Evaluation of Walnut (Juglans regia L.) Grafting Performance by Optimizing Methods and Execution Periods Using TOPSIS Multicriteria Analysis
(MDPI, 2026-06-17) Zlati, Cristina; Pașcu, Roxana; Florea, Marius; Dascălu, Marius; Pătrașcu Sonea, Andromeda-Cristina; Istrate, Mihai
Walnut multiplication technology for obtaining high-quality planting material consists of grafting, followed by forcing bionts in protected spaces under controlled microclimatic conditions, and completed by acclimatization under field conditions. The present research substantiates the hypothesis that the use of protected spaces (polyethylene tunnels) enables rigorous control of limiting factors. The main objectives of the paper are the comparative evaluation of two grafting methods (chip and patch budding) on the grafting success of eight native genotypes (‘Anica’, ‘Grădinar’, ‘Miroslava’, and ‘Velnița’, ‘Bălțăți’, ‘Belcești’, ‘Săbăuani’, and ‘Șorogari’) grafted on ‘Bălțați’ local biotype, determining the optimal moment of grafting by identifying the time window (April vs. August) that maximizes the success rate of the grafting association. The study, carried out from 2022 to 2024, evaluated the performance of chip and patch budding executed under high-tunnel conditions, quantifying the scion/rootstock growth, callus formation, and anatomical symbiont similarity through cross-sectional microscopy and image analysis software to measure vessel number, density, and diameter; the results are presented as the mean values of three annual repetitions across the experimental period. Preliminary results indicate a superior efficiency of the chip budding method, with a 51.3% success rate compared to 32.9% for the patch budding method. Another objective of the study was the ranking of the experimental variants. Thus, the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), a multi-criteria decision analysis method, ranked the experimental variants and identified the chip budding performed in April (variant a1/b2) as the optimal solution across all analyzed physiological and morphological parameters. These findings are highly significant for the nursery sector, as they demonstrate that transitioning from unpredictable field conditions to controlled high-tunnel conditions stabilizes production outcomes. By establishing a clear methodological hierarchy and a precise chronological window, this study provides actionable guidelines to standardize walnut multiplication, mitigate seasonal climate risks, and substantially increase the output of high-quality certified planting material.

Sustainable Cellulose-Based Gels: Synthesis, Chemical Modification, and Biomedical Application
(MDPI, 2026-07-20) Tofănică, Bogdan-Marian; Ungureanu, Elena
The growing demand for sustainable, biocompatible, and non-toxic biomaterials has driven significant advancements in biobased gels for biomedical applications. Among these, cellulose—the most abundant renewable biopolymer—presents an ideal platform due to its inherent hydrophilicity, structural tunability, and biodegradability. This review reports the recent advancements in the processing and engineering of cellulose-based hydrogels for drug delivery systems. We systematically explore the primary synthesis routes, including physical, chemical, and hybrid cross-linking strategies. Special emphasis is placed on chemical modifications (e.g., sulfation, carboxylation, etherification, and polymer grafting) that allow precise tuning of the gel’s mechanical strength, swelling kinetics, and stimuli-responsiveness (such as pH, temperature, or enzyme sensitivity). Furthermore, the review highlights essential characterization techniques—spanning structural, morphological, and rheological evaluations—used to relate cross-link density to the water-holding capacity and network homogeneity. By leveraging their highly hydrated and porous 3D architectures, these modified cellulosic networks demonstrate exceptional efficiency in drug loading, controlled release, and targeted localized therapy. Finally, we discuss current challenges, including industrial scalability and mechanical stability, and provide future perspectives on integrating nanoparticles and bioactive moieties to develop “smart” drug-eluting matrices and wound care dressings. Ultimately, this review underscores the immense potential of cellulose-based gels in advancing both clinical outcomes and circular economy goals.

Bioremediation of Heavy Metal-Contaminated Agricultural Soils: Mechanisms, Emerging Technologies, and Pathways to Field-Scale Application
(MDPI, 2026-05-30) Motrescu, Iuliana; Luchian, Camelia-Elena
Agricultural soils worldwide are facing escalating contamination by heavy metals, which present high risks for health due to their persistence, being non-biodegradable, accumulating across the soil profile, and being easily transferred into edible plant tissues, thus propagating through the food chain, with serious consequences for human health and ecosystem integrity. Conventional physical and chemical remediation approaches are costly, ecologically disruptive and operationally complex for the extent of contamination of agricultural land. Thus, there is an urgent need for sustainable and scalable alternatives. This review addresses the need by providing an integrated, mechanistically grounded synthesis of plant-based bioremediation strategies for heavy metal contamination removal, emphasizing the links between soil chemistry, plant physiology, and soil microbiology. First, the principal contamination pathways and controls on metal speciation and bioavailability are summarized, highlighting how parameters such as pH, organic matter, clay minerals, and redox conditions govern the metal fraction available for the plants. The molecular basis of plant heavy metal uptake, translocation and detoxification is examined in detail, including transporter-mediated root uptake, xylem loading and long-distance transport, and chelation by phytochelatins and metallothioneins. The performance and limitations of the main phytoremedation strategies are evaluated across representative hyperaccumulator species, then two major enhancement solutions are discussed: chemical enhancement using synthetic and biodegradable agents, and biological enhancement through plant growth-promoting rhizobacteria, arbuscular mycorrhizal fungi, and mycoremediation fungi. Integrating these perspectives, this review provides a critical assessment of when and how phytoremediation can offer a realistic and agronomically compatible route for managing heavy metal contamination in agricultural soils

Current Perspectives on the Sustainable Remediation of Lead-Contaminated Water Using Tomato Juice By-Products
(MDPI, 2026-04-07) Enache, Iuliana-Maria; Motrescu, Iuliana; Cara, Irina-Gabriela; Protea, Miruna-Paraschiva; Țopa, Denis-Constantin; Ungureanu, , Gabriela; Patraș, Antoanela
The large quantities of agri-food waste produced worldwide by the tomato processing industry require recovery. This study evaluated the efficiency of the by-product resulting from tomato juice preparation as an innovative biomaterial for removing lead from water. The pomace was dried and tested in two forms: raw (RT) and after extraction of soluble compounds (ET). The extracts obtained from the preparation of ET, could be reintroduced into the food industry (as colorants, etc.) according to the “zero waste” principle, but further studies are needed. No other chemical pre-treatment was applied to improve the lead-adsorption capacity. The pH influence, biosorbent dosage, kinetics and equilibrium were evaluated. Analytical methods, such as atomic absorption spectrometry, elemental chemical analysis, FTIR, scanning electron microscopy, and predictive models, were applied. The outcomes demonstrated a lead-adsorption efficiency of 99.22% for ET and 89.83% for RT, an optimum pH of 4.0 ± 0.5, and an initial solution containing 20 mg Pb2+/L. The Langmuir model predicted high removal capacities: 142.18 mg/g for ET and 90.91 mg/g for RT. Both forms of tomato pomace were efficient for sustainable and cost-effective water remediation, but an improvement was noticed after the extraction of soluble components that could be valorized in other products within the circular economy.

Allelopathic Interactions in Vegetable Production Systems: Current Knowledge and Future Perspectives
(MDPI, 2026-04-02) Tănase, Beatrice-Elena; Istrate, Ana-Maria-Roxana; Stoleru, Vasile
The need to investigate ecological and sustainable approaches to weed management, as well as to reduce the negative environmental impact of chemical herbicides, is becoming increasingly important in modern agriculture and land management. Among alternative strategies, allelopathy is a natural mechanism by which particular plant species release bioactive compounds that can influence the germination, growth, and development of neighboring plants. Harnessing allelopathic interactions offers an opportunity to develop environmentally friendly alternatives to synthetic herbicides and helps preserve ecological balance within agroecosystems. This review examines the potential of allelopathic plant-derived substances for weed control in agricultural systems, with particular emphasis on managing weed populations in vegetable crops and gardens in urban and peri-urban areas. This study introduces the concept of allelopathy with definitions and general information. Subsequently, the paper analyzes the phenomenon’s presence at the plant level, its interactions, and the extracts obtained from allelopathic plants. The paper focuses on essential oils and fatty acid-derived compounds, such as pelargonic acid, which have demonstrated significant inhibitory effects on weed germination and biomass accumulation. Overall, the presented results establish a scientific basis for developing bioherbicides and support implementing sustainable, environmentally responsible horticultural practices.
