Interpretive Summary: Many fruit species are propagated by vegetative methods such as budding, grafting, cutting, suckering, layering etc. to avoid heterozygosity. Carob trees (Ceratonia siliqua L.) are of highly economical value and it is among the most difficult-to-propagate. In this study, air-layering propagation method was used to compare wild and cultivated (called as Sisam) carob types. One year old carob limbs were air-layered with coco peat medium by wrapping with aluminum foil and polyethylene film. Initial roots were observed after three months of treatment and the well rooted limbs were cut-off after six months of treatment. Root length, diameter, and the number of roots were recorded on treated shoots and the rooted shoots were transferred into soil. This study demonstrated that genetically important carob types may be propagated rapidly by air-layering method.

Technical Abstract: Many fruit species are propagated by vegetative methods such as budding, grafting, cutting, suckering, layering etc. to avoid heterozygosity. Carob trees (Ceratonia siliqua L.) are of highly economical value and it is among the most difficult-to-propagate fruit species. In this study, air-layering propagation method was investigated for the first time to compare wild and cultivated (Sisam) carob types. In the experiment, one year old carob limbs were air-layered on coco peat medium by wrapping with aluminum foil and polyethylene film. Root initiation was observed after three months of treatment and the well rooted limbs were cut-off after six months of treatment. Root length, diameter, and the number of roots were recorded on treated shoots and the rooted shoots were transferred into potted soil. As a result, we found that in particular genetically important carob types may be propagated rapidly by air-layering method.
