In vitro plant regeneration from leaf callus inPiper colubrinum Link

Callus-mediated shoot regeneration from leaf explants ofPhytophthora resistant pepper (Piper colubrinum Link.) is described. The effect of basal media composition and growth regulators onin vitro response of explants was evaluated. Shoot buds were induced and elongated on half-strength MS medium containing 2.0 mg l^–1 BA and 0.5 mg l^–1 NAA , as well as 1.0 mg l^–1 BA and 0.5 mg l^–1 2,4-D. The shoots were rooted in half-strength MS medium with or without IAA or IBA, and then were transferred to soil with 100% survival.
