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.
The objective of this study was to evaluate the effect of nutritional management during rearing and finishing phases on beef fatty acid composition, and carcass and beef quality traits of Hereford cattle. The study used 240 castrated male calves weaned at 8 months of age, and with an average weight of 170 ± 17 kg. After weaning, the experiment was divided in to three phases in a 4 × 2 factorial design: a 93-day winter period with four treatment groups (on pasture or in feedlot and at high or low feeding levels); a 196-day compensatory-growth phase on pasture; and a finishing phase either on pasture or in feedlot. Animals were slaughtered when each group attained a mean liveweight of 500 kg. The winter growth × finishing management interaction significantly affected hot carcass weight (P = 0.0029). There was no differences observed for feedlot-finished steers, but for pasture-finished steers, those pasture-reared had higher hot carcass weight (kg) than those feedlot-reared (low pasture 256.30 ± 1.60, high pasture 253.72 ± 1.60, low feedlot 249.85 ± 1.66, high feedlot 247.60 ± 1.62). Feedlot-finished steers showed higher (P < 0.05) mean values than pasture-finished steers for ribeye area (55.61 ± 0.69 cm2 vs 53.18 cm2), backfat thickness (8.62 ± 0.32 mm vs 6.21 mm), marbling score (237.97 ± 13.06 vs 171.70) and final pH (5.53 ± 0.02 vs 5.48). Additionally, feedlot-finished steers raised in feedlot during the winter-growth period displayed the heaviest hindquarter cuts. Meat from pasture-finished steers had lower (P < 0.05) shear-force values than from feedlot-finished cattle (2.95 ± 0.18 vs 3.66 ± 0.17 kg), and when reared on either high or low pasture during winter-growth, they showed the highest (P < 0.05) conjugated linoleic acid (cis-9, trans-11) and n-3 polyunsaturated fatty acid concentrations. In conclusion, growing and finishing cattle on pasture improved the carcass yield of retail cuts because of low fat concentration, and improved the nutritional and health value of the beef fatty acid profile.
