Influence of treatments with growth retardants on the ornamental properties of Lagerstroemia indica L. plants
(Editura “Ion Ionescu de la Brad” Iasi, 2024) Barbu, Alis-Valentina; Apostol, Maria; Lupoae, Paul; Amișculesei, Petronica; Cantor, Maria; Draghia, Lucia
The behavior of the species Lagerstroemia indica under the ecological conditions of the south-eastern part of Romania has been studied for several years at the Botanical Garden of Galati. The present experiment analyzed the effect of treatment with Alar 85 SG (growth retardant based on daminozide) on L. indica plants obtained from seeds and grown in pots under unprotected conditions. Based on the observations it was found that the reduction in plant height, the increase in the number of branches, the earliness of flower buds and flowering initiation, and the prolongation of flowering time of the plants were directly proportionally influenced by the concentration of the growth retardant used as 0.3% and 1%. The results recommend the treatment with Alar 0.3% as efficacious, considering that the effect on other characters ensuring flowering quality (inflorescence length, number of inflorescences / plant, number of flowers/inflorescence, density of flowers in inflorescences and flowering capacity of plants) was diminished by increasing the concentration to 1%.

The effect of supplemental oxygenation and LED lighting on root development and carbohydrate content in lettuce grown in the NFT system (Nutrient Film Technique)
(Editura ”Ion Ionescu de la Brad” Iasi, 2024) Nițu, Oana-Alina; Ivan, Elena-Ștefania; Gheorghe, Marinela
The NFT system is a type of hydroponics where a thin layer of nutrient solution constantly circulates over the plant roots. This ensures continuous access to water, nutrients, and oxygen, which promotes rapid and healthy plant growth. Controlling the conditions in this system, such as oxygen levels and lighting, plays a crucial role in the efficiency of photosynthesis and, implicitly, in carbohydrate content. Oxygen is essential for plant growth, especially for the roots, as it aids in root respiration. In hydroponic systems like NFT, water and nutrients are recirculated, and the oxygen level in the nutrient solution can affect plant metabolism, including carbohydrate synthesis. Supplemental oxygenation of the nutrient solution can improve nutrient uptake and photosynthesis, which could increase carbohydrate levels in lettuce. LED lights are frequently used in plant cultivation because they are energy-efficient and can be adjusted to provide the light spectrum necessary for photosynthesis.

Wastewater is generated at every stage of wine production, mostly from cleaning equipment, floors, tanks, barrels and bottles. Wastewater contains heavy metals and other toxic compounds that can pose environmental hazards risks. This study quantified the concentrations of key heavy metals (lead, chromium, manganese, copper, and iron) in wastewater from a winery at different stages of the winemaking process. The results showed that all heavy metal concentrations were consistently below the maximum permitted limits, in compliance with environmental regulations. Lead concentrations decreased significantly from 24.03 μg/L after pressing stage to 9.44 μg/L after bottling stage. Manganese showed fluctuations throughout the process, while copper concentrations decreased significantly, indicating effective removal of residues. Overall, the findings suggest that the winemaking process effectively reduces heavy metal concentrations in wastewater, ensuring compliance with environmental standards.

Biodiversity hotspots in urban design: the role of perennial meadows in replacing ornamental turf in institutional settings
(Editura ”Ion Ionescu de la Brad” Iasi, 2024) Vladimir Asiminei, Ina; Cojocariu, Mirela
Recent studies in urban landscape design highlight the importance of green areas in cities, emphasizing their essential role in addressing the climate crisis and biodiversity decline. In recent years, creating urban meadows has been globally recognized as a practical solution for tackling these issues and bringing social benefits. In urban design, perennial meadows represent an ecological alternative to traditional ornamental lawns, often requiring considerable resources and contributing to biodiversity loss. Implementing perennial meadows in institutional spaces, such as university campuses or administrative complexes, can create biodiversity “hotspots”, supporting local species and improving environmental quality. This paper proposes the development of a perennial meadow design to replace the existing lawn in the outdoor space of the Faculty of Biomedical Engineering at the “Grigore T. Popa” University of Medicine and Pharmacy in Iasi, evaluating the success of the initiative by analyzing three key factors: impact on biodiversity, improvement of local climate conditions, and benefits for the institution’s users.

Preliminary results on growing early cabbage in organic system
(Editura ”Ion Ionescu de la Brad” Iasi, 2024) Zaharia Rogojină, Mihaela; Stoleru, Carmen-Maria; Tănase, Beatrice-Elena; Stoleru, Vasile
Cabbage is one of the most important vegetable crops in the world for its resilience. Cabbage crops require soils with a pH between 6 and 7.5. If necessary, amendments are used to correct soil acidity. Organic and inorganic fertilizers provide nutrients available to cabbage plants for proper vegetative growth. It has been found that nitrates accumulate predominantly in the outer leaves rather than in the head. The method of obtaining the biostimulant has different effects on nitrate content. Thus, in most cases, biostimulants obtained through mechanical homogenization decreased the nitrate content in the leaves but increased the nitrate content in the head; biostimulants obtained using ultrasound had the opposite effect, namely increasing nitrate content in the leaves but decreasing it in the head. The results obtained regarding the influence of herbal biostimulants on the content of microelements and macroelements will be presented.

The influence of soil management systems of the interval between vine rows on the penetration resistance of soils from Cotnari vineyard
(Editura ”Ion Ionescu de la Brad” Iasi, 2024) Alexandru, Mihai; Țopa, Denis-Constantin; Filipov, Feodor; Calistru, Anca-Elena; Jităreanu, Gerard
Soil is not only the physical support but also the main reserve of nutrients and water for the vines, which, together with meteorological factors and the level of agricultural techniques used, determine the quantity and quality of grape production. Vineyard mechanisation technology is the totality of all production processes, agricultural works, and operations carried out in a certain sequence, in optimal conditions and in compliance with agricultural technical requirements. The volume of work and the order in which it is carried out constitute the tillage system. The tillage systems used in vine plantations influence the physico-mechanical properties of the soil by using different systems of machinery and equipment during the course of a vineyard year. The studies were carried out on the western slope of Bejeneasa Farm, Cotnari Vineyard, in the Moldavian Hills Wine Region. The studied area is 0.31 ha. It is located in the upper part of the slope with a western exposure, and the slope of the land is <5%. The altitude is 170 m, and the mean annual precipitation and mean annual temperature values are 508.9 mm and 10.9℃, respectively. In order to highlight the effects of tillage systems in the plot cultivated with vines on the land with 8% slope and western exposure, three tillage systems were practised: a tillage system with a tiller, a tillage system with ridging, and a tillage system with a cultivator. For each tillage system, determinations were made on both the tractor wheel tracks and the mechanical spacing between the vine rows. Penetration resistance was determined using a penetrologger to a depth of 80 cm. The analytical data obtained showed that the penetration resistance of soils was influenced by the tillage system used. The range of variation of the values of penetration resistance for the wheel tracks of agricultural equipment was higher compared to those recorded on the vine rows.

(Editura ”Ion Ionescu de la Brad” Iasi, 2024) Russu, Stanislav; Balan, Valerian; Bîlici, Inna
This work is a comparative analysis of the mechanized contour pruning of sweet cherry trees carried out after fruit harvesting in an intensive cultivation system in the northern zone of the Republic of Moldova (47.9163o; 27.4587o; 160 m.) The orchard of sweet cherry trees with slender spindle-shaped crowns of the Sweet Stephany variety, grafted on the Gisela 6 rootstock and planted at a distance of 4x1 m, was established in 2018. The method and degree of contour pruning during the vegetation period of the trees was studied. The fruit quality can be improved using contour pruning without affecting the crop yield. The weight of the fruit (10.92-11.19 g), in the groups where mechanized contour pruning was used, was significantly greater than the weight of the fruit grown using annual maintenance and fruiting pruning (10.75 g). Regardless of the technique and degree of pruning, the Sweet Stephany variety has produced more than 80% of fruit larger than 26 mm in diameter.
