| Abstract | ||
| Lavender ( Lavandula angustifolia L) is an important medicinal and ornamental flower plant. This study aimed to evaluate the effectiveness of GA3 and β-CD on lavender growth and oil content under our regional conditions. Field experiment was conducted through 12/3 to 27/12/2024 at the Grdarasha research center field, Ministry of Agriculture and water resources, Kurdistan region-Iraq. The experiment was laid out in Randomize Completely Block Design replicated three, included effect of GA3 ( 0 , 150 ,300. 450 mg.l-1) and β-CD (0 , 1.5 , 3.0 , 4.5 mg.l-1 ) on growth , flowers oil content of (Lavandula angustifolia L. cv. Hemus) .Regarding GA3 treatment, the results showed that the highest number of branches.plant-1(43.25%) was observed from 300mg.l-1, number of flower.plant-1 (513.11) measured 450mg.l-1 and highest oil content per 50g dry weight of flowers (0.51ml) measured from 450 mg.l-1. However, β-CD caused highest plant height and number of branches.plant-1 (45.96 and 45.43 % respectively) in 4.5mg.l-1. Best result of oil content (0.55ml) was obtained from 450mg.l-1 GA3 and 4.5mg.l-1 β-CD combination treatment. | ||
