The effect of wounding, concentrations of indol butyric acid (IBA) and date taking the cuttings on the rooting of Ficus nitida L.

Abstract

This study was conducted in the greenhouse of Horticulture department in College Agriculture, Al-Anbar University from 1/3/ 2010 to 1/1/2011 using the Terminnl cutting of ficus nitida.L . The stady conducted wounding &diswounding, treating with IBA consintrations (0,3000,5000 or 8000 ) mgL and the dates of taking the cutting (March , April ,May or November) on rooting ability of Terminal cuttings to get good plants were studied in the experiment . the experiment condectedin complete Randomized Design (CRD) were used. Treatment means were Compared in Revised Least Significant Design test ( R.L.S.D ) at 0.05 level of probability. The results could summarized as follows All wounded treatment coaned raising in rooting persent to 51.43 % early in rooting of catting to 32.5 day , dry weiyht of cutting to 0.05 gr , number of Leaves to 35.34 Leve / plant , plant high to 13.19 cm in 6 mounths age .3000 mg /L of ABA treatment want superior than other Treatments in thoae charactrstics to 52.76 % , 30 days, 0.06gr ,38.47 Leaves and 15.54 cm respectivlly . Best rooting and vegetative characterstic of new plants couldbe obtained in march and April date of cutting especially for rooting percentage .mean fresh and dry weigt of which were (59.43 , 78.85) % , (0.08 , 0.05) gr. Respectivlly , were as vegetative characterstics (94.44 , 20.33) leaves / plant and (7.91, 3.61)branch/plant and hight (11.66 , 14.5) cm plant after gmanthe from plating
