Abstract

This experiment was carried out in the field of botanical garden which belongs to Biologi
Department , College of Education (Ibn Al-Haitham), University of Baghdad during the
growing season 2009-2010.The experiment was designed to study the effect 5 concentrations
of Gibberellic acid(GA3)( 25,50,75,100and125mg.L
-1
) and 2 levels of NPK (17:17:17)
fertilizer (200 and 400 Kg.ha
-1
) and their interaction on the rates of absorption and transport
of some macronutrient elements in two varieties of chamomile plant ( Local variety ,
Matricaria chamomilla L. and German variety , Matricaria recutitia L.) . Randomized
Complete Block Design (RCBD) was used with 3 replicates for each treatment .Control plants
were grown in unfertilized soils and not sprayed with gibberellic acid .
Results showed a significant increase in the
absorption and transport rates of N,P,K,Ca and Mg with increased GA3 concentration and
NPK levels in comparision with the control plants The highest rates of absorption and
transport rates were obtained by using GA3 at 75 mg.L
-1
and NPK at 400 Kg.ha
-1
. The local
variety gave highest rates of absorption and transport .This result pointed to the genetic
variations between the two varieties in their response to the studied factores
