In Vitro Propagation of Caper (Capparis spinosa L.): A Review

Caper (Capparis spinosa L.) is a shrubby plant species recalcitrant to vegetative propagation and generally difficult propagate by seeds. This due the difficulties associated with seed germination, root induction from stem cuttings, hardening. Propagation tissue culture would be good alternative promising approach overcome limitations of conventional propagation. Tissue methods can used for clonal caper plants. Indeed, in many species, micropropagation has played decisive role rapid large-scale production uniform genetically stable also genetic improvement conservation programs. In this review, we first provided an overview on its means propagation, then described different micropropagation, i.e., vitro germination seedling development, nodal segmentation elongated shoots (i.e., microcuttings), adventitious organogenesis. These make it possible all obstacles preventing caper. Thus, most updated information progress made field reported future perspectives are outlined.
