The effect of genotype and water stress on root growth insome alfalfa varietiesDecuseara Carmen 1* , Nedelea G. 11 Banat‟s University of Agricultural Sciences and Veterinary Medicine Timisoara, Faculty of Horticulture andForestry*Corresponding author. Email: carmendecuseara@yahoo.comAbstract Drought is a major environmental determinant of plant growthand productivity. Therefore, understanding the mechanisms of plant toleranceto drought stress is a crucial environmental research topic. Osmoticadjustment is one trait, which plays an important role in sustaining growthunder water deficit conditions. Analysis of alfalfa growth has shown that itresponds to an onset of drought by a reduction in shoot and root elongation.The aim of this study was to assess the effect of polyethylene glycol on rootgrowth of some alfalfa varieties and to identifying the superior genotypes fordrought tolerance. Both, genotype and PEG treatment have a distinctlysignificant influence on the root growth to studied varieties, due to low andinsignificant influence of environmental conditions. Also the combined effectof two factors had a significant influence on the root length. Based on theobtained results can be summarized that under osmotic stress conditionsSatelit and Granat varieties have expressed the highest tolerance.Key wordsalfalfa, genotype, waterstress, root growthThe effect of genotype and water stress on germination abilityof seeds in some alfalfa varietiesDecuseara Carmen 1* , Nedelea G. 11 Banat‟s University of Agricultural Sciences and Veterinary Medicine Timisoara, Faculty of Horticulture andForestry*Corresponding author. Email: carmendecuseara@yahoo.comAbstract Suitable germination and drought tolerance alfalfa by selectionof drought tolerant genotypes is very important, in breeding programs for thiscrop. The study of the influence of the drought using osmotic solutions is oneof the methods in the study of resistance during the germinal phase. The aimof this study was to assess the effect of polyethylene glycol on germinationability of some alfalfa varieties and to identifying the superior genotypes fordrought tolerance. Both genotypes (varieties) and PEG treatment, have a realand significant influence on seeds germination ability, the PEG treatmenthaving had the greatest influence on this character. It is also noted that thecombined effects of the two factors had a significant influence on germinationability of the seeds for the studied varieties. In the conditions of low values ofthe osmotic stress, Sigma and Selena varieties showed the lowestgermination ability, significantly inferior to other varieties. In case of highvalues of the stress, Satelit variety recorded the best tolerance, followed byGranat and Dorina varieties, while Selena variety show a high sensitivity.Key wordsalfalfa, genotype, waterstress, germination

Email: petredraghicioiu@yahoo.comAbstract These researches tried to put in evidence the influention ofsome technological factors over one assortment of lettuce cultivated in field inMay – June 2011 period at the Didactic Base Timişoara. The assortment oflettuce taken in experience vas represented by the next lettuce lines andvarieties: AS 104, AS108, AS 6119 (Geodis) and AS 6123 (Hedonis).The technological factors had an important influence over the experience andwere represented by the natural fertilization products (b factor) and theplanting density (c factor). These assured final productions with a highteconomic level.Keywords:lettuce,natural fertilization products,plantingdensity,cabbage weight,production dynamics.
