Effect of Laser Biostimulation on Germination of Sub-Optimally Stored Flaxseeds (Linum usitatissimum)

Sub-optimal storage of grains could deteriorate seed germination and plant viability. Recent research studies have established that laser biostimulation seeds be used as a safe sustainable alternative to chemical treatment for improving crop growth. Herein, the efficacy this novel technique is evaluated see if poor germinability caused by sub-optimal flaxseeds (Linum usitatissimum) reversed using biostimulation. Healthy were first subjected conditions (30 °C ten weeks) degrade their germinability. Two low-cost lasers, including single-wavelength red (659 nm) dual-wavelength green/infrared (531 810 nm (ratio ~10:1)) then on two groups viz. healthy (properly stored) sub-optimally stored (artificially degraded (AD)) irradiated 0 (control), 5, 10, 15 min total power densities 7.8 6.2 mW/cm2, respectively. In case AD seeds, 5-min was found most efficient setting it improved mean percentage, time, speed, rate index, wet weight, dry weight 29.3, 16.8, 24.2, 15.7, 20.6%, respectively, with respect control samples. induce significant enhancement in seeds’ root length, (improved 26, 23, 8%, respectively) under 10 irradiation. On other hand, effect applied not very promising only time 17%). Overall, study demonstrates potential reversing adverse storage. We believe these findings spur development physical tool manipulating
