| Abstract | ||||
| root ability of three fruit species i.e. Kalamata Olive (Olea europaea L.), Betulaefolia Pear (Pyrus betulaefolia L.) and Malus Apple (Malus sylvestris Mill.), under hydroponic units. From private farms, near to El-Sadat city, one year old mature wood cuttings from the three studied fruit species were collected on the end week of January in both seasons. Woods (50-70 cm in length) were prepared and maintained wet in black plastic bags, next day after collection and in the nursery, woods were cut into (12-15 cm) long sections early in the morning. The terminal cuttings were less than 15 cm length and (2-3 mm) in diameter with terminal bud. Where as sub terminal cuttings were (15-18 cm) in length, (3-4 mm) in diameter. The basal cut was made just below anode. Only olive cuttings with 4-5 leaves retained on the upper portion were used. The base of cutting were treated with one of the following Treatments (500 ppm IBA for 5 seconds - Table beet water extract (solution 5 gL-1) for 30 min - 500 ppm IBA for 5 seconds and retreated with table beet water extract for 30 min – Control). The treatments were arranged in a completely randomized design with three replicates for each treatment. Apples cutting treatment recorded the best results compared with olive cuttings in rooting percentage, root number, vegetative growth and leaf nutrients content as well as total carbohydrates and Indole. Terminal cuttings treatment achieved the best results compared with sub-terminal cuttings in rooting percentage, root number, vegetative growth and leaf nutrients content as well as total carbohydrates and indole. The results of the present study clearly demonstrated the effect of a combined treatment of IBA 500 ppm + table beet extract on stimulation of rooting and survival of rooted cuttings compared with a treatment of IBA or table beet alone. This treatment is of particular importance for rooting of difficult root and moderate-rooting cuttings, but is also beneficial for easy to root cuttings, in increasing the survival rate of rooted plants compared with the common treatment of IBA alone. | ||||
