Laser Irradiation Effects at Different Wavelengths on Phenology and Yield Components of Pretreated Maize Seed

Key Findings

• Blue laser light at an 85-second exposure time achieved the highest seed yield of 7003.4 kg/ha.
• Blue and green lasers increased the number of rows per ear to 39.1 and 45 respectively, compared to a control of 36.
• Plant height was comparatively higher in blue laser light treatments reaching 211 cm.

This study compared the biostimulating effects of red, green, and blue laser wavelengths on pre-treated maize seeds. By exposing seeds to monochromatic laser light for durations of 45 to 105 seconds, the researchers significantly improved the phenology and yield components of the crop. The blue laser wavelength proved most effective for maximizing grain yield and increasing the number of kernel rows on each ear.
