A protocol for in vitro multiplication of caper (Capparis spinosa L. subsp. rupestris) from nodal segments collected from mature plants was developed. For shoot multiplication, one auxin (indol-3-butyric acid, IBA) and cytokinins of two different classes were used: the N6-substituted adenine derivatives 6-benzylamino purine (BAP), and the two synthetic phenylurea derivatives Nphenyl-N0-benzothiazol-6-ylurea (PBU) and N-phenyl-N0-(1,2,3-thidiazol-5-yl) urea (thidiazuron, TDZ). Maximum shoot production was achieved from explants cultured with the adeninic cytokinin BAP (4 lM) and the auxin IBA (0.5 lM). New shoots longer than 1 cm were used for rooting. To induce root formation, three auxins [indole-3-butyric acid (IBA), 1-naphthaleneacetic acid (NAA) and 3-Indoleacetic acid (IAA)] and two synthetic phenylurea derivatives [N,N-bis-(2,3-methylenedioxyphenyl)urea (2,3-MDPU) and N,N-bis-(3,4-methylenedioxyphenyl)urea(3,4-MDPU)] were used. All rooting compounds tested stimulated the formation of roots. However, the best result in terms of a high percentage of rooted shoots having awell-developed root system with many lateral roots was achieved with the synthetic phenylurea 2,3-MDPU (1 lM) with 93.7% of well rooted plantlets. About 80% of rootedplantlets were successfully acclimatized and transferred to the greenhouse.
