Abstract
Study was conducted in the city of Mosul during the period 16 October 2006 to 14 June 2007, at a civil nursery in the city of Mosul on the plant of Freesia hybrida L. cv. Prominence Were divided into two groups of Corms soaked in Gibberellic Acid with concentration 300 mg/L before planting for 24 hours and the other group without soaking. The plants Sprayed with micro-elements in 25 mg/L concentration rated one time spraying and two times spraying per month & without the spray as comparison factor until the start of flowering, as well as spraying different concentrations of ascorbic acid is 0 , 50 and 100 mg/L. The results showed that soaking with GA3 has given less number of days until the emergence of agriculture and less number of days for the emergence of the first real leaf and less number of days from agriculture to open the flowers and the highest plant height 52.41 cm and the largest total chlorophyll content 3.44 mg / liter. Spraying rate with micro-elements which contained Fe 3.5% , Cu 0.3 % , B 0.3% , Zn 0.4% , Mn 1.0% , Mg 1.0% once in month has given less number of days for the emergence of the first real leaf, while spraying two times gave the highest content of chlorophyll and less number of days for the emergence of seedling 12.22 and the largest number of leaves before the onset of bud appears 7.78 leave, and longer duration of the flowers on the plant when treated with Gibberellic Acid 12.85 days and the largest number of the Inflorescences on the plant 3.7 Inflore- scences/plant and longer duration of a flower vase 9.62 days.
