Studies on the influence of genotype and culture mediacomposition on growing explants in the in vitro initiation phaseTudor Radu C.M. 1* , Radomir Ana Maria 11 National Research & Development Institute for Biotechnology in Horticulture Stefanesti, Sos. Bucuresti-Pitesti, no. 37, CP 117713, Arges, ROMANIA*Corresponding author. Email: mihai_radutudor@yahoo.co.ukAbstract To initiate ‘in vitro’ cultures there were sampled shoots fromroses grown in soil and in the greenhouse and from blackberry grown in pots.The used roses genotypes were Thea hybrid (Akito, Crimson Glory,Baccara) and climbing roses (New Dawn and Ilse Krohn Superior).The meristemes used for ‘in vitro’ culture initiation were sampledunder the magnifying glass in laminar air flow.For the meristemes growing it was assured a 22-24 0 C temperature inthe room and 16 hours of light with 2500 lux intensity.Nutrient mediums used for the initiation phase of the cultures weredifferent in composition.The rose varieties have performed well in the growth of explants, thedifferences being the result of interaction of genotype with the culture mediumcomponents.Regarding the influence of culture medium, as abiotic factor, it was found thatthe highest values were obtained for explants grown on culture mediumMurashige - Skoog, with 0,004 mg / l naftilacetic acid / 2 mg / lbenzilaminopurine. Decreased concentration of cytokinine led to lowerpercentage of grown explants.The growing of blackberry explants was influenced by the genotype and bythe culture medium components.Key words‘in vitro’ culture, culturemedium, Thea hybridsResearch concerning the content of cations and anions in thegroundwater of the Timis riverAntoanela Cozma 1 , A.Lazureanu 2 , Alina Balint 2 , Alexa Ersilia 31 Banat‟s University of Agricultural Sciences and Veterinary Medicine, Department of Exact Siences,Timisoara, Aradului Street no.119, RO-300645, Romania2 Faculty of Horticulture and Forestry, USAMVB Timisoara, Faculty of Agro-Food Processing TechnologiesTimisoara*Corresponding author. Email: antoanelacozma@yahoo.comAbstract In this study the objectives is the monitorizing of the cations(iron and manganese) and anions (sulfates, phosphates, chlorides) content ofgroundwater in the five prelevation places situated on the Timis river way,during the 2004 year. The obtained results were compared to the limit valuesof the chemical indicators established in actual legislation. The obtainedvalues showed exceeding of the maximum admitted limits at points locateddownstream from pollution sources.The poluted sources are caused bydischarge wastewater stations appeared in the sewage channel of Lugoj cityand also from Bega-Timis discharge channel.Key wordsanions, cations content,chemical parameters,pollution sources
Research on effective herbicides in combat weeds in the Westcountry vineyardsVior M. 1 , Cârciu G. 11 Banat University of Agricultural Sciences and Veterinary Medicine Timişoara, Faculty of Horticulture andForestry;*Corresponding author. Email: vior_marius@yahoo.comAbstract The purpose of this study was to determine the composition ofweed flora of orchards and their chemical combat effectiveness through theapplication of herbicides. The research was conducted during the years 2009and 2010 and had as its object of study and combat the spread of weedspecies in vineyards located in three separate locations: Growing PlantationRecaş, Didactic Station Timişoara and Growing Plantation Buziaş. Flora waspredominantly composed of perennial plants in particular monocotyledonousand Agropyron repens, Cynodon dactylon latter holding the majority.Agropyron repens is currently the highest weed spread in vineyards, followedby annual dicotyledonous species. Ensure the highest application rate ofherbicides to combat weeds in particular by using high-spectrum herbicidessuch as Glyphogan, Roundup and Touchdown.Key wordsdegree of weed, culture,vineyards, herbicidesInfluence of fertilization and density on production of springoats variety JeremyRusu S. 1 , Cârciu G. 11 Banat University of Agricultural Sciences and Veterinary Medicine Timişoara, Faculty of Horticulture andForestry;*Corresponding author. Email: adirusnacu@yahoo.comAbstract Research conducted in 2009 come to spring oats argue theimportance of culture in the west of Romania. The results are in direct linewith growing applied technology. Fertilization thus directly affect the level ofproduction output varied between 23, 50 q / ha (V 6 N 120 P 60 K 60 ) and 11, 50 q /ha (V 1 -fertilization).The importance lies in the fact that oats oat grains are a valuable feedhorses being used in feeding, breeding, youth, dairy cows, poultry, legumeand mixed with a mash made a spring of very good quality.The investigations conducted so far shows that leverages Spring oats bestnitrogen fertilizers.Key wordsculture, variant, variety,fertilizer production
