Summary: This study compared the effects of three zinc species (ZnO NPs, ZnO BPs, and Zn2+) on the seed germination and phytotoxicity of lettuce through hydroponic and pot cultivated experiments. The results showed that all zinc species inhibited the root growth of lettuce and decreased chlorophyll content, CAT, and POD activities. ZnO NPs were observed to penetrate the cells, rupture the plasma membrane, and damage the chloroplast, affecting the growth and development of lettuce plants. Higher concentrations of ZnO NPs and ZnO BPs promoted microbial activity in lettuce roots, as indicated by fluorescence peaks of root exudates.

Summary: The importance of agriculture in human lives and the economy has led to studies focusing on improving crop production. One challenge in improving fertilizer efficacy is reducing leaching losses and increasing nutrient supplies. This study aimed to increase the solubility of zinc oxide (ZnO) by obtaining nanoparticles using different approaches and packaging them in reinforced starch sachets. The results showed that the milled ZnO nanoparticles had better solubility than those synthesized by other methods, reaching a high solubility plateau in 48 hours. The starch sachet system with improved properties from the reinforced insertion of montmorillonite (MMT) showed potential as an alternative source of Zn2+ ions to minimize losses during application.

Summary: This study found that engineered ZnO nanoparticles (NPs) exist in particle and ion states in aqueous solutions, and the phytotoxicity of ionizable metal oxide NP dispersions negatively affects root elongation. Exposure to ZnO NPs leads to accumulation of zinc in roots, inhibition of chlorophyll synthesis, and abnormal cell wall metabolism, which ultimately result in root elongation stagnation and plant death.

Summary: The study found that moderate concentrations of Ag NPs have a stimulatory effect on lettuce plant growth, increasing total phenolic and flavonoid content, and enhancing free radical scavenging activity; however, high concentrations may release silver ions and result in inhibitory effects.

Summary: In this study, innovative slow-release fertilizers were prepared using zinc (Zn) nanoparticles or in bulk, with molasses as an environmentally friendly coating. The results showed that this zinc-coated slow-release urea increased wheat growth and yield, while reducing the release rate of nitrogen and zinc.

Summary: The present study demonstrates a cost-effective and environmentally friendly method for synthesizing Zinc oxide nanoparticles (ZnO NPs) using Cassia renigera leaf extract (CRLE). The synthesized CRLE: ZnO NPs exhibited hexagonal crystallinity and non-uniform grain distribution without agglomeration. They also showed inhibitory effects on the cauliflower pathogen Xanthomonas campestris pv campestris (Xcc) and promoted plant metabolism. The introduction of CRLE: ZnO NPs in cauliflower seeds improved the growth parameters as compared to bare seeds.

Summary: Iron and zinc plant nanonutrients in citrate form were prepared by an eco-friendly solid-state grinding method, resulting in nanosize particles after ball-milling. The nanosized Fe and Zn citrates showed significantly increased plant uptake in soybean crops, attributed to their high mobility as nanocitrates. This suggests that nanocitrates can be an excellent source of plant nutrients in agriculture.

Summary: The study found that Typha angustifolia is able to survive in deeper water than Phragmites australis, possibly because of its greater tolerance to deep water and root aeration. This helps explain the clear zonation of the two species in aquatic habitats.

Summary: The aqueous extracts of Hypochaeris radicata did not affect seed germination, but significantly decreased seedling root elongation, growth, and chlorophyll content in indoor bioassays. However, the effects varied in outdoor experiments on Brassica napus and Erigeron annuus. Further studies are needed to understand the allelopathic effects of H. radicata under dry conditions in mainland Korea as it continues to spread, and to predict its invasion through careful studies and field monitoring in Pacific area countries with changing climates.

Summary: Aquatic plants, such as the water fern Azolla japonica, play a crucial role in freshwater biodiversity but are easily impacted by external factors, leading to endangerment. Research in Korea found populations of A. japonica on Jeju Island, with the most successful growth in distilled water with commercial soil bed treatment. The study also suggests linking endangered species conservation with local agricultural products for habitat restoration, presenting a comprehensive approach for restoring and conserving A. japonica populations.

Summary: This study developed a crop introduction risk assessment system using text mining method to prevent potential side effects of introduced crops. A Preliminary Environmental Impact Assessment Index was designed based on ecological research to evaluate the risks of introduced crops to the natural environment. The study assessed 67 crop species introduced to South Korea and developed protocols and a manual for the preliminary environmental risk assessment of introduced species. The presented crop introduction risk assessment system is effective in identifying potential problem-making crop species.

Summary: Although knowledge about the toxicity of microplastics is still limited, this study investigates the phytotoxicity of 1-μm-sized fluorescent microplastics on free-floating aquatic plants Spirodela polyrhiza and Salvinia natans, as well as emergent aquatic plant Phragmites australis. The study confirms the uptake of microplastics by plants through detection of fluorescence, and demonstrates the phytotoxicity effect on S. polyrhiza and P. australis but not S. natans. This pioneering study provides a baseline for further research on fluorescent microplastic uptake and toxicity in aquatic plants.
