  • Seeds treated with chitosan nanoparticles showed higher levels of alkaloids and antioxidant activity, enhancing their medicinal properties
  • The study suggests that chitosan nanoparticles can help plants manage oxidative stress better, improving overall plant health and resilience
Nanotechnology has become increasingly significant in various aspects of daily life, including agriculture. Researchers from Alexandria University conducted a study to evaluate the potential of chitosan nanoparticles in enhancing seed growth and yield by inducing secondary metabolism in Pancratium maritimum L., a valuable medicinal plant[1]. In this study, seeds of Pancratium maritimum L. were soaked in chitosan nanoparticle solutions at concentrations of 0.1, 0.5, and 1 mg/ml for different durations (4, 8, and 12 hours). The researchers measured various germination parameters such as germination percentage, velocity, speed, energy, index, mean germination time, seedling shoot and root length, shoot-root ratio, seedling vigor index, plant biomass, and water content. Additionally, they recorded the levels of alkaloids and antioxidant activity in the plants. The use of chitosan (CHT) in agriculture is not new. It has been proven to stimulate plant growth, protect edible products, and induce stress tolerance in various horticultural commodities[2]. Chitosan's ability to interact with chromatin and directly affect gene expression makes it a valuable tool for enhancing crop productivity. Recent innovations have seen the synthesis of chitosan nanoparticles as a delivery system for fertilizers, herbicides, pesticides, and micronutrients, promoting balanced and sustained nutrition[2]. The study by Alexandria University builds on this foundation by exploring the specific effects of chitosan nanoparticles on Pancratium maritimum L. The results showed that seeds treated with chitosan nanoparticles exhibited improved germination parameters compared to untreated seeds. This suggests that chitosan nanoparticles can enhance seed vigor and overall plant health. Moreover, the study found that the treated seeds had higher levels of alkaloids and antioxidant activity. Alkaloids are important secondary metabolites in plants with various medicinal properties. The increase in antioxidant activity indicates that chitosan nanoparticles may help plants better manage oxidative stress, which is crucial for maintaining cellular health and improving resilience against environmental stresses. Previous studies have shown that nano-anatase, a form of titanium dioxide, can promote antioxidant stress in plants under UV-B radiation by decreasing the accumulation of harmful reactive oxygen species and increasing the activities of antioxidant enzymes[3]. Similarly, chitosan nanoparticles may enhance the plant's antioxidant defense mechanisms, contributing to better growth and stress tolerance. Another study demonstrated that nanosized titanium dioxide could improve seed germination and seedling growth in wheat, with optimal concentrations promoting better outcomes than bulk titanium dioxide[4]. This aligns with the findings of the current study, where chitosan nanoparticles at specific concentrations significantly improved germination parameters and seedling vigor in Pancratium maritimum L. In conclusion, the study conducted by Alexandria University highlights the potential of chitosan nanoparticles in enhancing the growth and yield of Pancratium maritimum L. by improving germination parameters, increasing alkaloid content, and boosting antioxidant activity. These findings contribute to the growing body of evidence supporting the use of nanotechnology in agriculture to promote sustainable crop productivity.
