Blueberry cultivars of rabbiteye group Bluegem, Briteblue, and Woodard are characterized by having low chilling requirement, high vigor and productivity, being able to be produced in region of Southern Brazil. Studies on cultural practices and field performance in blueberry are recent in Brazil. In order to provide more accurated informations to the growers of this fruit crop, experiments were carried out during 2009 and 2010 in a high potential region. The first experiment was carried out in a didactic orchard at the Federal University of Pelotas (Rio Grande do Sul State), and the objective was to study the field behavior of the blueberries propagated by two different techniques. Evaluations on vegetation, production, and fruit quality aspects were done in order to determine the effect of rejuvenation obtained through micropropagation technique. One year-old plants of blueberry, cultivars Bluegem, Briteblue, and Woodard, obtained from micropropagation and semi-hardwood cuttings were used. It was found that micropropagated plants showed a high initial vegetative growth, and both productivity and fruit quality similar to plants propagated by cuttings. In the second experiment, conducted in a commercial orchard located in the same city of the first experiment...

The peach crop in Brazil is spread from Rio Grande do Sul to Minas Gerais states. It has adapted to different environmental conditions, being cultivated in temperate and sub-tropical zones, since it develops in areas with latitudes between 30?? S and 45?? N. In Rio Grande do Sul, the regions that are outstanding on peach production are: Pelotas; Porto Alegre; and Serra Ga??cha. In the Serra Ga??cha besides peaches for fresh market, are also grown vine grapes and apples. In Porto Alegre, There are peach and plum productions supplying the local market. In Pelotas, most of the peaches produced are for the local industry. However, the canning peaches produced in Pelotas, has worsen the quality and lowered productivity in the last years due to the very variable winter temperature, low chilling hours and severe draught during summer and fall seasons. A way that may contribute for production regularity and to overcome damaging abiotic factors is the right choice of the rootstock. The objectives for this study were: a) to evaluate the agronomical behavior of cultivar Chimarrita on the rootstocks Aldrighi, Capdeboscq, GF305, Okinawa and Tsukuba 1; b) to evaluate the agronomical and phonological behavior of peach trees cultivar Granada on the rootstocks cvs. Aldrighi...

The species of Arecaceae family show great economic importance. They are commercially explored for production of oils, starches, palm heart, waxes and fibers, as well as source of food. Butia capitata produces edible fruits with a good potential in pulp exploration, what can be natural consummated or processed as ice-cream, juice, liqueur and jellies. There has been little research on this specie, facing a large challenge of finding and improving the access with great potential economic. Therefore, this work aimed to evaluate the phenology and characters related to production and furthermore, the physic-chemical and functional attributes of the fruits of the different populations, seeking the best characteristics to commercial exploration. Experiments were carried out in the city of Santa Vit??ria do Palmar. The data used in the first article were taken from two seasons (2005/06 and 2006/07) and from three different populations of butia trees, by using six trees each and 50 fruits from each bunch produced. The second article was divided into two experiments. In the first one it was randomly selected ten butia tree genotypes and assessed characteristics of inflorescence. Therefore, each inflorescence was divided into basal, medium and apical region...

Insufficient chilling accumulation limits the production of peach in subtropical areas. Comparatively this combined with the wide temperature fluctuation during bud differentiation, through the bloom period and fruit growth and development may cause crop losses. Problems with low productivity in southern Rio Grande do Sul often attributed to the mild winter conditions, however, the environmental conditions especially around bloom period to be critical for optimal yields. In subtropical ??reas temperature oscillations may cause problems during fertilization with subsequent reduction of fruit set and production instability of some peach cultivars. To better understand the effect of high temperatures on flower differentiation, pre-blooming, blooming, fruit set and fruit development and growth observations were made during the stages of bud differentiation, leafing and blooming, which included pollen production and viability, floral morphology, fruit set and the fruit growth and development. Temperature elevation with the tree was obtained by bagging branches with transparent plastic or with transparent plastic bottles. Plants of two low chilling peach cultivars (200 to 300 hours): Granada and Maciel were used in the years of 2003, 2004 and 2005. Conditions of high temperatures during the period of bud differentiation of Granada and Maciel did not promote the formation of double pistils or any morphologic anomalies. Bagging shoots with transparent plastic bags and plastic bottles is a simple and economical way of increasing the temperature on the branches under field conditions. High temperatures conditions during pre-blooming period advanced and accelerated the flowers anthesis and pistil growth. Flower morphology...

A major limitation to the expansion of the pear culture cultivated under mild winter, as South of Brazil, is the cultivar adaptation. During the winter, the temperature fluctuation and low accumulation of cold have been reported by some authors as cause of floral button abortion. Moreover, the pear fruit satisfactorily when well managed, being the pruning and girdling one of the main fruiting techniques. This work aimed to evaluate the responses by pear cultivars to different cultural practices in order to increase the fruit an production and to evaluate the development of xylem vessels during dormancy. The work was carried out in two stages: the first in Brazil at the Federal University of Pelotas and the second in Italy, Faculty of Agriculture, in Pisa. In Garber cultivar, the treatments were: 1- control 2- short summer pruning 3- arching of branches and long summer pruning and 4 arching of branches in the winter, 5 - winter pruning; 6 girdling of branches, 7 Promalin ?? and 8 - Biozyme * TF. For the cultivars Shinseiki and Housui, the treatments were: 1 - control, 2 - trunk girdling in April 3 - ringing branches in April. To Kousui, the treatments were: 1 trunk girdling, 2 - branch girdling + pruning 3- pruning, 4- branch girdling 5-control. For the Conference...
