Abstract

The artificial seed technology is one of the most important tools to plant scientist working with in vitro cultures. Encapsulation can provide a source of aseptic explant material that can be used if stock plants or in vitro cultures become infected with microorganisms. Moreover, the application of artificial seeds allows to maintain gene collections, which cannot be stored in liquid nitrogen. Up-to-date several studies on 13 Asteraceae genera were performed. It was found that synthetic seeds are suitable for medium-term storage under refrigeration conditions; however, long storage periods often lead to viability loss. The composition of the ideal gel matrix depends on the species and explant type. In general, however, the artificial endosperm should be supplemented with Murashige and Skoog (1962) salts and sucrose for in vitro germination. As for the recovery medium, the presence of benzyl adenine is beneficial. Also direct sowing of synseeds to ex vitro conditions is possible, provided that the artificial endosperm does not contain any organic compounds. The performed studies confirmed the stability of plants recovered from artificial seeds on the genetic, cytogenetic, biochemical, and phenotypic levels. Further research should be carried out to standardize optimum storage technique for better results and to prolong the artificial seeds viability.
