| Abstract | ||
| The study was conducted in the lethal house of horticultural station unit, Horticulture and landscape Department/Faculty of Agriculture/University of Tikrit to study the effect of the photoperiod (shortening daylight to 9 hours and without shortening daylight), iron foliar every 15 and 30 days in addition to the treatment of non-spray on grafted or non-grafted. The results showed that the treatment of shortening the day caused the earliest in bud burst took place in fall season as recorded 32.96 day, while non-shorting day gave 43.46 day for grafted gardenia. The grafted gardenia response to spray iron and spraying every 30 days gave the highest rate of increasing the plants height to 68.04 cm and the highest rate the flowers number per plant reached 7.30 flowers and fewer buds falling reached 2.13 flower bud. Non-grafted gardenia similar trend response to iron foliar, iron foliar every 30 day treatment gave the highest height of plant 50.50 cm and the highest weight ,diameter and flower age was 3.21g , 3.20 cm and 4.11 day respectively . | ||
