Colchicum L. is a herbaceous perennial that produces imposing pink, white, yellow and purple flowers and at the same time from whose seeds and bulbs colchicine is obtained.
The aim of this study was to determine the adaptation ability of all Colchicum L. species in open field conditions Yalova/Turkey.
All the regions of Turkey were analyzed between 2006 and 2009 and 47 species (49 taxa), 36 of which are endemic out of 384 populations were determined. 10 bulbs representing each population were collected and planted in flower pots with soil mixtures of 8 unit forest soil + 4 unit turf + 1 unit river sand + 1 unit perlite + slow release fertilizer.
All morphological (size, shape, color and number of plant, leaf and flower) and phenological features (date of flowering, flower longevity, flowery vegetation period, date of seed maturation), were recorded every other day to specify through observation.
The least and the most values of the received 2 year repeated data on the basis of species and population were detected and their adaptation capacity has been specified.
As a result of the study, when blooming is considered as a main adaptation criteria, only one species (C. paschei) from the 47 Colchicum species did not bloom, yet other species bloomed and adapted to open field conditions in Yalova.
