Abstract.
Acca sellowiana, known as 'Guayabo del País' or 'Pineapple guava', is a small evergreen ornamental fruit tree of the family Myrtaceae, native to Uruguay and south-eastern Brazil. It has excellent agronomical and commercial potential, high nutritional value, and is adequate for fresh consumption as well as for the elaboration of manufactured products. Several genotypes with outstanding fruit size and flavor have been selected in the breeding program for this species in Uruguay. However, the low success achieved so far with conventional vegetative propagation of selected materials is an important limitation for commercial production in our country. Micropropagation has been considered as an alternative for the production of high quality, pathogen-free plant material. Rooting of cuttings and microcuttings of woody species is strongly dependent on the genotype of the donor plant and the ability to root is rapidly lost with ageing of the mother plant. The objective of the present study was to evaluate different alternatives to improve rooting ability of selected materials, in vitro. Selected mother plants were cultivated in a greenhouse and used as source of explants for micropropagation. Explants were established in vitro on Woody Plant Medium (WPM) devoid of plant growth regulators, according to a protocol previously developed in our laboratory for this species. Maximum multiplication rate was achieved with 2.85 µM zeatin riboside. We evaluated different rooting alternatives with two selected plant materials, differing in rooting ability. WPM was used as basal medium, supplemented with 10 µM indole-3-butyric acid (IBA), 100 µM sodium nitroprusside (SNP), 1 mM phloroglucinol (PG), or the combination of 10 µM IBA and 1 mM PG. The material that rooted poorly responded to IBA (60% rooting). However, neither PG nor SNP had a positive effect on rooting of microcuttings.

ABSTRACT.- Most of the wood from Eucalyptus globulus Labill. plantations in Uruguay is harvested for pulp industry at an average age of 11 years. In this study we
evaluated the volume and quality of the wood produced and the economic return for owners using different rotation length (from 6 to 13 years) and two different provenances (Jeeralang, Australia and Chivilingo, Chile) in experimental plots planted at two different sites (southwest and southeast of Uruguay). Silvicultural practices, industrial process, and economic aspects of the plantations were evaluated by measuring the following variables: survival, individual and per hectare growth, basic density, cellulose yield, wood consumption, cellulose production per hectare, dry solids content, fiber length, paper resistance, internal rate of return, and soil expectation value. The results showed that an increase in the harvest age generates: (i) an increase in the production of wood and cellulose per hectare at decreasing rates; (ii) an
increase in wood density and yield; (iii) a reduction in the consumption of wood and solid contents in the cooking liquor; and (iv) a reduction in economic profitability at the farm level. No differences were found in the fiber length and resistance properties of the paper from wood harvested at different ages.
