Abstract

An experiment was carried out to investigate the effects of different concentrations of GIBBERELLIC ACID (GA3) as foliar application on growth and ESSENTIAL OIL content and yield of LAVENDER based on randomized complete block design with five treatments and four replications. The treatments consisted of different concentrations of GIBBERELLIC ACID (T2=100, T3=200 and T4=300 mg/l), formulated (tablet) GIBBERELLIC ACID (T5) and the control (T1=0). ESSENTIAL OIL of dried shoots and flowering stalks were extracted by hydro-distillation method using Clevenger type apparatus. ESSENTIAL OIL yield was calculated in milliliters per square meter based on the ESSENTIAL OIL content. The results showed that the highest ESSENTIAL OIL content and yield of both shoots and flowers belonged to the 300 mg/l GA3 application. Fresh and dry weight of leaves and stem attained their highest quantities at 300 mg/l GA3 application as well. In contrast, there was significant difference between treatments regarding flowering stalk (inflorescence) fresh and dry weight and the greatest amount for this trait was recorded in the control. GA3 application at 300 mg/l significantly (P<0.05) affected flower bearing plants and the highest number for this trait belonged to the highest level of GA3 i.e.300 mg/l. Like with many of traits, the maximal plant height was also belonged to T4 treatment. Overally, considering the whole results it seems that 300 mg/l GA3 was the most appropriate treatment for foliar spray of LAVENDER plants regarding growth characteristics, ESSENTIAL OIL content and yield.
