During dormancy release following H₂SO₄-MTW-GA₃ treatment, consistent with the observed metabolic enzyme activities, the contents of protein and fat showed a downward–upward–downward trend, whereas the sugar and starch contents showed an upward–downward trend. Hence, the H₂SO₄-MTW-GA₃ treatment enhanced the conversion of glycogen, starch, protein, and fat to nutrients and energy, while also increasing the activities of diverse metabolic enzymes. Furthermore, the abundance of different hormones promoting seed dormancy release peaked at different time points. Specifically, the GA content peaked before the trans-zeatin-riboside (ZR) content, which may be related to the different mechanisms by which various hormones induce dormancy release.</div></div>","PeriodicalId":15136,"journal":{"name":"Journal of Applied Research on Medicinal and Aromatic Plants","volume":"45 ","pages":"Article 100625"},"PeriodicalIF":3.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, a comprehensive ecological study of AMF in black pepper (<em>Piper nigrum</em> L.) fields was conducted. The study aimed to identify AMF diversity and population characteristics over a broad area of black pepper fields in Kerala, South India, and to analyse various factors influencing AMF symbiosis in crops. It also focused on identifying the agroclimatic, soil, and crop influencers that impact mycorrhizae in traditional crop fields. Altogether, nine genera and 29 AMF species are identified from the randomly sampled black pepper fields (of diverse varieties of the crop) that belong to two different soil orders and 13 different soil series in the region. Among them, three genera and 22 species were new reports from black pepper. <em>Acaulospora laevis</em> and <em>Funneliformis badius</em> were the most commonly found species. Seasonal analysis showed a significant increase in spore density during the monsoon season, while root colonization exhibited varying patterns.

Each parameter of the EP-MHD method was optimized through the sequential optimization approach. Subsequently, the optimized EP-MHD method was compared with the hydrodistillation (HD) method and the microwave-assisted hydrodistillation (MHD) method in terms of both the yield and chemical composition of essential oil. The essential oil yield from the EP-MHD method (2.19 ± 0.07 mg/g) was significantly higher compared to both the MHD method (1.62 ± 0.05 mg/g) and the HD method (1.39 ± 0.09 mg/g), showing increases by 1.35 and 1.58 times, respectively. The results of GC/MS analysis showed that the main components of the essential oil were alcohols, aldehydes, and terpenoids, including isopimarinal, sandaracopimaral, sandaracopimarinol, 5,8,11-heptadecatrien-1-ol, pentadecanal, 2,4-di-tert-butylphenol, β-(<em>Z</em>)-curcumen-12-ol, and spatulenol. Particularly, the essential oil obtained by EP-MHD method had the highest alcohol components content (45.61 %), which significantly higher than those obtained by the MHD (25.17 %) and HD methods (23.95 %). Moreover, the essential oil extracted by the EP-MHD method exhibited superior scavenging ability against DPPH and ABTS⁺ radicals (with IC₅₀ values of 1.14 and 1.03 mg/mL, respectively). Additionally, it demonstrated antidepressant activity with IC₅₀ values of 3.77 mg/mL and 4.46 mg/mL against acetylcholinesterase and butyrylcholinesterase, respectively, which surpassed those obtained from the HD and MHD methods. Furthermore, the essential oil obtained through EP-MHD displayed notably stronger antibacterial activity against <em>Escherichia coli</em>, <em>Staphylococcus aureus</em>, and <em>Listeria monocytogenes</em> with IC₅₀ values of 1.70 mg/mL, 1.03 mg/mL, and 2.30 mg/mL, respectively.

Higher variability estimates for tillers per plant, number of leaves per stem, flower head length, flower head branches, biological yield per plant and essential oil content demonstrated their potential utilization as selection criteria for higher genetic gains. Based on mean performance, AMMI, WAAS, and genotype and genotype by environment analysis, genotypes G1, G2 and G4 were identified as the most stable with high trait performance and geraniol content.

In total, eight field trials were carried out in 2020 and 2021 at two experimental farms of the University Bonn in the west of Germany.

However, due to variable operating conditions a consistent ranking of weeding devices was not possible. We conclude that despite significant technical progress during the last two decades, a complete replacement of herbicides is difficult at present, unless weed control is carried out manually.

The objectives of the present work were to determine the optimal temperature for seed germination of an important medicinal species and evaluate the degree of tolerance to saline and thermal stresses during germination and early seedling stages of <em>Anabasis articulata</em>. Seeds were collected from individuals of two populations of <em>Anabasis articulata</em> located in Sed Rahal (Djelfa-Algeria) and Oued N’sa (Ouargla-Algeria). Seeds were germinated at seven salinity levels (0, 100, 200, 300, 400, 500, and 600 mM) and incubated at eight temperatures (5,10, 15, 20, 25, 30, 35, 40, and 45°C). The germination attributes studied were germination kinetics, germination percentage, germination rate, and the measurement of shoot and root lengths of seedlings. The statistical analysis revealed that salinity level and temperature variations significantly affected germination and post-germination characteristics. The highest germination percentages were obtained under non-saline conditions; salt stress delayed or limited the germination process and seedling growth. High temperatures (35–45°C) have a more negative effect than lower temperatures (5–15°C). Optimum temperatures range from 20 to 30°C. At these temperatures, even at a saline concentration of 600 mM, 46 % of the seeds were able to germinate for the Sed Rahal station and 21 % for the Oued N’sa station. Sed Rahal exhibited higher final germination percentages, germination rates, and seedling growth compared to Oued N’sa, particularly under moderate temperatures and lower salinity levels, demonstrating better resilience to salinity and temperature extremes. Sed Rahal seedlings exhibited more reduction in root length at low temperatures, while Oued N’sa seedlings showed more reduction in shoot length at high temperatures.
