Direct plant regeneration of curry leaf tree (<Emphasis Type="Italic">Murraya koenigii</Emphasis> koenig.), an aromatic plant

Summary An efficient protocol for plant regeneration from stem segments of Murraya koenigii was developed by culturing on Murashige and Skoog (MS) medium supplemented with 2.5 mg l⁻¹ benzyladenine (BA), 25 mgl⁻¹ adenine sulfate, 0.25 mgl⁻¹ indole-3-acetic acid (IAA), and 3% sucrose. The frequency of shoot bud regeneration was higher on similar medium in subsequent subcultures. The regenerated shoots were rooted on half-strength basal MS medium supplemented with 0.25–0.5 mgl⁻¹ IAA or 1-naphthaleneacetic acid (NAA) within 8–12 d of culture. The maximum percentage of rooting was obtained on MS medium supplemented with IAA and NAA, each at 0.25 mgl⁻¹. During acclimatization, 95% of rooted plantlets survived were grown normally under greenhouse conditions.
