This research aimed to conduct phytochemical screening; assess of antimicrobial and antioxidant activities; evaluate toxicity and detect the nutritional value of Hibiscus sabdariffa L. seeds. The Phytochemical screening was carried out using standard procedures. The samples were extracted using hexane and absolute ethanol respectively. The extracts were evaluated for their effectiveness against microorganisms using the disc diffusion method and the antioxidant potential was measured by the DPPH assay. The proximate analysis of seed powder and mineral composition was determined using standard procedures. Toxicity was evaluated by the brine shrimp lethality test and the LD50 was calculated. Phytochemical screening revealed the presence of alkaloids, saponins and flavonoids, while tannins and anthraquinones were not detected. Generally, the hexane extract showed higher antibacterial activity than the ethanolic extract against 4 bacteria. Both extracts exhibited antifungal activity against Candida albicans ranging from 12-17 mm. The hexane extract showed higher antioxidant activity than the ethanolic extract (60 % and 47 % respectively). Both extracts were non-toxic against brine shrimps, suggesting that they are safe for medicinal use. The results of the proximate analysis showed that the seeds contain high amounts of fat (34.19 %) and protein (33.25 %). The seeds of H. sabdariffa contained considerable amounts of some important elements, while lead was not detected. The findings of this study revealed that H. sabdariffa seeds are a rich source of secondary metabolites and nutritional value and could be used for pharmaceutical preparation and drug development.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":" January","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141824071","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}

Curcuma genus related to the family Zingiberaceae comprises a significant number of medicinal plants renowned for their use in ethnomedicine, playing a pivotal role in the medical, health, and pharmaceutical sectors. Traditionally, morphological methods alone have proven insufficient for accurately identifying species within this family. However, DNA barcoding technology provides a contemporary solution by utilizing plant DNA sequences for species identification, thus enabling effective conservation efforts. We used DNA barcoding techniques and for analysis used the Maximum Parsimony tree in MEGA 11 with the Kimura 2-parameter (KP model) to analyse the genetic relationships between species. Out of the 13 accessions that were studied, 12 accessions belonged to Curcuma caesia and 1 accession belonged to Curcuma aeruginosa. The genetic relationships observed were correlated with the geographical distributions of these species. It was determined that C. aeruginosa is a mutated species of C. caesia. Additionally, 1 specimen of Alpinia galanga, a plant species related to the Zingiberaceae. Barcode primer trnL primer demonstrated a 92% efficiency during the investigation. The rbcL and trnL loci are recommended as potential barcode markers for discriminating between different plant species. This study developed a comprehensive DNA barcoding database that can confidently differentiate between species by combining morphological and molecular data. This database has the potential to identify adulteration in herbal products, combat illegal trade and adulteration of plant species, and assist in germplasm conservation efforts.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":" 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141830144","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 study aimed to explore the dynamics of Fe deficiency in oil palm leaves in Central Kalimantan, Indonesia. Using a Split Plot Design, the study compared plant conditions between the control (T0) and three levels of Fe deficiency: low (T1), moderate (T2), and severe (T3). Palm samples were selected using the purposive sampling method. Laboratory analysis of leaf samples indicated a significant decrease in Fe content in deficient palms, with levels of 41.49 µg/g in T1, 42.59 µg/g in T2, and 38.93 µg/g in T3, compared to the control group, which had 67.25 µg/g. The study also revealed that Fe deficiency affects the absorption of other macro and micronutrients. For instance, nitrogen levels increased under moderate Fe deficiency (2.57%), while potassium levels decreased (0.729%) at the same level. Despite the Fe deficiency, the plants adapted by maintaining other nutrient levels within a moderate range. Under severe Fe deficiency conditions, Cu levels reached their highest (5.868 µg/g), while Fe showed a significant decrease. This confirms that oil palm has complex nutrient adaptation and regulation mechanisms to maintain nutrient balance even under deficient conditions. These results emphasize the importance of Fe management in oil palm plantations, especially in sandy soils that are prone to nutrient deficiency.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141830378","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}

To encounter this problem, modern, environmentally friendly technologies must be used, including amino acids such as arginine, which help in improving growth and yield and thus increase the productivity of this crop quantitatively and qualitatively per unit area. An experiment was conducted in a field in the Saqlawiyah-Anbar region in 2021 during the winter season, to look into how different arginine concentrations affect specific growth traits and yield of different wheat varieties. Randomized complete block design was utilized in the split plot arrangement with three replications, main plots had two concentrations of arginine (100,200 mg l-1), while subplots contained three varieties of wheat (Abu Gharib, Sham 6, and Ebaa 99). The study's findings demonstrated the superiority of the variety Ebaa 99 in most growth traits and yield, including the flag leaf area, tillers number and spike grains, the weight of 1000, and grain yield. The dosage of 200 mg L-1 produced the highest averages for the plant height traits (87.24 cm), tillers number (811.7 tillers. m-2), and grain yield (5.23 mcg. ha-1). Plant spraying treatment with arginine at a dosage of 100 mg L-1 was superior to the number of grains per spike and achieved an average (of 44.58 grains). Regarding the interactions between the study variables, spray plants of the variety Ebaa 99 with arginine at a dosage of (100 mg. l-1). This led to maximum grain yield during the study season. The results indicated that the APA 99 variety was significantly superior in terms of vegetative growth, yield, and its components. Accordingly, these characteristics together contributed to an increase in the total yield. APA 99 responded significantly to higher concentrations of arginine compared to other cultivars.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":" 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831470","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}

The results revealed that the highest infestation was recorded in the control (71.67 %), while the lowest infestation (25.67 %) was observed in the plot treated with B. bassiana (1.5 %). This was followed by Neem kavach-treated plot (4 %) with an infestation rate of 26.67 %, and the clay-treated plot (15 g/L) with an infestation rate of 38.67 %, after the third spray. The impact of these biological agents on cucumber yield was also evaluated. The highest yield, 9.36 kg/plot, was obtained from the B. bassiana-treated plot, followed by Neem kavach-treated plots with yields of 8.94 and 7.28 kg/plot, respectively. The lowest yield of 4.58 kg/plot was recovered in the untreated plots.

These conditions were subjected to 6 different nutrient formulas, including Hoagland solution as control (H), H with 400 ppm potassium (H+K400), H with 300 ppm potassium (H+K300), H with 20 ppm nickel (H+Ni20), H with 10 ppm nickel (H+Ni10), H with 300 ppm potassium and 10 ppm nickel (H+K300+Ni10). The nutrient formulas did not yield significantly different results in terms of per-plant yields for the 2 cultivars. However, the H+K400 treatment showed notably higher lycopene contents, with increases of 1.2-fold for Ranger and 1.24-fold for Sweet Girl cultivars. Additionally, this treatment led to significant enhancements in total soluble solids (TSS) and ?-carotene content in the Sweet Girl cultivar, by 1.09-fold and 1.10-fold compared to the control respectively. Environment E2 provided more favorable conditions for achieving increased antioxidant tomato production, including improvements in fruit color index (red/yellow) by 1.11 to 1.18-fold, fruit firmness by 1.13 to 1.14-fold, TSS by 1.10 to 1.24-fold, lycopene by 1.98 to 2.45-fold and ?-carotene by 3.29 to 5.68-fold.
