Effect of low power laser irradiation on bio-physical properties of wheat seeds

Abstract

The production of quality food is indispensable and essential to overcome its global shortage. In order to exercise the facile route to acquire massive production, a laser irradiation treatment method was established. We have investigated the effects of diode laser irradiation on wheat seeds germination, its early growth and biochemical parameters. The variation in germination parameters, caused by laser treatment were monitored carefully. A comparison study was accomplished to examine the laser irradiation effects on treated and control seeds. The red laser indicated an enhancement of 25% in germination percentage, 4.68 cm in shoot length, and 0.64 cm in root length while green laser showed 6.25% less germination percentage than the untreated seeds. Further green laser showed 9.67 cm increase in shoot length, 5.39 cm in root length as compared to untreated seeds. It was found that the seeds which were irradiated with green laser showed an amount of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD), of 11.9, 10, and 1.53 per mg of protein, respectively as compared to control seeds. Thus, these investigations are promising and suitable for upcoming research on a large scale.
