Abstract

The results of the effect of laser radiation on germination and yield of wheat under NaCl concentrations (i.e., 0, 100, 200 and 300 mM NaCl) are reported in irrigated water Final Germination Percentage, Mean Time for Germination, Mean Daily Germination, Daily Germination Speed and Yield were determined for Two diode\lasers, emitting 660nm semi-coherent red beam and 980nm infrared beam, and one second harmonics of Neodymium-Yttrium-Aluminum Garnet (Nd:YAG) laser emitting 532nm were chosen as illumination sources. The seeds of wheat were irradiated for 12 minutes. The standard germination test and yield improved significantly by increasing the intensity dose of laser irradiation. All different types of evaluated laser radiation (Red, Infra-Red and Nd:YAG lasers) improved standard germination test and yield considerably compared to control samples. Results showed that the best efficiency was related to Nd:YAG laser with two times illumination. Consequently, application of semi-coherent laser radiation, as a pretreatment, can significantly enhance the resistance of wheat to salinity stress comparing to the controlled samples.
