The investigated traits exhibited notable variability. Noteworthy variations were observed in the weight of 100 seeds, ranging from 346 to 800 g, seed length spanning 4–2.5 cm, and seed diameter varying between 1.92 and 1.41 cm. Germination percentages ranged from 73.6 to 46%, while survival percentages showed a range of 88.6–71%. Regarding growth parameters, the study documented seedling height and seedling basal diameter. Seedling height ranged from 12.25 to 12 cm, while seedling basal diameter varied from 5.12 to 2.3 cm. All evaluated characteristics exhibited significant heritability, with survival percentage demonstrating the highest heritability at 89.54%, and seed diameters displaying the lowest at 67.74%. Furthermore, substantial phenotypic coefficient of variability was observed, indicating substantial diversity within the studied germplasms. This variability underscores a valuable opportunities for meticulous screening and selection of optimal seed sources. The findings of this study contribute to comprehensive understanding of Mahua germplasms and their potential applications.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 4","pages":"684 - 691"},"PeriodicalIF":1.4,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141687296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A split-plot experiment was conducted using a randomized complete block design (RCBD) with three replications for two crop years (2018–2020) at the Sistan Agricultural and Natural Resources Research and Education Center, Iran. The irrigation methods included: I₁, which involved irrigation during vegetative, flowering, and seed-filling stages; I₂, which involved irrigation during vegetative and flowering stages; I₃, which involved irrigation during flowering and seed-filling stages; I₄, which involved irrigation only during flowering stage; and I₅, which involved no irrigation at all. The experiment also included testing plant density at 30, 50, and 100 plants per m². The study found that different irrigation regimes significantly impacted seed yield, relative water content, chlorophyll, proline, total carbohydrate, antioxidant activities, and essential oil content. The maximum seed yield was attained with I₁ (control) and a planting density of 100 plants per m², resulting in 651.9 kg ha⁻¹ and 672.4 kg ha⁻¹ in the first and second years, respectively. The irrigation during flowering and seed filling (I₃) with 50 and 100 plants per m² also showed a high seed yield in the first year. Non-irrigation and 30 plants per m² density resulted in the highest catalase, peroxidase, and superoxide dismutase activities. The essential oil content varied depending on irrigation and planting density, with the highest content achieved with I₄ irrigation and a planting density of 50 and 30 plants per m² in the first and second years (5.44 and 4.5%), respectively. The essential oil compounds with the highest mean values were β-pinene and safranal, while cuminaldehyde and sabinene had the lowest mean values. The research findings suggest that for optimal plant performances, it is advisable to use a planting density of 50 plants per m² and implement two irrigation stages during vegetative growth and flowering.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 4","pages":"660 - 675"},"PeriodicalIF":1.4,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is because harvesting seeds at the right time is critical to assure their viability and vigor. The use of nonlinear regression models could estimate the accurate time of PM and SQ in camelina at all plant densities based on days after flowering (DAF) and/or seed moisture content (SMC). To attain this goal, camelina seeds were sown manually at a 2–3 cm burial depth with four plant densities (150, 600, 1050, and 1500 m⁻² with ± 5% bias) in eight replicates. Seeds were sampled from 10 DAF at regular intervals every 5 or 10 days (depending on the weather conditions) for all plant densities. We examined the changes in fresh weight, dry weight, moisture content, oil content, and electrical conductivity of seeds. We also studied seed germination rate, normal seedling, and dry weight and length of seedlings about the flowering date across different plant densities. Our results were successful in accurately predicting the timing PM and SQ in camelina across all plant densities using DAF and/or SMC (<i>R</i>² ≥ 80) as a basis. Besides, no significant difference among all studied plant densities in terms of the studied traits was detected. These findings enable the fine-tuning of agronomic practices, such as determining the optimal harvest period.

This study investigates the impact of frequency-dependent pre-sowing magneto-priming treatment on anise seed (<i>Pimpinella anisum L</i>) productivity. During the seasons of 2021/2022 and 2022/2023, anise seeds were exposed to DC, 5 Hz, and 10 Hz magnetic field treatments for different durations (20, 40, 60, and 80 min) prior to sowing. The growth parameters of the plants, fruit yield, and essential oil content were evaluated for both the magnetically treated and untreated seeds. The results indicate that the productivity of anise seeds is influenced by the frequency and duration of the magnetic field treatment. Among the different treatments, seeds treated with a 10 Hz frequency for 40 min exhibited the highest vegetative growth parameters, fruit yield, and oil yield compared to the untreated seeds.

It impacts various growth stages, including seed germination, vegetative growth, reproductive development and crop maturity. Among these stages, seed germination is particularly sensitive. In this study, we aimed to assess the effect of water deficit by manipulating the water potential of the germination medium [0, − 1, − 1.5 and − 2 MPa (Megapascal)]. Our results revealed that a decrease in the osmotic potential influenced all seedling parameters. Specifically, we observed variations in the activity of amylase, an enzyme involved in starch breakdown during germination. The timing of amylase activity depended on both the germination duration and the severity of water deficit. After 24 h, amylase activity increased due to reduced water potential, but it reached its peak after 48 h and subsequently decreased significantly under water stress. This enzymatic activity led to the accumulation of simple sugars in germinating seeds. Interestingly, our study also revealed intraspecific variability in the response to water stress. Specifically, seeds from the Chen’s and Simeto genotypes exhibited higher accumulation of soluble sugars compared to other genotypes, indicating their greater tolerance to water deficit. Considering this, integrating these tolerant genotypes into genetic improvement programs could enhance durum wheat resilience to water scarcity. Understanding the impact of water deficit on seed germination and seedling development is crucial for developing strategies to mitigate its effects and improve crop productivity in water-limited environments.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 4","pages":"676 - 683"},"PeriodicalIF":1.4,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141364034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low molecular weight nucleoredoxin (NRX) is a nuclear thioredoxin (TRX) system with oxidoreductase capacity which can protect the cellular components like DNA, RNA or protein by protecting antioxidative enzymes like catalases. In response to the adverse environmental conditions, plant cells generate more ROS as a result of signal-led cellular defense mechanism.
