Germination of lavender (Lavandula angustifolia) plant seeds and production of its seedlings callus cultures

Year: 2024

Type: article

Abstract: Aims: This study aims to find an efficient technique for germinating the dormant (Lavandula angustifolia) seeds. Methodology and results:The seeds were treated by freezing, scratching and immersion in different concentrations (1, 0.5, 0.25, 0.1 g L -1 ) of the gibberellic acid solution for 24 h.The results appeared when seeds immersed in 0.5 g L -1 gibberellic acid stimulated the high germination percent and the rate reached 75% after 6 days and was superior to the other treatments.The results referred to the callus initiated from hypocotyl stems and leaves of lavender seedlings on solid MS medium containing 3.0 mg L -1 naphthalene acetic acid (NAA) and 10 mg L -1 benzyl adenine (BA) after 20 days.It is distinguished by its green color and its semi-cohesive texture.In addition, it is developed from stems, while yellowish-green color and friable when initiated from the leaves; subculture the two types of callus after 15 days produced good cultures.Conclusion, significance and impact of study: Several methods can be used successfully to break the dormancy of lavender seeds.The technique of immersion in GA3 solution by 0.5 g L -1 for 24 h improved over the rest of the techniques in its ability to germinate seeds for 6 days.
