Micropropagation of Lavandula spp.

Area of Science:

• Plant Biotechnology
• Horticulture
• Plant Physiology

Background:

• Lavender (Lavandula spp.) are economically significant ornamental and medicinal plants.
• Traditional vegetative propagation via stem cuttings is hindered by poor rooting and contamination susceptibility.
• In vitro culture techniques offer a viable alternative to overcome these propagation limitations.

Purpose of the Study:

• To describe effective in vitro propagation protocols for Lavandula viridis and Lavandula vera.
• To highlight methods for improving the propagation efficiency of these valuable plant species.

Main Methods:

• Development of protocols for in vitro culture of Lavandula species.
• Utilizing an 'open culture system' for propagation.
• Focusing on nodal shoot proliferation for L. viridis and leaf-derived callus for L. vera.

Main Results:

• Successful in vitro propagation protocols were established for both Lavandula viridis and Lavandula vera.
• Nodal shoot proliferation was achieved for L. viridis.
• Plant regeneration from leaf-derived callus was demonstrated for L. vera using the open culture system.

Conclusions:

• In vitro culture provides an effective solution for mass propagation of Lavender species.
• The described protocols, including the open culture system, can enhance the efficient propagation of L. viridis and L. vera.
• These methods address limitations of conventional propagation, supporting the cultivation of these important plants.
