Efficient Micropropagation of Highly Economic, Medicinal and Ornamental Plant Lallemantia iberica (Bieb.) Fisch and C. A. Mey

Abstract

Lallemantia iberica (Bieb.) Fisch. and C. A. Mey is high valued annual ornamental and medicinal plant from Lamiaceae family that prefers dry sunny hillsides, roadsides, slopes, and fallow fields over an altitude of 500-2150 m. It bears beautiful white flowers and bloom from April to June each year. This study reports L. iberica micropropagation using cotyledon node explants isolated from 15-day-old in vitro regenerated plantlets. The cotyledon node explants were cultured on MS medium containing 0.50, 1.00 plus 2.00 mg/L BAP, 0.00, 0.01, and 0.02 mg/L NAA. Maximum shoot regeneration was noted on MS medium containing 0.50 mg/L BAP. Well-developed micropropagated shoots were rooted on MS medium containing 1.00 mg/L IBA. The rooted plants were easily hardened in the growth chamber and acclimatised in greenhouse.
