In: Journal of Biological Chemistry and Environmental Sciences 2012.v.7(1)Summary: The plantlets of lavender were exposed to seven different dose levels of y-irradiation, 0, 5, 15, 30, 45, 60, and 75 Gy. After that the irradiation plantlets were sectioned to start the multiplication stages, through subculturing every section four weeks intervals for three times. Data revealed that, y-irradiation at low dose levels 5 and 15 Gy, increased all morphological, growth parameters and physiological characteristics of plantlets. The survival percentage of plantlets clearly showed that there were no differences between the dose levels 5 and 15 and the control plantlets, while the dose level more than 15 Gy decreased the survival percentage of plantlets. Dose level of 15 Gy increased significantly the length of plantlets in the three multiplication stages (M1, M2 and M3) and reached 8.00, 9.10 and 10.03 cm, respectively. Key words: Gamma irradiation, chlorophyll, growth parameter, lavandula multifida.
