The study was conducted at the Collage of Agricultural Engineering Sciences,\nUniversity of Sulaimani, Kurdistan Region-Iraq so as to investigate response\nhardwood cuttings of Callistemon viminalis to some plant extracts. The hardwood\ncuttings were taken on 11 March 2021 and soaked separately in 3 and 6 g/L\naqueous extracts of moringa leaf, licorice root, willow shoot, fenugreek seed\nand cinnamon bark for 1 hour. They were compared to the cuttings dipped in 3000\nppm IBA for 10s and control cuttings which were soaked in distilled water for 1\nhour. The experiment laid out in CRD with three replications in a greenhouse,\nand each replication included six cuttings which planted in a mixture of sand\nand rice husk medium. The results showed that the highest (86.66%) rooting was\nachieved in the cuttings treated with 6 g/L licorice extract and they were\nsignificantly different with control cuttings (53.33%), but they were not\nsignificantly different with 3000 ppm IBA (66.66%). Cinnamon 3g/L and fenugreek\n3g/L extracts gave the lowest (6.66% and 33.33%, respectively) rooting and\nother studied parameters. The cuttings dipped in 3000 ppm IBA gave the highest\n(18.91) root number and the highest (66.66%) survival cuttings after\ntransplanting. The longest root (15.54 cm) was found in cuttings were treated\nwith 6 g/L moringa extract. The longest (5.83 cm) shoot was observed in treated\ncuttings with 3 g/L willow extract. The highest chlorophyll a and b (10.08 and\n4.62 mg/L, respectively) were observed in cuttings treated with 6 g/L willow\nextract. Moreover, 3000 ppm IBA gave the highest (20.23%) total carbohydrate\nand (1.77 mg/g) IAA content along with 6 g/L licorice, moringa and fenugreek\nextracts, after 30 days from planting of the cuttings. Licorice root extract at\n6 g/L fairly improved the measurements similar to 3000 ppm IBA throughout the\nstudy.\n
