This study was conducted to monitor the effectiveness of seed priming with cold plasma and supplementation of rooting medium with SiO₂ nanoparticle (nSi) on growth, physiology, and anatomy of Astragalus fridae. The plasma-primed seeds (surface power densities of 0.84 W cm⁻²; 0, 30, 60, and 90 s) were cultured in medium containing nSi (0, 5, 40, and 80 mg l⁻¹). Ultra-structural analysis manifested...
The current research was carried out to reveal the possible impacts of cold plasma on growth and physiology of wheat, as a new approach in plant science. Short and long-term impacts of different types of plasma (nitrogen and helium) with surface power density of 0.4 W cm-2, exposure times (15, 30, 60, and 120 s), and repetitions (1, 2, and 4 times with 24 h intervals) were evaluated. Single-time applied...
Antimicrobial activities of the methanolic extracts from the leaves and flowers of Lippia nodiflora L. (Verbenaceae), were studied by the disk diffusion method. The extracts showed antimicrobial impact on bacteria such as Bacillus subtilis, B. cereus, Micrococcus luteus, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumonia, K. oxytoca and Esherichia coli as well as fungi such Aspergillus...
This paper reports a study of the alkaloid content of different parts of Datura stramonium L. (Solanaceae) in various stages of its growth and development, and the location, structure and ultrastructure of alkaloid-biosynthesizing cells (idioblasts) in different parts of naturally grown and cultured plant material. TLC, HPLC, and GC/MS methods were used for alkaloid assays. The results showed that...
