| Abstract This experiment was conducted in biology department/college of Education at AL-Qadisyia University to study the effect of different concentration of Gibberellin(50,75,100 mg/L) and Salicylic acid (20,30,40 mg/L) in addition to control and their interaction on vegetative growth, nutrient content , volatile oil as well as active substance(carvon and limonene) of Anethum graveolens L ;Local cultivar. The design of experiment was RCBD in a factorial arrangement in four replication. And the LSD =0.05 was utilized as a method of mean separation whenever treatment effect was evident. Vegetative growth parameters includes: stem diameter, percentage shoot and root weight, tottal chlorophyll and shoot NPK content, percentage of volatile oil in seed and carvon and limonene percentage also determined. Results showed : The use Gibberellin in (100 mg/L) or Salicylic acid (40 mg/L) increased in stem diameter , percentage of dry matter of shoot and root and total chlorophyll content. The highest percentage to nitrogen and phosphorous was at the 100 mg/L Gibberellin , while the concentration of 50 mg/L Gibberellin gave high percentage of phosphorous and the concentration of 40 mg /L Salicylic acid caused high percentage of nitrogen, phosphorous and potassium . The volatile oil and the active substance (carvon and limonene ) were highly increased at the 100 mg/L Giberelline also the 40 mg/L from Salicylic acid increased volatile oil and carvon , Limonene was at highest at the 20 mg/L Salicylic acid .The interaction between Gibberelin and Salicylic acid reveald significant effect on most of vegetative criterion studed on volatile oil content and active substance especially the combination of high concentration from Gibberellin and Salicylic acid . | ||
