Demonstrates improved physiological performance in grapevines treated with chitosan-arginine nanoparticles under salinity, suggesting effective stress mitigation strategies.
Key Points
The study aims to evaluate the effectiveness of chitosan-arginine nanoparticles in mitigating salinity stress on grapevines and improving physiological performance.
Evaluated treatments of chitosan, arginine, and their nanoparticle forms under varying salinity levels.
Applied leaf chlorophyll measurements, antioxidant enzyme assays, and geometric morphometric analysis of stomata.
Compared stressed grapevines treated with nanoparticles to untreated controls.
Salinity treatment significantly reduced chlorophyll content and physiological efficiency indicators.
CTS-Arg NPs at 1 mM significantly alleviated damage and improved physiological characteristics compared to untreated plants.
Salinity caused stomatal rounding, while CTS-Arg NP treatment shifted stomata towards an oval shape, indicating better performance.
