Effects of leaf size and IBA on rooting and root quality of Japanese privet, rock cotoneaster and ornamental pomegranate mini-cuttings
This study was conducted to investigate the effects of leaf size (half and full leaf) and indole-3-butryic acid (IBA) (0, 500, 1000 and 2000 ppm) doses on rooting and root quality of privet (Ligusturum japonicum L.), rock cotoneaster (Cotoneaster horizontalis var. perpusillus C.K. Schneider) and ornamental pomegranate (Punica granatum L. 'Nana') leafy mini-cuttings taken from the first half of July. Experiments were designed in randomized block design with 3 replicates for species. Each replicate included 30 mini-cuttings. The mini-cuttings were planted in foamy cell trays (3×3×5 cm) filled with sterile peat moss and placed on rooting benches with bottom heating (22°C) in a glasshouse with 60% shading and misting. For Japanese privet, full leafy mini-cuttings with 500, 1000 and 2000 ppm IBA gave the highest rooting rate (93.33%) while full leaf and 1000 ppm IBA for ornamental pomegranate (97.78%), control and 2000 ppm IBA for rock cotoneaster (66.67%) had the higher rooting rates. However, the highest rooting degree calculated over 1-9 scale were observed as 3.38, 4.63 and 7.00 from Japanese privet mini-cuttings (full leaf with 2000 ppm IBA), ornamental pomegranate mini cuttings (half leaf with 2000 ppm IBA) and rock cotoneaster mini-cuttings (half leaf with 0 ppm IBA), respectively.
