4th Non-Wood Forest Products Symposium, Bursa, Türkiye, 4 - 06 Ekim 2018, ss.7
Autumn olive (Elaeagnus umbellata Thunb.), is a native plant of China, Japan and Korea. The species is a deciduous shrub which can be used for wildlife habitat, and marketed as an ornamental plant. Its edible fruits are exceptionally rich in the antioxidant carotenoid lycopene that has been associated with prevention of certain chronic diseases including prostate cancer. It is important to propagation of this plant because of its fruits which is valuable as a non-wood forest product. In the scope of this study, softwood cuttings taken from autumn olive in July were used. The aim of the study is to determine the effects of different rooting media (perlite and peat) and hormones (IBA 1000 ppm, IBA 5000 ppm, NAA 1000 ppm and NAA 5000 ppm) on rooting of the cuttings. The first root formation date, rooting percentage, root length and the number of roots were determined. The results showed that the highest rooting percentage occurred as 100% in IBA 1000 ppm treatment in perlite rooting media. The highest average values of root length and the number of roots were obtained as 11,69 cm in Control treatment and 7.76 roots in NAA 5000 ppm treatment from cuttings planted in perlite rooting media, respectively. The most suitable propagation conditions for this species, which is important in terms of non-wood forest product, tried to determine. And so, the study will provide a basis for the next propagation researches.
