Abstract

Conocarpus with the scientific name Conocarpus erectus L. is an ornamental shrub that in this study the effect of the treatments: the cuttings type (Hardwood, Semi-hardwood and Herbaceous), cutting time (March 11, April 9) and Naphthalene Acetic Acid (with/without hormone) on survival and growth cuttings of Conocarpus erectus L. were studied. This study by using a factorial design based on completely randomized design with 4 replication and 30 cuttings per treatment in Behbahan municipality’s greenhouse was conducted. The results showed that cuttings planted in April 9 had the highest of vegetative traits such as: shoot wet and dry weight, root length, shoot length and number of leaf but survival percent and root diameter has the highest in cuttings planted in March 11. Hardwood cuttings had the highest number of leaf, shoot length, root length, shoot wet and dry weight. Soft wood cuttings had the highest survival percent and number of roots. Hormone-free cuttings had the highest survival percent, shoot length, shoot dry weight. The best result was observed in softwood cuttings without hormone that planted in March 11.
