Biochar Nanoparticles Reduce Ciprofloxacin Accumulation and Restore Growth and Hormonal Balance in Rice Seedlings

Plants, Journal Year: 2025, Volume and Issue: 14(3), P. 380 - 380

Published: Jan. 26, 2025

Ciprofloxacin (CIP), a widely used fluoroquinolone antibiotic, poses growing environmental concern due to its persistence in agricultural soils and potential adverse effects on crop production. While previous studies have documented CIP’s negative impacts plant growth, effective strategies protect crops from antibiotic stress remain limited. Biochar-based approaches show promise, but their application at the nanoscale for management is largely unexplored. This study demonstrates how biochar nanoparticles (BNPs) effectively mitigate CIP-induced rice seedlings through adsorption mechanisms. Rice were treated with 5 10 mg L−1 CIP, without 0.2 g BNPs. Results showed that CIP significantly disrupted decreasing shoot length by 20.5% root 45.2%, along reduced biomass. Application of BNPs bioavailability over 80%, leading decreased accumulation 49.7% shoots 33.1% roots. The addition mitigated these growth restoring 98.2% control levels improving biomass accumulation. also hormone imbalance, evidenced recovery IAA 8.9%, an increase 6-BA 152.6%, enhancement SA 12.7–13.6%. These findings demonstrate significant reducing systems provide insights into responses under conditions. research offers promising strategy enhancing resilience areas affected pharmaceutical pollutants.

Biomimetic Modification of Waterborne Polymer Coating Using Bio-Wax for Enhancing Controlled Release Performance of Nutrient

Polymers, Journal Year: 2025, Volume and Issue: 17(7), P. 838 - 838

Published: March 21, 2025

Waterborne polymer coated controlled release fertilizers (CRFs) are highly valued for their potential to enhance nitrogen use efficiency (NUE) and reduce fertilization labor costs. However, application in crops with long growth periods, such as rice maize, is limited by inadequate coating strength suboptimal hydrophobicity. Inspired the hydrophobic anti-fouling structure of lotus leaf cuticles, this study biomimetically modified waterborne polyacrylate-coated urea (PACU) using natural bio-wax including bran wax (RBW), candelilla (CAW), bees (BW) carnauba (CW), along paraffin (PW) a control. The modifications significantly extended nutrient duration 22 d compared unmodified PACU, CW providing longest duration, followed CAW, BW, RBW, PW. Additionally, modification exhibited superior hydrophobicity affinity polyacrylate coatings, while inferior hardness toughness PW compromised its performance. Field trials demonstrated that CW-modified CRFs effectively resulting 7.2% increase yield 37.9% maize yield, well an 18.7% improvement NUE conventional fertilizers. These findings offered novel approach thereby enhancing performance applicability long-season crops.

Assessment of the Photosynthetic Response of Potato Plants Inoculated with Rhizoctonia solani and Treated with Flesh-Colored Potato Extracts Nanoencapsulated with Solid Lipid Nanoparticles

Plants, Journal Year: 2025, Volume and Issue: 14(2), P. 156 - 156

Published: Jan. 7, 2025

Potato has great nutritional and economic importance in agriculture. However, Rhizoctonia solani represents a significant risk, reducing the yield quality of potato production. Flesh-colored (FCP) extracts show vitro inhibitory effects against R. solani, although environmental factors may reduce their stability. Solid lipid nanoparticles (SNLs) offer solution by encapsulating these compounds, preventing degradation, improving delivery, positioning solid as promising technology for sustainable extract application. A greenhouse assay at two phenological stages under inoculation was used to evaluate photosynthetic response (photosynthetic parameters pigments) doses nanoencapsulated (SNL + FCP). During commercial fungicide application, stomatal conductance, rate, internal CO2 concentration increased compared with those non-inoculated control (NT), whereas maintained levels similar NT, suggesting possible regulation defense system. In terms pigments, SLN FCP chlorophyll concentrations, unlike inoculated plants, which significantly decreased. Component analysis revealed that lower dose primarily B synthesis, higher control. These findings suggest an improved from fungicides, particularly respect pigments. further research is needed, results indicate potential eco-friendly phytopathogenic fungi
