Carob Tree: A Suitable Species for Future

Global warming and environmental stresses and other limitations impose the man to pay more attention to minor (or underutilized or neglected) crops. One of these valuable multifunctional neglected crops is carob tree. There are several trees of this genus in different parts of south of Iran, especially in Kazeroon (Shapoor cave, ancient area). Therefore, this species is potentially suitable for arid and semi-arid climates of Iran. Carob is an evergreen and dioecious tree in Fabaceae family. Species of carob show great tolerance to abiotic stresses such as drought, salinity, high pH (calcareous soil), high summer temperatures (up to 50 oC), air pollution and low soil fertility. Sugary pulp of pod is used as animal and human food. A useful gum is extracted from carob seeds. Also carob tree is useful as ornamental plant for landscaping, windbreak and forestation. This review will discuss carob potentials and how its cultivation can be expanded in proper areas of Iran.
