Wheat seeds (Triticumaestivum L.) were exposed to two different types of lasers, a He-Ne laser (633 nm) and an argon laser (514.5 nm), to study their effects on growth, germination, and physiological and biochemical characteristics such as the amounts of chlorophyll a, chlorophyll b, and carotenoids. A significant increase in the growth characteristics was monitored and studied keeping in view the length as well as fresh and dry weight of shoots and roots. Similarly, plant pigment contents such as chlorophyll a, chlorophyll b, and carotenoids were significantly changed. These significant alterations led to an increase in growth and germination compared with unexposed (control) wheat seeds. The experimental results of this in vitro study clearly demonstrate that different lasers like He-Ne laser and argon laser at low power significantly enhance the growth and germination of wheat seeds (Triticumaestivum L.) by positively influencing its physiological and biochemical characteristics.

“…The laser is an abbreviation of "light amplification by stimulation of radiation." 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.…”

Background: Moringa oleifera L. (moringa) is a promising plant for nutritionally and medicinally uses. The influence of laser radiation on moringa seeds (dry and wetted) was investigated, using helium-neon (He-Ne) laser source at ʎ = 632.8 nm wavelength and 5 cm beam diameter for 25, 45, and 90 min. Agro-morphological criteria, SDS-PAGE protein banding patterns, and ISSR markers were investigated to elucidate the influence of He-Ne laser on moringa.Results: Most agro-morphological criteria increased especially with wetted seed group pre-laser treatments (25 min). SDS-PAGE and ISSR profiles showed changes which include the absence of some bands and the appearance of few novel bands. ISSR markers showed a change in band number in all investigated samples with a total number of 172 bands. The polymorphic bands were 91 bands with 19 unique bands. The average mean percentage of polymorphism was recorded 52.91% at samples treated with a laser at different times. Wetted seed treatment for 25 min recorded 40 bands as new bands. Genetic template stability (GTS) values were recorded in all treatments. The lowest GTS % was recorded 76.74 at 25 min (wetted seeds) while highest GTS % was recorded 83.72 at 25 min (dry seeds). According to the data of GTS, produced by laser treatment for 25 and 45 min for wetted and dry seeds, respectively, it is more effective on genome stability than other treatments. Conclusion: He-Ne laser treatments of wetted seeds achieve biostimulation in many aspects of agromorphological criteria. ISSR analysis is a highly sensitive method for the detection of DNA alteration induced by laser treatments. The exposure of dry and wetted seeds to He-Ne laser at different times affected the genomic template stability percentage (GTS %). Also, the laser treatments have a great effect on gene expression by switching on or off some genes that may lead to the presence or absence of certain proteins, respectively.

“…Some researchers argue that exposing seeds to light stimulation could improve the quality of yields, including the chemical composition of plants, e.g. by increasing the sugar content in sugar beet roots (Sacała et al 2012), increase the content of minerals and specific protein in alfalfa (Ćwintal et al 2010), or increase the content of chlorogenic acid responsible for aubergine fruit's antioxidative qualities (Swathy et al 2016).…”

The leaves of scorzonera are vulnerable to mechanical damage due to heavy rainfall or wind. The aim of the study was to determine the impact of pre-sowing exposure of scorzonera seeds to laser light on the mechanical strength of the leaves and the content of photosynthetic pigments. The research material consisted of scorzonera leaves obtained from seeds treated with He-Ne laser light at the wavelength of 632.8 nm, surface power density of 5 mW cm-2 , and exposure time of 1, 5, 10, and 30 minutes. Young's modulus measurements showed that the leaves of the plants grown from seeds subjected to laser light stimulation were characterized by better mechanical strength compared to the leaves of the control. The highest values of the Young's modulus were recorded for scorzonera plants grown from seeds subjected to laser light exposure for 10 minutes. Exposure to light for a period of 1, 5 and 30 minutes significantly affected the content of chlorophylls and carotenoids in the leaves relative to the control. The largest increase in the content of photosynthetic pigments was recorded for 1 minute. The improvement in the mechanical strength of scorzonera leaves may reduce their vulnerability to mechanical damage during vegetation.
