Direct regeneration of the medicinal herb Cucumis anguria L from shoot tip explants
A protocol was developed by in vitro regeneration by shoot induction of Cucumis anguria, a plant used as medicine and vegetable belonging to the family Cucurbitaceae. High frequencies of multiple shoot regeneration were achieved from nodal explants on MS fortified with 2 mg/l 6-benzyl amino purine (BAP) and 0.5 mg/l indole acetic acid (IAA). Five to ten shoots per explant were obtained. The elongated...
