BIOLOGICAL ACTIVETY OF GA3 AND THE FOENICULUM VULGARE MILL EXTRACT ON VEGETATIVE CHARACTERS OF CHAMOMILE (MATRICARIA CHAMOMILLA L.)

Abstract

A field experiment was carried out during the winter season 2010-2011 at the Experimental fields of the Dept. of Field Crops, Coll. of Agric., Univ. of Baghdad. That was to study the spraying effects of foliar application of three levels of Gebberllic acid (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 vegetative growth 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 GA3 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: number of total branches per plant (51.76 branch.plant-1), number of flower branches (42.86 branch.plant-1), number of leaves (142.26 leaf.plant-1), leaf area (55.43 cm.plant-1), chlorophyll content (70.36 mg.gm-1.leaftissue), fresh weight of plant (1477.00 g.plant-1), dry weight of plant (610.33 g.plant-1).
