Influence of organic and mineral fertilization on sugar contentin Italian Riesling grape varietyBlidariu C. 1 , Sala F. 1 *Banat’s University of Agricultural Sciences and Veterinary Medicine, Timişoara, Romania – Faculty ofAgriculture - Agro chemistry and plant nutrition compartmentCorresponding author: Email: florin_sala@yahoo.comAbstract Sugar content is an element quality for wine grapes. Sugaraccumulation is a feature typical of the variety or the variety cultivated and isdetermined by climatic and technological factors. We evaluated thecomparative influence of two systems of fertilization, organic and mineral, onthe sugar content of grape variety Italian Riesling. Organic fertilizer wasprovided by manure in doses of 30, 40 and 50 t/ha. Mineral fertilizer was theNPK (S) type, fertilizer with zinc [15/15/15(+3+Zn)] applied in doses of NPK 50 ,NPK 100 and NPK 150 kg active substance (a.s.)/ha. Sugar content accumulatedunder the influence of the two types of fertilization ranged from 221.50±4,27g/l in case of control variant, 262.14±5,38 g/l in variant with NPK 100 kg/ha a.s.,organic fertilization providing a content of 255,30 g/l when applying 40 t/ha.Key wordsSugars, wine grapes,Riesling, organic andmineral fertilizersResearch concerning the variability of the flowersmorphological features of some orchid species from AninaMountainsBîtea Nicoleta - Daniela¹*, Madoşa, E.¹¹ Banat‟s University of Agriculture Sciences and Veterinary Medicine, Timişoara, Faculty of Horticulture andSylviculture* Corresponding author: Email: nicobitea@yahoo.comAbstract The Anina Mountains is one of the areas where the fieldliterature indicates a whole variety of orchid species. The purpose of thispaper was to evaluate the variability of the flowers morphological features ofsix orchid species identified in this area. The identified species were dividedinto two groups considering the appearance of the lip: species with three -lobed lip and species with the lip composed of two parts. The variability of thefeatures was assessed by biometric measurements made during the floweringseason of species. The analyzed features were divided into two groups: thegeneral morphological features of the flowers and the elements of the flowersmorphological features. The general morphological features of the flowershad the highest variability in all analyzed species.Key wordsorchids, flower, variability,Anina Mountains
The influence of the planting system on dry matteraccumulation in leaves and shoots of some varieties of peachtree (Prunus persica L.)Matei Traian Gabriel 1* , Madjar R. 1 , Gala R.A. 1 , Dinca L. 11 University of Agronomic Sciences and Veterinary Medicine, 59 Blvd. Marasti, District 1, 011464 Bucharest,Romania.*Corresponding author. Email: traianmatei1977@yahoo.comAbstract The peach tree ability to adapt due to the environmentalplasticity made possible for it to be grown in different areas with temperateclimate.The paper presents the behaviour of some new varieties introducedin Romania, Earlirich, Royal Estate, Rubirich, October Star and Late Luka,cultivated on GF 677 rootstock, in the Tatura trellis system (5.0 x 1.0 m), Vplanting system (5.0 x 1.5 m), Sibari Y (4.5 x 1.5 m) and Vertical axe (4.0 x1.5 m). The research was conducted in 2011 in the experimental field ofUniversity of Agricultural Sciences and Veterinary Medicine, Bucharest in aplantation established in 2008 on an area of 1000 square meters on a redpreluvosol. It was paid special attention to the difference given by thecultivated variety and by the modern planting systems in dry matteraccumulation in leaves and shoots of peach by determinations performed indynamics after fertilization with Fertisol and Folplant.Peach leaf content in dry matter (%) in the first moment of analysis, June 29,ranged from 38.11% (Earlirich in Vertical Axe planting system) to 44.94%(Royal Estate in Tatura trellis planting system), and in shoots from 38.93%(October Star in V planting system) and 52.48% (Royal Estate in Vertical Axeplanting system). Along with the vegetation the accumulation of s.u. in plantsrecorded values differentiated by the planting system, the largestaccumulation of s.u. is for the Earlirich variety in Tatura trellis plantingsystems of 68.63% s.u. in leaves and 64.45% s.u. in shoots. At the harvestingon 12 September for the V planting system we obtain the highest dry matteraccumulation in October Star of 66.48% in leaves and 70.05% s.u. for LateLuka in shoots. By the variance analysis it was highlighted the differencegiven by the planting system and the variety grown in dry matter accumulationin the main annual phenophases corresponding to the data of the sampling ofleaves and shoots of peach tree.Key wordspeach, dry matter, plantingsystemBehavior of some Pelargonium genera treated with Cycoganconcerning the growth and inflorescence of differentcultivation sublayersFironda (Casapu) Mihaela 1 , Băla Maria 11 University of Agricultural Sciences and Veterinary Medicine from Timisoara, Faculty of Horticulture andForestryContact address: Email: mariabalamonicabala@yahoo.comAbstract Pelargonium flowers have been appreciated by admirers ofdecorative plants using them as decorators of not only interiors, balconies,windows, but also of green spaces, parks, gardens, borders, platbandesKey wordszonal Pelargonium flowers,
