The Effect of Indole Butyric Acid and the Time of Stem Cutting Preparation on Propagation of Damask Rose Ornamental Shrub
Journal Title: Journal of Ornamental and Horticultural Plants - Year 2014, Vol 4, Issue 4
Abstract
In order to investigate the morphological reactions of cutting of damask rose to IBA (indole butyric acid) in different times, an experiment was done in a factorial experiment based on RCD and three times with three replications and 10 observations per each replication. In this experiment, the simple effects of IBA, time and their interaction effects were measured against morphological properties of damask rose rooting. Important measured factors were the root length, the percentage of rooting, the percentage of callus and the dry root weight. After immersing the cutting in IBA quickly for 5 seconds, the cutting were placed in the medium in a research greenhouse under mist system. According to the findings of the present research, in the simple effect of IBA, their time and interaction, the maximum increase in the average root length was obtained in 4000 mg/L-1 IBA and in cutting taken in winter. Similarly, the maximum rooting percentage was achieved in cutting treated with 2000 and 4000 mg/L IBA in March. The highest root dry weight was gained in March and in a concentration of 4000 mg/L of IBA.
