| Abstract | ||
| The study was carried out at Al-Zawraa park Mayoralty of Baghdad on Fall season 2014/2015,to envistage investigate the Influence of soaking Freesia Corms Golden Melody cv. in Epibrassinolide(Ep(at 0,0.05and 0.1mg l-1 and foliar application of N-(2-chloro-4-pyridyl)- N-phenylurea) (CPPU) at 0,10 and 20 mg l-1 on flowering and corm production .The results could be summarized as follow: soaking corms at 0.1mg l-1 of Ep(Ep0.1)was significantly increased the flowering characters: number of inflorescences plant-1(3.97), number of florets inflorescence-1 (10.81), length of peduncle (14.28 cm), diameter of peduncle (3.39 mm), diameter of basal floret (5.28 cm), plants bloomed earlier(97.08 days,while 0.05 mg l-1 of Ep was more effective on flowering period (15.92 days),and vase life (10.13 days). Soaking corms improved corm characters as well,the level of EP at 0.1mg l-1 was more effective on increasing number of corms plant-1 (2.47), corm diameter(26.28 mm), dry matter of corme (29.08 %), number of cormels corm-1 (4.92), diameter of cormel (11.37 mm), and dry matter of cormel (19.57%) . Foliar application of Freesia plants with CPPU at 20 mg l-1 increased flowering parameters: number of inflorescences plant-1 (4.07), number of florets inflorescence-1 (11.40), length of peduncle (13.69 cm), diameter of peduncle(3.48 mm),diameter of basal floret(5.25cm),flowering period(17.90 days),vase life(11.93days),in addition , plants bloomed earlier (97.07 days). Spraing plants by CPPU at 20 mg l-1 significantly increased: number of corms plant-1 (2.54), corm diameter(26.08 mm), dry matter of corme (29.21%), number of cormels corm-1 (5.14), cormel diameter(11.34 mm) and dry matter of cormel (19.71 %) . The interactions between Ep0.1 and CP20 was superior on improving all characters tasted eccept of flowering period and vase life which the treatment EP0.05 * CP20 was the most effective . | ||
