RIULS

Repository of Iasi University of Life Sciences, ROMANIA

Welcome to RIULS!

The mission of the University’s institutional repository is to manage, preserve and disseminate, in open access, the academic and institutional output of the university’s academic community. It also aims to promote values and personalities belonging to Romanian agricultural science, by storing digitized versions of rare books and manuscripts from its collections.

The repository is part of the international movement known as open science, which promotes free access to scientific literature. This translates into maximized impact of the work carried out by researchers, contribution to improving access to knowledge, increased visibility of the institution through the works of its authors and improvement of its search engine ranking.

All documents deposited in the repository receive a unique and persistent identifier called a Handle, thus guaranteeing perpetual access to scientific output through permanent links.

RIULS Repository of Iași University of Life Sciences is indexed in Duraspace, OpenDOAR,CORE,Google Scholar,BASE (Bielefeld Academic Search Engine) and ROAR (Registry of Open Access Repositories), global Directories of Open Access Repositories.

Learning resilience from resurrection plants – a botanical, literary and psychological approach to poems from american, australian and german literature
(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2025) Pelin, Raluca Ștefania; Slabu, Cristina
The concept of resilience is constantly making the headlines with regard to every aspect of life spanning from the environmental and economic areas to the fundamentally social and personal spheres of our existence. It becomes even more striking when it is represented by plants, the Resurrection plants, and becomes the core muse for poetry – the public artistic manifestation of the inner workings of the hearts and minds of people pondering on relationships and life issues. The present study aims at pinpointing the essential traits of these plants from the botanical perspective, reflected in several American, Australian and German poems and echoing in the much desired emotional intelligence competences that people need to acquire nowadays. The conclusion that can be drawn is that the environment plays a crucial role both in ensuring the survival conditions of plants and humans as well as in facilitating the acquisition of essential adaptive mechanisms and the mastery of resilience which culminates in the preservation of life and hope.

The influence of planting distance and crown shape on the growth and productivity of cherry orchards
(Editura “Ion Ionescu de la Brad” Iași, 2025) Balan, Valerian; Bîlici, Inna; Șarban, Vasile; Ivanov, Igor
Cherry cropping systems represent a topic of major interest in both scientific literature and fruit-growing practice. The aim of this study, conducted between 2013 and 2024, was to evaluate the impact of crown shape and planting distance on the growth and productivity of sweet cherry varieties grafted on the Gisela 6 rootstock. Within the research, the varieties Bigarreau Burlat, Ferrovia, and Lapins, evaluated in the 4th–7th years of vegetation, trained as Thin Spindle (TS) and planted at a distance of 5 × 1.5 m, demonstrated superior productivity. Likewise, the varieties Adriana, Ferrovia, and Skeena, planted at a distance of 4 × 2 m, recorded a superior yield throughout the bearing years when using the TS crown shape as well. Compared to the "Vase" and "Kym Green Bush" (KGB) training systems, the TS crown shape consistently provided the highest yields for the Samba, Early Star, and Black Star varieties planted at 4 × 2 m. Overall, the TS crown shape was associated with the highest yields across the entire analyzed fruiting period. It is worth noting that the productivity of early varieties was reduced in certain years due to unfavorable weather conditions during the critical stages of flowering, fertilization, and fruit set.

The impact of annual stem density on vegetative growth and fruiting in the raspberry variety Enrosadira
(Editura “Ion Ionescu de la Brad” Iași, 2025) Dodica, Dmitri; Balan, Valerian; Bîlici, Inna
Field study conducted in open ground to determine how growth and fruiting vary at five levels of annual stem density and to identify the optimal density level for the raspberry variety Enrosadira. Plants were planted at a distance of 2.5 m × 0.45 m. The density of annual stems varied between 12 and 20 plants per linear meter, on a strip 0.5 meters wide, spaced approximately 20–30 cm apart. Stem density was studied per linear meter in randomized blocks with replication: V1 – 12 stems, V2 – 14 stems, V3 – 16 stems, V4 – 18 stems (control), and V5 – 20 stems. Plant height, stem thickness, yield per stem and per hectare, fruit size, sugar/acidity content, and timing of fruiting were evaluated. Yield per stem and per hectare differed significantly between densities. The highest productivity was recorded in the variant with 14 stems per linear meter, without affecting fruit quality. At densities of 12–14 stems per linear meter, a delay in fruiting by 9 days was observed compared to those with a number greater than 16 stems per linear meter. Density above this level led to a reduction in the fruiting period and a decrease in fruit quality.

X-ray dose effects on seeds germination and seedling performance of european beech
(“Ion Ionescu de la Brad” University of Life Sciences, Iaşi, 2025) Elisovetcaia, Dina; Ivanova, Raisa; Andronic, Larisa
The aim of the study was to assess germination dynamics and post-germination adaptation in two populations of European beech (Fagus sylvatica L.) seeds collected in autumn 2023 in the 'Plaiul Fagului' State Nature Reserve, Republic of Moldova with contrasting initial viability levels (PF-23high – 97% and PF-23low – 57%) under X-ray exposure at doses ranging from 25 to 300 Gy. Germination parameters, including total germination, mean daily germination (MDG), mean germination time (MGT), and germination rate index (GRI), were recorded alongside seedling development under solarium conditions. PF-23high exhibited a more enhanced response: exposure to 25–125 Gy stimulated earlier and more intense germination (MDG up to 1.55; GRI up to 2.00), with a peak germination of 77.33% at 125 Gy and a 21-day advancement relative to the control. In contrast, PF-23low showed only moderate stimulation at 25 Gy (germination 65.67%, 13 days earlier than control), and was markedly more sensitive to doses ≥100 Gy, with reduced germination and delayed dynamics (MGT up to 122 days; MDG and GRI consistently lower across treatments). At high doses (200–300 Gy) both populations demonstrated a pronounced decline in germination parameters. Seedling survival under solarium conditions revealed a uniformly negative impact of irradiation: both PF-23low and PF-23high showed rapid post-germination mortality, particularly between weeks 6 and 10 at doses ≥50 Gy. Despite the initially higher physiological resilience of PF-23high, neither population exhibited stable adaptation under prolonged post irradiation stress. These findings may suggest a high level of radiosensitivity in European beech during early ontogenetic development, regardless of initial seed viability.

Evaluation of apple varieties for industrialization in an intensive system
(Editura “Ion Ionescu de la Brad” Iași, 2025) Plămădeală, Ivan; Bîlici, Inna; Balan, Valerian
Purpose: Evaluation of the agrobiological and technological performance of ten apple cultivars grafted on M9 rootstock in southeastern Republic of Moldova to identify optimal varieties for industrial processing. Material and Methods: In 2025, at a density of 2,083 trees/ha (4 × 1.2 m), cultivars 'Champion', 'Florina', 'Gloster', 'Golden Delicious', 'Idared', 'Mutsu', 'Pinova', 'Renet Simirenco', 'Golden Rezistent', and 'Granny Smith' were evaluated. Yield parameters (kg/tree, t/ha), average fruit mass (g), firmness (kgf/cm²), titratable acidity (%), soluble solids content (°Brix), and pH were determined. Results: Yield ranged from 9.91 t/ha ('Mutsu') to 39.33 t/ha ('Golden Rezistent' – 18.88 kg/tree), followed by 'Idared' (32.76 t/ha). Average fruit weight varied between 126.1 g ('Pinova') and 164.2 g ('Mutsu'). Highest firmness was recorded in 'Gloster' (12.3 kgf/cm²). Soluble solids content ranged from 14.2 °Brix ('Mutsu') to 16.2 °Brix ('Champion'). Maximum titratable acidity was found in 'Renet Simirenco' (1.01%), 'Granny Smith' (1.01%), and 'Idared' (0.91%). Conclusions: Cultivars 'Renet Simirenco', 'Granny Smith', and 'Idared' are optimal for juice production due to high firmness and acidity, while 'Golden Rezistent' and 'Champion' offer superior yields for concentrate production
