Chitosan Nanoparticles: An Alternative for In Vitro Multiplication of Sugarcane (Saccharum spp.) in Semi-Automated Bioreactors

Plants, Год журнала: 2025, Номер 14(11), С. 1697 - 1697

Chitosan nanoparticles (CsNPs) are biocompatible, biodegradable, and non-toxic natural polymers at low concentrations with diverse applications in vitro plant tissue culture. This study aims to evaluate the effect of CsNPs during multiplication sugarcane (Saccharum spp.) using temporary immersion bioreactors. were evaluated 0, 25, 50, 100, 200 mg L−1 Murashige Skoog liquid culture medium. After four weeks culture, response percentage, number shoots per explant, shoot length, leaves dry matter, chlorophyll content, β-carotene lipid peroxidation, phenolic hydrogen peroxide antioxidant capacity evaluated. The results showed that highest percentages obtained treatments 50 CsNPs, whereas lowest 100 CsNPs. Concentrations 25 promoted cell growth differentiation, inhibited it. Chlorophyll content increased by Lipid peroxidation increasing CsNP concentrations. decreased In conclusion, an alternative for stimulating differentiation sugarcane.

Effects of Aqueous Extracts of Lantana camara L. on Germination of Setaria viridis (L.) P.Beauv. Seeds with Different Degrees of Dormancy

Setaria viridis (green foxtail) is an invasive weed species in various agricultural systems, prompting the search for effective compounds to control its germination. The has primary and secondary dormancy depending on time elapsed since post-harvesting, making management strategies more difficult. Several plants, such as Lantana camara L., can be a source of allelochemicals with herbicidal effects, being potential candidate S. viridis. We investigated effects L. extracts germination initial growth seeds different degrees revealed dose-dependent bioherbicide effect. Aqueous were analyzed by HPLC-DAD applied (0.1 5.0 mg/mL) 12- 110-day post-harvest seeds. Seeds evaluated daily percentage (GP), speed index (SGI), radicle length (RL) calculated. Phenolic acids flavonoids major components extract. Lower concentrations 0.5 stimulated accelerated viridis, breaking dormancy. Both 1.0 mg/mL hindered germination, especially 12 dph concentration resulted longer roots, whereas inhibited root development. potentially stimulate at low while inhibiting these parameters higher doses. These results may open new possibilities using weed-control strategies.
