Insecticidal effect of herbal and aromatic extracts: myth or reality?
("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Bădeanu, Marinela; Daraban, G.; Șuteu, Daniela
The concern of the people for obtaining rich harvests and with the least expensive means has been and is continuous. The man of the past centuries, being more connected to nature than the present man and having the popular knowledge about the natural phenomena and about the plant species from the spontaneous flora, often used different plants in the control of the pests from the agricultural crops. Modern man, forced to return to nature, has devoted himself to the study of plants with combat potential, the first fruits of his work being then materialized in a series of synthetic products called pyrethroids, after the plant that provided them with information and substance: Piretrum cinerareifolium.

Ways to capitalize on the terraces of urban living spaces
("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Negrea Pașcu, Roxana; Zlati, Cristina; Bernardis, Roberto-Renato
The concept of terrace or green roof, arose from the desire to bring nature as close as possible. Thanks to the increasingly advanced technologies of recent years, we can achieve this goal even when we live in urban areas. The benefits of this work could be seen in the proposal of a design solution that aimed to reduce energy consumption and noise pollution, 60% rainwater retention and last but not least reduce the temperature of the roof by up to 7 degrees in the warm season and increase it by up to 5 degrees in the cold season. Thus, in this work, the suitability of some dendrological species for an arrangement located on a terrace located on the last level of a block of flats in the Tudor Vladimirescu neighborhood was analyzed. In carrying out this work, the choice of planting material was taken into account to ensure the decoration in a wide range.

Atmospheric dry tolerance of dendrological plants and ways of implementation in urban and periurban green spaces
("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Sandu, Tatiana; Trofin, Alina-Elena; Bernardis, Roberto-Renato
The impact of climate change increasingly depends on the measures and how affected areas, especially urban ones, manage to adapt by improving urban plans, increasing areas with green spaces, and adapting infrastructure to encourage the use of means of non-polluting transportation. But in the case of dendrological plants, atmospheric drought and pedological drought affect the normal development of vital processes due to cell dehydration, which in the short term leads to wilting of plants, and in the long term, can even lead to their death. All the properties of plant tissues to survive stressors are in fact plant resistance. In this sense, in landscaping in addition to the already known functions (sanitary, utilitarian, decorative), it is imperative to use resources rationally by proposing the use of dendrological and floricultural species as adapted to these stressful environmental conditions. This paper addresses the issues of high drought and its effects on plants, some aspects of the assortment of dendrological plants with drought tolerance suitable for the Iasi area and a proposal to implement these studies in the periurban landscape of Iasi by arranging a square in the peri-urban area of Iasi.

Evolution of grapes’ titratable acidity and sugar content in relation to canopy microclimate in the Cotnari wine growing region conditions
("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Minciună, I.P.; Patriche, Cristian-Valeriu; Colibaba, Lucia-Cintia; Cimpoi, Vlăduț-Ion; Irimia, Liviu-Mihai
High temperatures and high values of solar radiation during grape ripening lead to excessive sugar accumulations and low titratable acidity, with negative consequences on the sensory profile of the grapes and wines. The control of these unfavourable developments for the chemical composition of the grapes becomes a base condition for obtaining quality wines in the context of climate change. The research was carried out in 2020, on Tămâioasă românească wine grape variety in the Cotnari wine growing region, during the grape ripening season. The study revealed: positive correlations between the helio-thermal factors and grapes sugar content; negative correlations between the same climatic factors and grapes titratable acidity; and the influence of some cultural practices on grapes chemical composition. The grapes on the west side of the row have accumulated less sugars during ripening: 137.64 g / L on the west side and 145.72 g / L on the east side; grapes acidity on the west side was also more pronounced, with 13.61 g / L tartaric acid compared to 12.69 g / L tartaric acid on the east side. The 6% bentonite film treatment reduced the impact of temperatures and solar radiation on titratable acidity of the grapes, maintaining it by 0.83 g / L tartaric acid higher than the control.

Preliminary studies regarding the design a spiral of herbs
("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Chiriță, Raluca; Teliban, Gabriel-Ciprian; Cojocaru, Alexandru; Stoleru, Vasile
In the modern agriculture is a new trend, that of replacing cultivated areas with unproductive ornamental plants with productive vegetable species, using natural cultivation systems, with the purpose of educating young people, obtaining satisfaction by producing their own food, reducing (avoiding) the polluting factor and using leisure in a pleasant way. Against the background of reduced incomes or changes in the employment situation, the pandemic caused by COVID-19 caused changes in the perception of Romanians, in terms of food, housing, job, etc., a rethinking of lifestyle and a return to a minimalist and healthy life style. The new systems for growing vegetable, aromatic and spicy plants are inspired by nature. Thus, a non-conventional model for growing vegetable plants is the concept of spiral. A perfect concept to highlight a series of modern principles and ethics, based on a harmonious and efficient combination of new ideas and solutions, which can cope with economic, social and even climate change.

Agro-biological studies on the eggplant crops under plastic tunnel in organic farming
("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Ciubotăriță, Anamaria; Teliban, Gabriel-Ciprian; Cojocaru, Alexandru; Stoleru, Vasile
Solanum melongena L. are grown for their special nutritional intake in the body, such as carbohydrates, food salts, vitamins and polyphenols. Data from the scientific literature mention that the main method of establishing eggplant crops is through seedlings. Eggplants are a thermophilic species widely cultivated in different habitats, a low cultivation temperature (< 20 °C), as one of the major abiotic stresses, could significantly disturb the normal physiological and metabolic processes of eggplants. Eggplant crops play a main role in the world, with a high ecological plasticity, adaptable to different crop systems. Also, eggplant plants are affected by a large number of pathogens and pests, which is why solutions are sought using different methods of establishing the crops, under ecological farming. Thus, during the research, two eggplant cultivars (Mirval F1 and Black Pearl F1) were treated with organic and conventional fertilizers compared with control.

Ways of using dendrological species in plant compositions for hedges
("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Negrea Pașcu, Roxana; Zlati, Cristina
For the contouring and highlighting of landscaping, the most appreciated technique is the use of hedges, being also one of the most ornamental methods of delimitation, masking, protection or obtaining privacy within a site. Thus, this plant composition is increasingly addressed in both public parks and private gardens. Hedges are defined by fine, graceful and sinuous lines or statuary and geometrized, made of plant compound of low or imposing heights, and associated with elements such as water, buildings, alleys within the arrangements or even together with other plants. In order to illustrate this concept, in this paper we studied the compatibility of the use of special dendrological genera from an ornamental point of view, whose biological characteristics allow them to be used in compositions such as hedges. For each of the five genres studied, two types of systematization were used, thus being able to determine their sustainability over time.

("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Cojocariu, Mirela; Chelariu, Elena-Liliana; Chiruță, Ciprian; Amișculesei, Petronica; Bulgariu, Emilian
Annual, unpretentious flowering species, Begonia semperflorens 'Big', stands out due to its aesthetic valences constant throughout the growing season. The compact appearance, the abundant and long lasting flowering, the dense and healthy foliage have caused it to be more and more frequently used in the landscaping of parks and urban gardens. This paper aims to study the behavioural pattern of the begonia 'Big' variety in vertical systems for green façades, in the climatic conditions of the N-E part of Europe. The experiment was carried out on height levels, applied to façades oriented towards the four cardinal points with the purpose to conduct a comparative analysis of behaviour, depending on the amount of natural light received specific to each orientation. The study found that Begonia semperflorens 'Big' grown in vertical systems behaves very well regardless of the cardinal orientation of the façade. It is noted, however, that better results were achieved on the north-facing façade in terms of survival rate and coverage.

("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Amișculesei, Petronica; Chelariu, Elena-Liliana; Apostol, Maria; Hangan Istrate, Ana-Maria-Roxana; Draghia, Lucia
The behavior in culture of the Gladiolus byzantinus species, in the ecological conditions of the NE area of Romania, has been studied for several years at the University of Agricultural Sciences and Veterinary Medicine Iaşi. In this paper we determined the way in which G. byzantinus corms influence the growth and development of plants, respectively their decorative value. The establishment of experimental crops it was made in November 2019, using corms with different mass: > 10g (V1), 7-9 g (V2) and <7g (V3). Observations and determinations performed in 2020 showed that from corms with a mass > 10g (V1) were obtained plants with the highest number of shoots, flower stems and flowers. At the variants from the smaller corms, respectively V2 and V3, the results were inferior, except for the height of the floral stem. From a phenological point of view, the beginning in vegetation, the formation of floral stems, the onset and duration of flowering, were to the advantage of the V1 variant.

("Ion Ionescu de la Brad" Iași University of Life Sciences, 2020) Constandache, C.; Dincă, L.C.; Tudor, Ciprian
The harvesting importance and the introduction in economic circuit of non-wood forest products, especially forest fruits, mushrooms, game reside both under economic aspect, representing a proportion over 10% from the business number realized by many County Forest Administrations and mostly from the social point of view, through the capital amount in rural zones where the population incomes come almost exclusive from agricultural activities. The aim of this paper was to highlight the most important non-wood forest products from Teleorman County and to analyze the social and economic impact of those from Teleorman county, Romania. The NWFPs were grouped in four categories, namely Mushrooms (Boletus edulis and Lactarius piperatus), Tree products (Linden flowers, oak seeds), Understory plants (Rubus idaeus, Mentha piperita) and Animal origin (Lepus europaeus, Squalius cephalus). Within the research method it was used the analytic hierarchy process (AHP) which use an interface of multi-criteria system. Based on the processing data in the Expert Choice Desktop software, it was found that the most important non-wood forest products were forest fruits (raspberries), mushrooms (Penny bun) and those of animal origin (European hare). This kind of analysis it can be addressed to the managers who wants to perform the activities inside of the company such as making some statistics about the relative consumption of some products.
