The carob tree cultivation is handicapped by the poor quality of the seedlings leaving the nursery due to the deterioration of the root system, and poor root quality is indeed a factor of failure when placing plants in the field. The objective of this work is to study the effect of root excision to address the problem of the pivotal nature of the root system and mycorrhization to improve the physiological quality of plants at the nursery stage and increase their chance of success in planting.
In addition to their traditional local use in human and animal food, the fruits of the carob tree have a high commercial value in industrial transformation. The demand for fruits and seeds is growing significantly and their commercial value is increasing. It is also an undemanding species, since it is found in various bioclimatic levels (humid, subhumid, semi-arid and arid) and on poor and skeletal soils. The objective of this work is to explore a panel of varieties to be characterized by describing the tree, fruits, and seeds in an illustrated form.
