Optimizing germination conditions of Ghaf seed using ZnO nanoparticle priming through Taguchi method analysis

Area of Science:

• Agricultural Science
• Environmental Science
• Materials Science

Background:

• Ghaf trees are vital for arid ecosystems but face germination challenges due to hard seed coats.
• Innovative strategies are needed to improve Ghaf seed germination for ecological restoration and desertification mitigation.

Purpose of the Study:

• To optimize Ghaf seed germination using zinc oxide (ZnO) nanoparticle priming.
• To identify the optimal parameters (duration, concentration, temperature, agitation) for ZnO nanoparticle treatment using the Taguchi method.

Main Methods:

• The Taguchi method was employed for efficient experimental design to optimize ZnO nanoparticle priming parameters.
• Analysis of Variance (ANOVA) and regression analysis were used to assess the significance of variables and interactions.
• Validation tests were conducted using predicted optimal parameters.

Main Results:

• ZnO nanoparticle concentration was identified as the most influential factor for Ghaf seed germination.
• Optimal parameters determined through the Taguchi method resulted in a low error ratio (1-6%).
• Seed priming with ZnO nanoparticles significantly enhanced Ghaf seed germination from 15% to 88%.

Conclusions:

• The Taguchi method effectively optimized ZnO nanoparticle treatment for Ghaf seed germination.
• ZnO nanoparticle priming presents a novel and highly effective approach to improve Ghaf seed viability.
• This method holds significant potential for sustainable agriculture and ecological restoration in arid regions.
