THE FIRST REPORT OF POLYCARPIC GENOTYPE IN GALBANUM (FERULA GUMMOSA) POPULATIONS

Ferula gummosa Boiss. (galbanum) is recognized as a monocarpic species according to the available data. Following off a research on Iranian galbanum accessions diversity, we found some genotypes that are not monocarpic. The clung parts of the older roots behind the fresh roots, represented the existence of two or three generations of growth in wild populations of galbanum. These polycarpic genotypes were transferred to pots and established in greenhouse conditions. The domesticated plants showed unlimited regeneration power. About ۱۰ to ۱۵ lateral meristematic buds were produced on the roots of this genotype. The vegetative meristematic buds were planted on different rooting media as fine sand and soil. Also these buds were cultured on MS medium for micro propagation. Here we report the existence of polycarpy in some genotypes of galbanum for the first time. This is very important finding which can help to propagate this species with seed production limitation and consequently in conservation of species in nature.
