Abstract
A field experiment was carried out during the winter season 2010-2011 at the Experimental fields of the Field Crops Dept., College of Agriculture,University of Baghdad. to study the spraying effects of foliar application of three levels of GA3 at 0,100 and 200 mg GA3.L-1 with three levels of Foeniculum vulgare Mill Extract 0,5% and 10%,in a randomized complete block design with three replications.In order to response detect the inflorescence characters on chamomile plant (Matricaria chamomilla L.) common cultivar, in order to determine the best level of growth regulaters which increase efficiency ability of plant production, and study plant morphological changes which result from physiological process,spraying accompanying, more over atrial to access to plant extract which give the same needed effects which hormone Gibberellin marked caused in plant from using some active compounds found in some medical plants which act as growth encouraging factors or growth inhibition factors. Results indicated that treat with GA3 and Foeniculum vulgare Mill extract was significantly increase values of all parameters measure.However, levels of 100 mg GA3.L-1 and the water spraying showed highest values of : the inflorescence stalk length 78.06 cm-1, the time to the appearance of flower buds 125.33 day, the time to the appearance of flowering 142.00 day, number of inflorescence 128.40 flower. plant-1, percentage of fruit─set 83.40%, inflorescence diameter 4.73 cm-1, yield of oil 21.46 L.ha-1.
