| Abstract | ||
| A pot experiment was conducted in the screen of the National Research Centre to study the effect of foliar application of kinetin, gibberellic acid and micronutrients on the growth and chemical constituents of Lavandula officinalis L. plant. The obtained results indicated that plant height, number of branches, fresh and dry weights of herb were significantly promoted as a result of foliar application of kinetin, gibberellic acid and microelements or their combinations influenced the vegetative growth of Lavender plants especially when plants sprayed with Ki (40 mg/L) and GAJ (100 mg/L) and with these combinations of microelements (Fe, Mn and Zn) 0.15 %. These effects increased chemical constituents and essential oil yield per plant. The most promising results were obtained from plants treated with kinetin (40 mg/L) combined with microelements and meanwhile, the best oil qualities, i.e., having low content of 1 ,8-cineole and camphor and high content of linalool and linalyl acetate were obtained from the same treatments. | ||
