Therefore, it is necessary that restoration aims at achieving high genetic diversity of plant populations in addition to the recovery of characteristic species composition and diversity. germplasm is essential for the conservation and utilization of plant genetic resources [13]. (1992) and Hamrick and Godt structure of cytoplasmic genetic diversity in annual or (1996) on a large number of species, indicate that trees short-lived plants are very rare. Also, plant populations that are less genetically diverse may be more susceptible, in some cases, to pathogens or other environmental stresses. Much of the large amount of diversity of a species may be found within individual populations, or partitioned among a number of different populations.
