Abstract

Carob (Ceratonia siliqua L.) is an important crop in the Mediterranean climate for agriculture and forestry. When the carob orchard is established with seedlings, the juvenile period can be delayed. Additionally, the survival chances of plants are decreased without irrigation. Instead of establishing orchards with seedlings, it is considered that unproductive depressed carob trees in the natural population can be converted into production in a shorter time with reconversion techniques. In this study, it was aimed to convert unproductive young and old trees in a natural forest population into production by using different reconversion techniques. Hard pruning and hard pruning + burning were used as reconversion techniques. After cutting, number of shoots per tree, shoot diameter and shoot length were investigated in young and old trees. In the next phase, the grafting of the shoots for both treatments was done in April and May, 2015. After grafting, survival rate in graft, shoot diameter and shoot length were measured. The results showed that reconversion techniques and tree age significantly affected the number of shoots. The hard pruning reconversion technique yielded the highest number of shoots (114.44) and the largest shoot diameter and length in old trees. Regarding graft survival rate, neither the reconversion technique nor the tree age showed significant effects, while the months of grafting had a significant effect. The maximum graft survival rate was observed in April (100%) while the minimum graft survival rate was 36.11% in May. Based on the findings, both young and old carob trees were deemed suitable for the restructuring plan, with hard pruning being the recommended reconversion technique. Additionally, April was determined as the most suitable time for grafting. In conclusion, reconversion techniques can accelerate the production of carob trees, contributing to sustainable carob cultivation in some areas of Türkiye.
