This study evaluated the bioherbicidal potential of crude hydroalcoholic extracts of root and aerial parts of <i>Ferula persica</i> (FRE and FSE, respectively) for managing canary grass (<i>Phalaris minor</i> Retz.) in wheat (<i>Triticum aestivum</i> L.) systems. Extracts (0.25% and 0.5% w/v) were tested for their effects on germination, physiological traits, and competitive performance of both species under monoculture and co-culture conditions. Ferula extracts significantly reduced seed germination of both wheat and canary grass seeds. In monoculture conditions, the extracts increased shoot wheat and canary grass biomass. Under co-culture conditions, however, the combined stress of wheat competition and extract application significantly reduced biomass, soluble sugars, and secondary metabolites, including phenolics, flavonoids, and anthocyanins in canary grass, while in wheat caused greater physiological tolerance and, in some cases, enhanced secondary metabolism. Competitive indices confirmed strong asymmetric competition in favor of wheat: relative yield values for wheat were consistently above 1.0 (RYw = 1.09–1.71), whereas canary grass exhibited extremely low relative yields (RYp = 0.031–0.049). The competitive balance index (Cb = 3.10–4.01) consistently indicated wheat dominance across all treatments, and weed suppression exceeded 95% even at the lowest extract concentration (0.25%), without any reduction in crop relative yield. These findings demonstrate that <i>F. persica</i> extracts can suppress canary grass growth through a combination of allelopathic and competition-mediated mechanisms in wheat, supporting their potential development as natural bioherbicides for sustainable weed management in wheat production systems.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"50 6","pages":"2059 - 2069"},"PeriodicalIF":1.4,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine how EBP disrupts the viral envelope and the conditions under which virus destruction occurs most rapidly. These conditions are analyzed by considering the relevant cross-section for EBP–microparticle interactions within the orbit-limited motion (OLM) model and by applying Maxwellian and Tsallis distributions. The results indicate that both the physical characteristics of the EBP and the structural properties of the viruses directly affect the charging rate. Major parameters, including the initial conditions, non-extensive parameter, Young’s modulus, EBP flux, energy, and density, are identified as essential factors governing the charging process. This process, in turn, leads to the inactivation and destruction of viruses and other similar microorganisms. Therefore, the theoretical framework developed here supports the broad applicability of plasma technology in practical healthcare-related applications, particularly for environmental pollution control, decontamination and the treatment of viral diseases.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"50 6","pages":"2339 - 2352"},"PeriodicalIF":1.4,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The search region is modeled as a spherical domain centered at the origin and partitioned into N symmetric spherical sectors, each assigned to a search agent. Within its sector, each agent performs an expanding radial search combined with systematic scanning of spherical surfaces. Using spherical coordinates and a probabilistic decomposition of the domain into successive spherical shells, an analytical expression for the expected detection time is derived. The optimal search strategy is obtained by minimizing the expected detection time with respect to the sequence of expansion radii. For the case of a spherical normal distribution, explicit probabilistic expressions are obtained and recursive relations are established that characterize the optimal radii ensuring monotone spatial coverage. The analytical formulation further allows asymptotic analysis with respect to the number of searchers, showing that the expected detection time decreases as the number of coordinated agents increases. Numerical experiments illustrate the theoretical results and highlight the influence of key parameters on search efficiency. The proposed framework extends coordinated sector-based search models from planar environments to three-dimensional domains and provides a scalable mathematical basis for multi-agent search operations under spatial uncertainty.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"50 6","pages":"2239 - 2250"},"PeriodicalIF":1.4,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shoot-tip explants were exposed to different EMS concentrations and exposure durations, and regenerated plantlets were analyzed to evaluate molecular polymorphism. Out of 24 ISSR primers screened, 11 produced clear and reproducible polymorphic banding patterns. ISSR analysis revealed differences in band profiles among cultivars and treatment combinations, indicating treatment- and genotype-associated genetic variation. The highest polymorphism level was observed in the Agria cultivar, while lower levels were recorded in Marfona and Lady Olympia. Cluster analysis (UPGMA) and principal component analysis (PCA) showed partial grouping of samples according to genetic similarity, with some EMS-treated individuals displaying divergence from control samples. Analysis of Molecular Variance (AMOVA) indicated that most genetic variation was distributed within cultivars, while a smaller proportion was attributed to differences among cultivars. Overall polymorphism was slightly higher in EMS-treated samples compared with controls, suggesting that EMS treatment may contribute to detectable molecular variation under in vitro conditions. However, ISSR markers detect dominant banding patterns and do not directly confirm specific mutation events. Therefore, the observed variation should be interpreted as EMS-associated genetic diversity rather than confirmed EMS-induced mutations. These findings demonstrate that ISSR markers can be effectively used as a preliminary tool to assess genetic variation induced under mutagenic conditions in potato breeding materials.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"50 6","pages":"2047 - 2058"},"PeriodicalIF":1.4,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
