Effect of Ultraviolet (uv) Radiation Bonds on Growth and Chlorophyll Content of Dracocephalum Moldavica l.Herb

Abstract: Dracocephalum moldavica L Lamiaceae, is commonly consumed as a food-related product and as a herbal. According new ways in UV effects on live organisms, this research was studied the effect of UV-A and UV-C bands on the herbaceous drug. The plants were grown in a uniform environment in the culture room and exposed to UV rays (20 minutes UV-A daily and UV-C for 10 minutes) after 10 days in six weeks. Indices of fresh and dry weight of aerial and root organs, leaf area, chlorophyll a, b and total chlorophyll con… Show more

“…Examining influence of soil depth on content of heavy metals it is evident that content of all investigated heavy metals slightly decreases with increasing depth, which is to be expected. Contents of Pb, Ni, Cr and Cu in almost all tested samples of soil at the region of Roodsar was significantly higher than limit value [23][24][25][26][27].…”

Other factors that affect the properties of the plant, such as the type of environment in which the plant grows, how it is harvested and how it is processed in order to obtain the extract, by soaking in water, alcohol or other solvents to extract some chemicals [12][13][14]. Manufactured products include dozens of chemicals, including fatty acids, steroids, alkaloids, flavonoids, glycosides, saponins, etc.…”
