“…As for [ 11 ] , they reported that choosing the appropriate catalyst increases the effectiveness of the accumulation of synthesized compounds, although the mechanism of action of the catalyst to increase the production of secondary metabolism is not clear until now. Ultra-violet (UV) rays are non-ionizing rays whose photons have a high enough energy to cause the transfer of electrons between the orbits of the atoms of the molecules that make up the material that has been exposed to radiation, and thus these atoms move from the original state to the excited state [ 12 ] . The effect of UV rays when wanting to increase the plant tissue productivity of a compound or group of compounds depends on several factors, including the type of plant and the type of tissue exposed to rays, on the compound or group of compounds to be increased, on the intensity of the rays and the duration of exposure Its plant tissue as well as other physiological factors such as the moisture content of plant tissue [ 13 ] .…”

This study was carried out in the plant tissue culture laboratory of the College of Agriculture - University of Karbala for the period from 2021 to 2022. The study included the use of plant tissue culture technique to obtain vegetative branches of rosemary using physical and chemical stimuli as well as plant growth regulators, the experiment was done by cultivating sterile branches tips With a length of 2 cm on MS medium prepared with different concentrations (0, 10, 20, 30) mg.L-1 SA, Then the cultivated plants were exposed to ultraviolet rays at different intervals (10, 20) minutes for each concentration of SA. The results of the study showed that the concentration of 10 mg.L-1SA achieved the highest rate in the number and length of branches that reached (7.45 branches.Plant-1, 3.63 cm) respectively, while the concentration of 20 mg.L-1 achieved the highest average for the number of leaves and the fresh and dry weight of the shoot, and the average concentration of chlorophyll and carbohydrates in the shoot reached (16.86 leaves.plant-1, 3424 mg.gm-1, 2373 mg.gm-1, 3.57 and 4.28 mg.gm-1) respectively, and the effect of UV rays at 20 minute exceeded in achieving the highest average of the measured traits, which included the number and length of branches, number of leaves, fresh and dry weight of the shoot, as well as the average concentration of chlorophyll and carbohydrates in the shoot (7.24 branches.plant-1, 4.04 cm, 16.89 leaves.plant-1, 3374 mg.gm-1, 2141 mg.gm-1, 3.67 and 4.32 mg.gm-1) respectively, while the comparison treatment achieved the lowest rate It reached (3.59 branches.plant-1, 2.39 cm, 14.21 leaves.plant-1, 2810 mg, 1366 mg, 2.56 mg.gm-1, 3.38 mg.gm-1) respectively.
