Comparison of HeNe laser and sinusoidal non-uniform magnetic field seed pre-sowing treatment effect on Glycine max (Var 90-I) germination, growth and yield

Laser Irradiation Induces DNA Polymorphism and Alters Phytochemicals Compositions as well as Growth and Yield of <i>Curcuma longa</i>

“…Laser bio-stimulation effects on plant growth was first reported in 1970 [6] and subsequently supported by many studies in various plant species ranging from crops to vegetables and herbs [7,9,[11][12][13][14][15][16]32].…”

“…Shiga, Shoji [38] have reported that red light illumination enhanced Rosmarinic acid content and antioxidant activities in Ocimum basilicum L plants as compared to blue light illumination. Studies from soy beans [9], sweet basil [16], fennel and coriander [17], anise and cumin [18] also indicated that seeds produced from plants grown from pre-sowing laser irradiated seeds contained higher essential oils contents as compared to that produced from the control plants derived from untreated seeds. The authors have attributed the increase in essential oil contents partly as the result of increased growth and metabolisms.…”

“…An extensive list of different laser devises that have been used as biostimulator devise in plant growth was compiled by Hernandez et al [7]. In addition to this list, recent studies on wheat [8], soy bean [9,10] , sunflower [11] , Celosia argentea [12], or vegetables and herbs such as fennel, coriander, anise, cumin, sweet basil, scorzonera, moringa and sage [13][14][15][16][17][18] have provided numerous evidences on the laser bio-stimulation effects ranging from increase germination rate, to plant growth, as well as enhancement and increase in secondary metabolites compounds.…”

The influence of He-Ne laser on agro-morphological criteria, ISSR marker and SDS-PAGE of Moringa oleifera

“…Recently, it was observed that the physical methods had a biostimulatory role in a majority of agricultural crop plants. He-Ne laser was considered the most significant biophysical methods for enhancing the plant seed germination, different growth parameters, and plant development (rendering them safe and friendly to the environment) (Asghar et al 2017). Similar results were investigated by Urva et al (2017), who stated that seedling growth parameters for 10day-old seedlings were enhanced under the effect of 25, 50, and 75 mJ low-power continuous-wave laser light in Moringa oleifera, and optimum laser energy level has more acceleratory effect since at three laser energy levels, the responses were significant.…”

“…Nowadays, the application of laser gained more attention in the field of agriculture (Pandey et al 2015 andSwathy et al 2016). Many studies have been reported the effect of laser on pre-sowing seeds in different crops and vegetables (Thatoi et al 2016, Asghar et al 2016, and Asghar et al 2017. Laser radiation on seeds stimulates a series of positive effects such as enhancement of plant growth, reduction of germination time, increase in the number of flowers per plant, and increase of yield (Niculita et al 2008).…”
