Ex situ (in field) conservation of Bulgarian species from genus Mentha maintained in the collection of IPGR-Sadovo

The genus Mentha belongs to the botanical family Lamiaceae. In Bulgaria are spread 6 varieties and numerous natural hybrids. The species from the genus Mentha are been well known since ancient days as oil and honey bearing plants. That is why it is considered that most of the known nowadays species are very old. In the Institute of Plant Genetic Resources – Sadovo are maintained in field two Mentha varieties. M. arvensis L and M. spicata L. Besides the in field conservation of the species, in vitro techniques are a reliable means of reproduction and long-term storage. In the experimental work for in vitro conservation of microcuttings of M. arvensis L and M. spicata L in low temperatures were applied 4 different temperatures - 2ºС, 4ºС, 6ºС and 8ºС. Longest conservation period (12 months) with highest level of survived cuttings (83,50%) was observed in 4ºС. After cultivation of the newly obtained microcuttings from in vitro conservation in normal conditions (24ºС) were observed little differences between two mint varieties  in shoot growth, which is due to their specific biology and the period of in vitro conservation under 4ºС has no influence
