GERMPLASM BANK | WHAT AND HOW?

The main mission of the Germplasm Bank of El Botànic is to conserve the endemic, rare or endangered plant species belonging to the western Mediterranean flora, specially, those from the Valencian region. At the same time, other species of systematic, biogeographic or ornamental interest are also collected.

The spores or seeds are collected form natural populations, and an attempt is made to collect the greatest genetic diversity possible. Afterwards the seeds/spores are cleaned and dehydrated to 5% humidity. Under these conditions they are encapsulated in hermetically sealed glass tubes and conserved in a freezing chamber at 25ºC below zero. In this way, great genetic diversity can be conserved in a small space, maintaining the material viable long term, possibly hundreds or even thousands of years.

The work carried out at the Germplasm Bank is not limited to the conservation of seeds and spores; it also performs different tests to establish the viability degree of the samples and establish germination protocols that enable plant populations to be recovered in the event of their becoming weak or disappearing.
