Effect of spraying with glutamic acid and nano zinc oxide on the active substance and some anatomical characteristics of Lavendula Angustifolia

The study was conducted in the wooden canopy of Department Horticulture and Landscape Engineering / College Agriculture Tikrit University during growing season 2021-2022, to effect spraying with glutamic acid nano-zinc oxide on some vegetative growth characteristics, mineral content, active substance anatomical characteristics Lavendula Angustifolia Mill. A factorial trial carried out two factors, first factor at three levels (0, 100, 200) mg. L-1 second are zinc nanoparticles four 0.50, 1, 1.50) g. According RCDB (Randomized Complete Block Design) replications, most important results summarized as follows:Estimation compounds volatile oil lavender leaves: interaction treatment G2Z3 (spraying a concentration 200 + nano 1.50 L-1) characterized by giving highest phenolic leaves (Linalyl acetate, Linalool, Lavandulyl). acetate) which reached (33.32 - 20.69 120.4) respectively, compared lowest concentrations comparison treatment.
