Laser Irradiation of Vigna Radiata L. (Mung Bean) at Two Wavelengths: Effects on Seedling Development

The use of lasers in agriculture has led to improved growth and development of crops and vegetables, increasing production and ensuring food security. In this study, two laser sources operating at wavelengths of 632.8 nm (He-Ne) and 488 nm (Ar+ ) are used in examining the effects of coherent, low-po...

In this study, two laser sources operating at wavelengths of 632.8 nm (He-Ne) and 488 nm (Ar+ ) are used in examining the effects of coherent, low-power, continuous wave exposure on the development of mung bean (Vigna radiata L.) at an early stage. Pre- sowing laser irradiation of seeds leads to an improvement of mung bean seedling characteristics, with increased values of hypocotyl length (an increase of up to 22.5%), root length (an increase of up to 28.8%), and seedling mass (a maximum increase of 29.2%).
