Micropropagation of Passiflora species and its hybrids may play an important role in the production of healthy and disease-free plants which can be a source of medicinal herbal products, nutritional fruits and ornamental flowers. The rapid multiplication of elite plants to obtain pharmacognostic material, containing valuable flavonoid C-glycosides, is possible by usingcontrolled in vitro conditions, constituents of the medium and the interactions of plant growth regulators (1-naphtaleneacetic acid, benzyladenine, gibberellin GA3,kinetin, indole-3-acetyl-L-aspartic acid, indole-3-butyric acid, thidiazuron) and influencing various chemical additives (silver nitrate, coconut water, activated charcoal). Investigations of specific requirements during stages of micropropagation, such as the establishment of primary cultures (including type of explants, age of donor plant), shoot multiplication (by direct and indirect organogenesis and embryogenesis), rooting and acclimatization of regenerated plants are summarized in this review. The following species were recently studied for micropropagation: P. alata, P. caerulea, P. cincinnata, P. edulis, P. foetida, P. setacea, P. suberosa. It seems that for awide range of applications of in vitro clones of Passiflora, interdisciplinary studies including genetic and phytochemical aspects are needed.
