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 Vigna radiata L. Presowing 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%). Measured parameters between seedlings from laser-irradiated seeds and from control samples are statistically different at a level of significance equal to 0.05. For both laser wavelengths, an optimal exposure time of 2 minutes is determined for enhanced growth of mung bean seedlings.

激光辐射绿豆（Vigna radiata L.）在两个波​​长下增强幼苗发育

在632.8nm（氦-氖）和488纳米（AR波长操作的两个激光源⁺）在检查上的发展相干，低功耗，连续波照射的影响使用绿豆种子L.着陆前的激光照射导致绿豆幼苗特性的改善，下胚轴长度（增加高达22.5％），根部长度（增加高达28.8％）和幼苗质量（最大增加29.2％）的值增加。激光辐照的种子和对照样品的幼苗之间的测量参数在统计学上差异显着，等于0.05。对于两种激光波长，确定2分钟的最佳暴露时间以增强绿豆幼苗的生长。
