besides, these results point out the necessity of correction of the methodology used by assigned Uruguayan commission to assess the national net emission of greenhouse gases, since the mineralization and/or podzolization process detected in forested soil imply a overestimation of soil organic carbon. The biochemical parameters show a statistical significant correlation between the soil organic carbon status and these parameters which were presented as essential for the correct evaluation of Uruguayan soil carbon sink. |
