Distribution areas, morphologial and phenologicial characteristics of some native orchid species in Bucak (Burdur) Province

Abstract

In this study, distribution, morphologic and phenologic characteristics of some Orchid species which are used for producing sahlep in Burdur region were determined. Data were obtained from 26 stands of Bucak province where orchids species mostly distributed. As a result of field studies which were conducted in 2015 (March to July) of flower, 13 taxa were found. Morphologic and phenologic measurements such as number, color, stem length and bloom period, plant height, tuber weight, width, length, number and maturation period were made on the studied taxa. The first flowering species is Ophyrs mammosa (beginning of March) and the last ones are Orchis purpurea (mid-April) and Orchis simia (mid-April). Ophyrs mammosa is the first full flowering species (mid-April) and the last taxon is Ophrys reinholdii subsp. leucotaenia (mid-June). The first maturing bump belongs to Ophyrs mammosa (end of April) and the last one to Himantoglossum comperianum (end of July). The stands where the orchids densely occured are the forests openings, steep rocky slopes and edge of cultural areas. Productivity of flower and tuber are the highest on south and south-western aspects. Slopes of these stands varied between 5-40%. Orchid taxa were distributed between 300 and 1451 m.
