The Role Of Gibberellic Acid And NPK Fertilizer On Some Growth Characteristics And Active Compound From Two Varieties Of Chamomile

Abstract

An experiment was conducted with the use of two varieties of chamomile plant , Local variety Matricaria chamomilla L. and German variety Matricaria recutitia L. in the field of Biological Department , College of Education (Ibn Al-Haitham) University of Baghdad for growing season of 2009-2010, to study the effect of 6 concentration of Gibberellic acid(GA3)(0 , 25 ,50 , 75 , 100 and 125) ppm and 3 levels of NPK (17:17:17) fertilizer (0 , 50 and 100) Kg / d. and the interaction between them on some growth characteristics and active compounds according to the Randomized Complete Block Design (RCBD) with 3 replicates . Results showed that GA3 concentration and fertilizer level and their interaction had a significant effects on growth characteristics , plant height , number of branches and number of the inflorescence , percentage of oil and concentration of active compounds from the two varieties of chamomile especially at the concentration of 75 ppm from An experiment was conducted with the use of two varieties of chamomile plant , Local variety Matricaria chamomilla L. and German variety Matricaria recutitia L. in the field of Biological Department , College of Education (Ibn Al-Haitham) University of Baghdad for growing season of 2009-2010, to study the effect of 6 concentration of Gibberellic acid(GA3)(0 , 25 ,50 , 75 , 100 and 125) ppm and 3 levels of NPK (17:17:17) fertilizer (0 , 50 and 100) Kg / d. and the interaction between them on some growth characteristics and active compounds according to the Randomized Complete Block Design (RCBD) with 3 replicates . Results showed that GA3 concentration and fertilizer level and their interaction had a significant effects on growth characteristics , plant height , number of branches and number of the inflorescence , percentage of oil and concentration of active compounds from the two varieties of chamomile especially at the concentration of 75 ppm from GA3 and the level of 100 Kg / d. of NPK . Also, results showed , the Local variety surpassed the German variety in the number of branches , number of the inflorescence and percentage of oil, while German variety surpassed the Local variety in the height of plant. GA3 and the level of 100 Kg / d. of NPK . Also, results showed , the Local variety surpassed the German variety in the number of branches , number of the inflorescence and percentage of oil, while German variety surpassed the Local variety in the height of plant.
