Dinamica adsorbţiei Sr2+ din soluţii apoase pe cărbunele activ CAN-7 [Articol]
(Universitatea de Stat din Moldova, 2021) Lupașcu, Tudor; Ciobanu, Mihai
S-a studiat dinamica adsorbţiei ionilor de stronţiu din soluţii apoase pe cărbunele activ CAN-7 concentrat la diferite lungimi ale stratului de lucru al coloanei cu adsorbant şi la diferite viteze de filtrare a soluţiei. În baza curbelor de străpungere a ionilor de stronţiu din soluţii apoase pe cărbunele activ CAN-7 la viteza de filtrare a soluţiei 10 mL/min, s-a determinat: lungimea stratului de lucru al coloanei cu adsorbant, lungimea stratului inactiv, viteza de mişcare a frontului adsorbţional şi timpul de parcurs al soluţiei cu adsorbat prin stratul de lucru al adsorbantului.
Noi derivați vinil-triazolici cu activitate antimicrobiană în condiții in vitro [Articol]
(Academia de Ştiinţe a Moldovei, 2025) Lupașcu, Galina; Cristea, Nicolae; Lupașcu, Lucian; Stîngaci, Eugenia; Ceabanova (Zveaghinţeva), Marina; Pogrebnoi, Serghei; Macaev, Fliur
The diseases of various plants, caused by fungi and bacteria, are bringing serious economic damage to many countries and health problems for all living organisms. The chemical plant protection measures are often ineffective due the pathogens’ ability to easily adapt to pesticides, as well as to the reduction of their effectiveness under the influence of unfavorable conditions, especially drought. The study of antifungal (Fusarium culmorum) and antibacterial (Bacillus subtilis, Pseudomonas fluorescens, Erwinia carotovora, E. amylovora, Xanthomonas campestris) activities of the new vinyl-triazole derivatives (VTDs) demonstrated their high effectiveness at relatively low concentrations (0.00125 ... 0.02%) against F. culmorum isolates, and 0.0025 ... 0.011% in the bacterial cases, which provides opportunities for the using of VTD in the plant protection strategies.
Utilizarea indicelui de vulnerabilitate climatică pentru sectorul agricol din Republica Moldova [Articol]
(Academia de Ştiinţe a Moldovei, 2025) Druță, Ala; Rudi, Tamara; Smerea, Svetlana; Andronic, Larisa
The article analyses the vulnerability of the agricultural sector in the Republic of Moldova to climate change by constructing and applying a composite Climate Vulnerability Index (CVI), based on a triadic assessment: exposure, sensitivity, and adaptive capacity. Covering the period 2012–2021, the study employs 64 indicators distributed across thematic and spatial subcomponents, analysing disparities among the three agroecological zones (North, Center, and South). The results reveal increased vulnerability in the AEZ South, driven by frequent climatic variability and extreme events, while AEZ Center exhibits heightened agricultural sensitivity in crop production. Adaptive capacity has improved in the AEZ Center due to agro-technological development and crop diversification, and in the AEZ North mainly due to subsidies and insurance policies. The decreasing values of the index over the analyzed period reflect a strengthening of agricultural system’s resilience and position the CVI as a strategic tool for guiding adaptation policies, prioritizing investments, and monitoring progress in reducing climate risks and vulnerabilities.
Influența mutagenezei induse asupra unor parametri ai productivității în generațiile M2 și M3 la susan (Sesamum indicum L.) [Articol]
(Universitatea de Stat din Moldova, 2021) Mogîlda, Anatolii
Creșterea mutației la plantele de cultură este o abordare eficientă în îmbunătățirea culturilor cu o bază genetică îngustă, cum ar fi susanul. Scopul de bază al acestui studiu este de a determina efectul mutagenezei induse asupra unor parametri ai productivității la mostra Kadet (200 – 500 Gy) în generațiile M2 și M3. La prelucrarea statistică a datelor s-a constatat: în M2 – toate dozele (200 – 500 Gy) sunt considerate a fi mai productive comparativ cu controlul, iar în M3 – dozele de 300 Gy și 500 Gy au înregistrat valori mai mari comparativ cu controlul Kadet. De asemenea, mostra Kadet cu doza de 500 Gy după parametrul productivitatea per plantă a fost determinat de o corelare puternică cu numărul de capsule per plantă și cu numărul de semințe per capsulă, iar la doza de 300 Gy acești parametri au avut o corelare medie.
Molecular diagnostics of soil-borne pathogenic fungi in several agricultural crops [Articol]
(Universitatea Tehnică a Moldovei, 2025) Diaghileva, Angela
Modern requirements for product quality provide for expanding the competence in sectors of producing and managing agricultural products by investigating the cause-effect relationships in the transmission of diseases between species through host-pathogen interactions. Monitoring and accurate identification of pathogens in agriculture products are essential for successful implementation of an integrated pest management program. Among the pathogens that have a serious impact on agricultural production, micromycetes outnumber all other species. Diagnostics of fungal pathogens using traditional methods can be difficult due to the similarity of their morphological traits, the lack of the ability to study non-culturable genotypes. In this regard, molecular detection methods based on polymerase chain reaction (PCR) were used in the study, which allow specific detection of any microorganisms. Analysis of the species composition of pathogenic fungi of Fusarium, Penicillium and Aspergillus genera in the genotypes of some vegetable crops of local selection was conducted based PCR-assay. The efficiency of molecular technique for the speciesspecific detection of pathogenic fungi that can affect agricultural crops was demonstrated. Molecular diagnostic assessment of the phytosanitary status of seeds of different storage periods was done. Development of some fungal infection during plant ontogenesis using nested-PCR assay was monitored.
