Abstract: | The effect of low-intensity laser radiation on the accumulation of secondary products of lipid peroxidation was studied in wheat (Triticum aestivum L.) tissue culture. A five-min-long callus irradiation by the helium-neon laser light with the wavelength = 632.8 nm and the intensity of 10 mW resulted in an increase in the accumulation of the products of reaction with thiobarbituric acid (TBA-reactive products). The effect was less pronounced within two days after laser treatment, but even in this case the content of TBA-reactive products was greater than in the control. The data obtained confirm that the low-intensity laser radiation can induce lipid peroxidation processes in plant tissues. |
