Infrared Laser Processing in Seed Treatment: A Biotechnical Approach

Abstract

This study investigates the impact of infrared laser irradiation on pre-sowing seed treatment across various crop species. Using the Lika-LED device, which allows precise control over irradiation parameters, seeds of wheat, barley, corn, oats, and rice were exposed to infrared light to assess its effects on germination, shoot growth, and overall seed viability. Results revealed that wheat seeds exhibited significant improvements in both germination rates and shoot length, demonstrating the effectiveness of infrared laser treatment in enhancing seed performance. Barley seeds showed increased shoot length after 3 minutes of irradiation, though germination rates remained unchanged. Conversely, corn seeds experienced a reduction in sprout length, while germination rates stayed constant, suggesting a negative impact on growth. Oats and rice seeds did not show statistically significant changes under the tested conditions. The study underscores the potential benefits of infrared laser treatment for certain crops and suggests further research to explore a broader range of irradiation conditions and different seed types. Future investigations will focus on optimizing laser parameters, assessing the effects of laser coherence, and evaluating long-term impacts on crop quality to refine and enhance agricultural practices.
