Research Regarding the Influence of Folliar Fertilization on Plant Assimilation, Grain Yield and Quality of Wheat, in the Transylvanian Field Conditions
Get PDFThe researches were carried out during the 2016-2017 vegetation period using the wheat variety Andrada and the perspective line T. 123-11 created at ARDS Turda, which were treated with 3 types of foliar fertilizers: Folimax Gold (V2 -2 treatments, V3-3 treatments) Folimax Oleo (V4-2 treatments and V5-3 treatments) and Microfert U (V6-3 treatments) applied in two and three treatments in different phenophases of crop development. The measurements on the assimilation (An = μmol CO2 m-2s-1) and leaf evapotranspiration (Evap- mmol H2O m-2s-1) were performed on a stindard leaf, 5 days after the last foliar fertilizer treatment in June, for each variant, from the 3 reps. The application of nitrogen foliar fertilizers resulted in the increase of the leaf surface, the nitrogen content of the leaves, increasing net assimilation for all variants, evapotranspiration and production. Andrada wheat variety advanced a higher oscillation of net assimilation (An) (from 28.5-32.7 μmol CO2m-2s-1), higher evapotranspiration (Evap) (1.97-2.33 mmol H2O m-2s-1) and the production was over 7300 kg/ha in foliar fertilized variants in all three vegetation phenophases. The perspective line T. 123-11 recorded slightly lower assimilation values (An) than Andrada wheat, being more clustered (from 30-31.7 μmol CO2 m-2s-1) and evapotranspiration (1.60-1.90 mmol of H2O m-2s-1) and also productions of more than 8100 kg/ha in 3 foliar fertilization variants, using the foliar fertilizer more efficiently and water in tissues. The highest quality indices were obtained with 3 foliar fertilization variants, obtaining values between 10.9 and 11.3% for proteins, for gluten between 21.3 and 21.6% and for the Zeleny 30.8 and 34.1% for Andrada lower than T. 123-11 with protein values between 11.7 and 14.0 % and gluten content of 23.4 and 28.3%, respectively the Zeleny index from 40.0 to 54.4%
GALIUM SPECIES - POLYPHENOLIC CONTENT AND THEIR ANTIOXIDANT POTENTIAL
Get PDFThe genus Galium is well represented in the spontaneous Romanian flora. Three Galium species are more commonly used in therapy, Galium aparine L. or cleavers, Galium odoratum (L.) Scop. or woodruff and Galium verum L. or lady’s bedstraw. Tinctures preparated from aerial part of these species was chemically analyzed and their antioxidant activity was evaluated. The total phenylpropane derivatives and total flavonoids contents were determined by spectrophotometrically methods. The antioxidant capacity was evaluated in vitro by FRAP, CUPRAC and xanthine oxidase inhibition methods. The results showed that the tinctures were rich in polyphenols and had a strong antioxidant capacity, which is confirmed by all used methods. A good correlation between the antioxidant capacity and the content of polyphenols could be highlighted

Research has focused on the influence of biostimulators on germination capacity, the height of stem, also we determined the total chlorophyll content with the CCM plus 200 and the stomatal conductance with SC1 leaf porometer.The bifactorial experience was conducted in a pots experiment in randomized blocks with three repetitions. The application of biostimulants (Cropmax and Atonik) was done every ten days by foliar spraying throughout the vegetation period.Biostimulants in this study had a positive influence of the physiological processes followed in the three cultivars of beans. These products can be used successfully for both and the treatment of seed and the treatments applied to the phases of the growing season. The best results were recorded of bean plants treated with Cropmax
Research Concerning the Fighting of Polystigma rubrum Fungi under the Climate Conditions of Șomcuta Mare Area
Get PDFIn this study, our goal was to survey the influence of the climate conditions, the behavior of the Centenar and Anna Spath varieties on the attack of the Polystigma rubrum fungi during the two experimental years (2013, 2014), in order to make recommendations for new plantations. Nine fungicides were tested, being determined their biologic efficiency, in order to identify the most efficient products. The experimental research was performed during 2013 and 2014, in a fruit tree farm belonging to SC Pomicola SA trade company in Somcuta Mare, Maramures county. The attack was calculated by determining the frequency, intensity and the attack degree. The agrometeorological data were recorded using the AgroExpert system, for surveying the biology of fungi. The linear-interrupted laying method was used, each made up of 5 plants/variant in three repetitions/product. The biologic efficiency of the tested products was lower at the Anna Spath variety than at the Centenar variety due to its sensitivity; the recommended products: Folicur Solo 250EW, Dithane M45 and Syllit 400 SC were the most efficient in the fungi combating

Arbuscular Mycorrhizae Morphotype-Based Identification Using Optical Microscopy
Get PDFStructures of different AM taxa found in symbiosis with plants can stain from intense to weak after roots preparation for microscopy. Although arbuscules are distinctive features of AM, their overall shape can vary in association with two proliferation types: Arum and Paris. Auxiliary cells and vesicles are not omnipresent. Intraradical hyphae can present divergent types: straight/coiled, with “Y”/“H” connections. According to spore formation, there are five main AM morphotypes. Spore-based species identification takes into account: color, shape, size of spores and sporocarps as well as structures associated with them (cicatrix, pedicel, peridium, sporiferous saccule, sporogenous cell, subtending hypha). Description of subcellular structures of spores targets phenotypic and biochemical properties of layers using Melzer’s reagent and morphology of pre-germination structures when present

Aspects of Chemical Composition and Somatic Cell count of Cow Milk Marketed at Dispensers
Get PDFMilk quality is influenced by many factors: lactation, fat, protein, lactose, number of somatic cells. In order to process raw milk and compare with criteria of quality and food safety the Regulation of European Parliament and the council no. 853/2004. Analysing the total number of somatic cells (SCC) in the period July-August 2017 it is noted that in case of samples collected from first automatic milk dispenser exceed 2 times the maximum admissible values and the samples collected from second automatic milk dispenser are up to the maximum allowable values which show that milking hygiene and animal health are at the European standards required. Analysis of fat content for both cases indicates that it is within the standard values for cow's milk and fat variations for DM1 samples are very low at temperatures above 30 degrees Celsius which shows that high temperatures do not influence these parameters. The biological material study was represented analysed by 30 samples of milk from only two cow milk dispensers functional located in this period in Cluj-Napoca city. These samples were collected at the same time period during July-August months. The aim of present study is to determine whether milk marketed through dispensers under the high temperature conditions specific to this period is affected in terms of qualitative parameter analysis
