Flor yeast cellular components
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Moreno García, Jaime; Dumitriu Gabur, Georgiana-Diana; García Martínez, Teresa; Millán, María Carmen; Mauricio, J.C.; Moreno, Juan
Flor yeast develops a biofilm on the wine surface after the alcoholic fermentation of grape which remains during the “biological aging” process in the elaboration of Sherry wines. The aim of this study is to identify cellular components which role might be essential for the yeast survival under this process. A proteome analysis was carried out for a flor yeast grown in a biofilm forming and in a reference non-biofilm forming conditions and proteins annotations to cellular components were performed by using the SGD database. Higher abundant proteins in the biological aging condition localized mostly in the cell wall, extracellular region and peroxisome; in the reference condition higher abundant proteins belong to the cellular bud and site of polarized growth. Further works dealing with genetics, and also utilization of different flor yeast strains could be considered and aimed to improve the quality of Sherry wines in a near future.

The influence of giberellic acid on callas grown in pots
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Arhip Însurățelu, Ioana-Cristina; Draghia, Lucia
This paper presents four Zantedeschia cultivars ('Cameo', 'Black Star', 'Picasso', 'Black Eyed Beauty') grown in pots, to which determinations and observations were made on the effect of treatment with gibberellins. Treatments were applied to the tubers, before planting, with 250 ppm GA3 solution. The results revealed that treatment with GA3 had different impact on the studied cultivars: at the cv. 'Cameo' the emergence of floral stem was delayed, the growing season was shortened and the length of floriferous stems was shorter; at the cv. 'Picasso' they shortened the vegetation period and increased the number of flowers / plant; at the cv. 'Black Star' they led to early flowering, shortening the growing season and increasing the number of flowers / plant; at the cv. 'Black Eyed Beauty' they caused earlier flowering and shorten the length of the flower stems.

Stormwater management: the role of urban trees
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Pohoață Lupu, Oana; Draghia, Lucia
The influence of urban trees in management of stormwater is to moderate the microclimate, to reduce the ”urban heat island” (UHI) through shading and evaporative cooling and also, by reducing glare and insolation. Trees intercept a portion of rainfall that evaporates and never reaches the ground. Surface runoff is avoided when precipitation is held on foliage until it returns into the atmosphere. The capacity of water interception is influenced by biological and structural characteristics of the trees (species-specific factors), and by climatic conditions (site-specific factors). The purpose of this paper is to study the water storage and evaporation capacity of the three important tree species identified in a typical urban of Iași: Acer platanoides L., Aesculus hippocastanum L. and Tilia sp.

Applying the CHAB concept at horticultural tunnel greenhouses heated with biomass
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Murad, E.
For heating tunnel horticultural greenhouses in cold season applies the concept CHAB (Combined Heat And Biochar production) which synergistically incorporating thermal energy and biochar production from biomass gasified with TLUD process that produces fuel gas and 12..15 % biochar. Biochar is a vegetal active carbon, sterile, pH > 9 and a high adsorption capacity, used as agricultural amendment and carbon sequestration. Sold with 400...1000 €/t can get zero or negative costs for heat produced. Simulate experiments were performed to a model of the 200 m2 tunnel greenhouses are grown tomatoes. For heating in four cold months consumed 13 t chopped and dried tomato stalks and resulting 1.8 t biochar which incorporated in the ground leads to a negative balance of -6.34 t.CO2/year. Average daily cost for fuel is 5,91 €/day without a biochar recovery and -4.78 €/day for a biochar recovery with price of 680 €/t in EU.

About the radioactivity of some agricultural products from areas near Crucea uranium mine
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Oancea, Servilia; Pădureanu, Silvica; Cazacu, Ana; Oancea, Andrei-Victor
Events like the nuclear accidents that occured at Cernobyl in Ukraine and Fukushima in Japan have raised public awareness to the many dangers of working with radioactive elements. When using nuclear energy it is well known that any controlable nuclear source can in certain circumstances become uncrontrollable. As a result the radiological monitoring of the enivironment has increased both in the vicinity of nuclear plants and of uranium mines. The aim of this paper is the study of local products sampled from areas near the Crucea uranium mine found in the county of Suceava. The results of our measurements show that the radioactive activity of mushrooms is significantly higher than the cosmic background showing that mushrooms have the potential of being used as bioindicators for radioactivity.

Ornaments of vegetal inspiration in orthodox architecture
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Cehan, Agata-Mihaela; Gheorghiță, Constanța-Carmina
The Church is the only architectural program able to illustrate the cohesion between matter and spirit. Faith acts as a binder of the relationship between religious experiences, aesthetic emotions and rational solutions. The structure materializes the sacred, while the accompanying associated arts assigns aesthetic and spiritual meanings. Worship spaces consist on the basis of rigorous canons which are founded on symbolic meanings. Regarding these religious ideologies, the vision of these spaces is probative for revealing their concept of life, world and divinity. The symbol, a link between visible and imaginary, between concrete and intuitive, expresses clearly the relation between divine and world. It and represents an indicator to what is beyond it, but remains always linked in the present reality. This paper aims recognizing and interpreting the symbolic elements of vegetable inspiration used in the Orthodox worship spaces, metaphorical images of archetypal space.

Urban green. The potential of city’s residual areas
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Dumitrașcu, Aurora-Irina; Nica, R.M.; Corduban, C.G.
Nowadays, the contemporary cities are evolving at an accelerated pace, aspect that brings forward new sets of problems to be dealt with. Among the most common urban issues we can identify the lack of high quality public spaces, insufficient parking spaces, and the presence of decommissioned (disused) industrial sites that fragment the overall appearance of the residential areas. Regarding the aforementioned issues, this paper will focus on the opportunity to provide potential directions of development for urban landscape through the increasing of green areas. As such, the existing residual urban spaces can provide a solid framework for future opportunities and the increasing of green areas per citizen can be applied for a sustainable urban recovery and reconversion.

Reshaping the cityscape through small landscape designs
(Editura “Ion Ionescu de la Brad” Iasi, 2014) Grigorovschi, M.; Gheorghiță, Constanța-Carmina
The landscape-designs within the city need to fulfill a number of conditions in order to meet the essential purpose of increasing the quality of life and to contribute towards increasing the urban comfort. In the urban texture of Iasi city a multitude of abandoned, undeveloped, deconstructed public spaces can be found, which, besides a poor quality urban image and can become unsafe for the public. We will refer mainly to the spaces related to the pedestrian traffic and those located in their immediate vicinity, spaces of small dimensions, unutilized, without a precise destination, with a predominantly mineral structure and with constitutive elements (fronts, surroundings, pavements, constructions etc.) without special volumetric, architectural and artistic qualities, or even completely deconstructed. Through this paper we aim to identify such areas in Iasi and propose small landscape-designs who will increase the quality of urban space, will favor social contact, and will generate an improved image quality of unused and abandoned urban spaces.

(Editura “Ion Ionescu de la Brad” Iasi, 2014) Berar, C.; Lisandru, Tabita-Teodora; Silivășan, M.; Băla, Maria; Toța, Cristina
In the planning proposal for green space in the Arad County Hospital left the idea of creating an environment specifically designed to provide favorable conditions for the recovery of health and recovery of people in distress. Elements were used to give patients a state of putting the fore chosen vegetation and its effects on people. Plants create an environment of welfare reducing blood pressure, stress and giving a general state of good health physically and mentally. This was done by choosing vegetation for the effects it has on the environment and on people. Species were used for air filtration and solar radiation. The arrangement was based on the ability of the hospital to receive a large mass of people. Resting places are in high numbers, the spread over the entire surface and paths linking all hospital bodies.

(Editura “Ion Ionescu de la Brad” Iasi, 2014) Niculaua, Marius; Moroșanu, Ana-Maria; Vararu, Florin; Moraru, I.; Nechita, Constantin-Bogdan; Cotea, Valeriu V.
Volatile compounds are plant metabolites and are resulting in fermentation processes. They are important factor for evaluating the quality of wines from technological point of view and allows in most cases to characterize sensory characteristics felt by consumers at a fundamental level. In this case are presented some wines produced with grapes from the 2006 harvest as following: Cioinic, Creață de Banat, Cruciuliță, Fetească albă, Fetească regală, Frâncușă, Gordan, Mustoasă de Măderat, Zghihară varieties. For these wines physicochemical characterization was performed to better understand the quality of the end product. In these wines were identified by ITEX-GC-MS method a series of fatty acids such as isobutyric, hexanoic, octanoicdecanoic acids and fermentation alcohols 2- and 3- butanols that varied greatly depending on the variety from which they originated. The data were compared with the products of the fermentation of refined sugar and alcohols highlight differences in fermentation batches.

Using gas-chromatography to distinguish the wine and still fermented beverages
(Editura “Ion Ionescu de la Brad” Iasi, 2024) Nechita, Constantin-Bogdan; Cotea, Valeriu V.; Niculaua, Marius
For several years, in order to harmonize the Romanian legislation with the European one, was introduced the notion of "still fermented beverages". This is a beverage obtained by fermentation, but it is not explanained what raw materials are used in the production process and their contribution to the alcoholic strength of the final product. For this reason, some manufacturers are tempted to sell such drinks as the wine. We conducted a series of refermentation of pomace from red and white winemaking and volatile compoundsfrom these drinks were analyzed by gas chromatography coupled with mass spectrometry. The mass spectra of the compounds were compared with the spectra from Wiley and other libraries. We made an identification of volatile components comparing them with those identified in wine.

(Editura “Ion Ionescu de la Brad” Iasi, 2024) Tarțian, Alexandru-Cătălin; Cotea, Valeriu V.; Niculaua, Marius; Colibaba, Lucia-Cintia; Nechita, Constantin-Bogdan; Moroșanu, Ana-Maria
This study pursues the influence of the pedoclimatic conditions on the physico-chemical characteristics of the wines obtained in “Vasile Adamachi” Research Station of Iasi.Fetească albă and Busuioacă de Bohotin wines were obtained by the same wine-making technologies and in the same year of production (2012 for Fetească albă wine and 2013 for Busuioacă de Bohotin wine). Therefore, it can be followed only the influence of the pedoclimatic conditions from the vineyards where the grapes were used for winemaking. The main parameters that will be followed to determine the physico-chemical composition of wines studied are: sulfur dioxide, volatile acidity, total acidity, density, concentration of alcohol, reducing sugars, total dry extract, nonreductive extract, phenolic compounds and chromatic characteristics. By analyzing these parameters it can be established the degree of influence that have the pedoclimatic conditions on typicity of the grape variety and on the quality of wines produced from them.

(Editura “Ion Ionescu de la Brad” Iasi, 2024) Postolache, Elena; Ciubucă, Aurel; Bîrliga, N.
The climatic conditions influence the characteristics of the grape and wine composition. Plus sufficient rainfall above average and monthly distribution in 2013 have increased the potential specific grain variety and obtaining alcoholic wine than in May 2012 (severe drought) when grapes are left underdeveloped by blocking photosynthesis (high temperature, foliar burn) with negative repercussions on the accumulation of sugars without affecting color compounds. Wines of 2012 compared to the year 2013 are less alcoholic but with high bet on anthocyanins, polyphenols extract unreduced and staining intensity. In terms of organoleptic wine of the year 012 are higher than those in 2013 by extractivity, orietal flavors and brightly colored.

Physico-chemical analysis of wines produced from local varieties in Romania and Republic of Moldova
(Editura ”Ion Ionescu de la Brad” Iasi, 2014) Luchian, Camelia-Elena; Cotea, Valeriu V.; Patraș, Antoanela; Codreanu, Maria; Colibaba, Lucia-Cintia; Kokkinofta, Rebecca
The natural conditions extremely favorable from Romania and Republic of Moldova, near the Danube Delta and the Black Sea, in latitudes similar to those in France, have favored over the time an expansion of lands cultivated with vines. Viticulture and wine production were basic occupations of people from this territory. Over time under the influence of many climatics, economics and historicals factors were obtained grape varieties adapted to the local conditions. Certain viticultural practices have been developed who contributed to the individualisation of wine from two different geographical areas. Wine made from Băbească neagră and Fetească neagră two local varieties cultivated in Romania and Republic of Moldova differentiates both by physicochemical and organoleptic characteristics, the aim of this paper being a comparative analysis of physicochemical composition and organoleptic properties of these wines. As a result for physico-chemical and organoleptic assays of Fetească neagră si Babească neagră wines from Iasi and Chateau Vartely vineyards, significant differences were identified.

Studies of the influence of some conditioning treatments on some volatile compounds in Fetească Albă wines
(Editura ”Ion Ionescu de la Brad” Iasi, 2014) Colibaba, Lucia-Cintia; Cotea, Valeriu V.; Rotaru, Liliana; Niculaua, Marius; Vararu, Florin; Luchian, Camelia-Elena
Volatile compounds of Romanian wines made from local grape varieties considered neutral from a sensorial point of view are not sufficiently studied. This article mainly aims at underlining the influence of conditioning/fining treatments of wines, specifically their influence on physicochemical composition and aroma profile of Fetească albă wines in Cotnari vineyard. Five experimental samples were obtained as follows: FA M - raw new wine before fining; FA V1- after treatment with potassium sorbate, FA V2 – cross-flow filtration, FA V3 after treatment with gum Arabic, FA V4- after treatment with cellulose gum CELSTAB®. The fining treatments applied to Fetească albă wines lead to changes in the concentration of flavor compounds through their adsorption or catalyse reactions leading to the formation of higher weight molecular compounds with a different sensory impression.

Influence of climatic conditions on the incidence of the entomofauna useful on vineyard ecosystem Dealu Bujorului
(Editura ”Ion Ionescu de la Brad” Iasi, 2014) Tabaranu, Gabriel; Enache, Viorica; Donici, Alina
This paper presents research conducted to SCDVV Bujoru in 2012 - 2013. Lately, the problem of protecting biodiversity at the ecosystem, species and populations has become increasingly vital to reduce human impact on the biosphere. Vineyard ecosystem is defined as the functional unit of the biosphere created and controlled by humans in order to obtain high yields of grape quality and the economic and social conditions more favorable. Pesticides used in fighting pathogens vine attached to their favorable effect, increase their aggression and contribute to environmental pollution and the grape harvest, when they are used rationally. In the last two decades, public opinion in general and Romanian scientific research proved particularly sensitive to the environment and human health. The research focused on the study of epigeal fauna (the entomofauna useful) vine plantations due to the fact that any pesticide treatment has more influence or less on its specific structure, but also the quantity of individuals of the same species that meet various agricultural ecosystems (Ball et al., 1986).

Research on minimizing the disruptive effect of climate change on viticulture by applying adapted technologies
(Editura ”Ion Ionescu de la Brad” Iasi, 2014) Enache, Viorica; Donici, Alina
The research was conducted within SCDVV Bujoru, Galati county in the climatic conditions of the years 2012 to 2013. Experienced technological factors (soil system maintenance and fruit load) differentially influenced the intensity of physiological and biochemical processes with direct consequences for grape production and quality. A stronger positive influence on the production of grap, to exercise maintenance system, ground biggest productions were obtained when total mulching with straw. High temperatures combined with poor rainfall during the growing season and diurnal average consumption vine led to soil moisture differentiated soil in system maintenance. In a dry year, grape production was influenced by soil maintenance system, the maximum yield for variant partial mulching. In a normal year in terms of climate stands out partial mulching option, followed by mulching total. Systems maintenance of soil by mulching (total or partial) and minimum tillage exerted a positive influence on the quality of grape production. The reduction of the load of the fruit (20 and 40%) resulted in the maintenance of the systems of the soil to increase the content of sugar in the grapes and a decrease in acidity of the must, which yielded high values of the index gluco-acidimetric, adverse obtaining quality wines and typical.
