Micropropagation and in vitro culture of Pyrethrum [Chrysanthemum cinerariifolium (Trev.) Vis.]
2014
Pyrethrum (Chrysanthemum cinerariifolium (Trev.) Vis. = Tanacetum cineariaefolium (Trev.) Schultz-Bip.) is a perennial herbaceous plant belonging to the family Asteraceae, native to Albania and the area of former Yugoslavia. It is the only species in the genus Tanacetum having an agronomic importance, although the genus consists of several species producing similar types of bioactive metabolites. The species is grown in order to obtain the insecticidal compounds collectively termed pyrethrins, which are found primarily in the flower heads. In this work we discuss the results found from a worldwide literature review about the micropropagation techniques followed on Pyrethrum, the in vitro cu…
Long-Term Field Evaluation of Conventional vs. Micropropagated Plants of Chrysanthemum cinerariifolium
2022
Pyrethrum is a perennial herbaceous plant endemic to the eastern coast of the Adriatic Sea, and introduced in large areas of nearly all continents, where it is cultivated for the industrial extraction of pyrethrins. Pyrethrins are a group of six closely related monoterpene esters, widely used as natural insecticides. The world production of natural pyrethrins is lower than the market demand, and a wider introduction of this crop within the Mediterranean agrosystems could be an appealing opportunity for farmers and manufacturers. The availability of adequate amounts of selected plant material to bring into cultivation is, however, one of the major issues. Therefore, the in vitro propagation …

Following their evolutionary process, many plants have oriented their secondary metabolism towards the production of complex molecules, which often show an apparent protective function against pests (insects, fungi, viruses, but also competing plants). The identification and the study of such compounds could play a significant role in the frame of the development of new techniques for sustainable plant protection, where they could help in achieving the goal of a reduction in the use of the most highly-impact chemicals. The Mediterranean basin, with its very large biodiversity, represents a huge reservoir of highly promising plant material, which is scarcely explored as far. Indeed, prelimin…
