Study on the effect of cutting location on shoot and IBA on rooting of ‘Night Jessamine’ (Cestrum nocturnum) stem cuttings

ABSTRACT: In order to evaluate of the cutting location on shoot and Indule butyric acid (IBA) on rooting of ‘Night Jessamine’ (Cestrum nocturnum) stem cuttings, this study was performed as factorial arrangement in randomized complete block design in mist greenhouse with 4 replications and 10 cuttings per replicate. For this purpose was prepared annual shoots of plant as cutting source and was divided from half. Then was prepared 15 cm long cuttings from each part of shoot and was treated by 0 (distilled water), 1000, 1500, 2000 and 4000 mg/L IBA for 5 seconds and was cultured in pots containing sand and peat-moss. After 75 days was recorded rooting percent; grown cutting percent; root number in each cutting; root length; root fresh and dry weight. Based on results, the cuttings of upper part of shoot significantly were better than the cutting of lower part of shoot especially in relation to rooting percent and grown cuttings percent. IBA 2000 and 4000 mg/L significantly were better than other concentrations.
