![]() scolopax and that the orchids studied require urgent conservation action. Our data show that pollinators have a signifi cant role in the fruit sets of D. bifolia in 2 diff erent locations with an average fruit set of 62.7%. scolopax found in nature were signifi cantly higher than those of the control groups (27% compared to 16%, N = 67, P < 0.001 and 10.4% compared to 3.04%, N = 44, P < 0.02, respectively). scolopax from the region, recorded only in a remote location with a population of about 44 plants. Th e distributions of the 5 species were completely fragmented and the population sizes were extremely small. We compared the obtained fruit set values with those reported from other regions. Th e fruit set was recorded for the latter 3 species and compared in natural and control groups (pollinators prevented) for D. Th e distribution and population size of 5 orchid species (Cephalanthera longifolia, Orchis simia, Platanthera bifolia, Dactylorhiza romana, and Ophrys scolopax) were studied in the southern Caucasus based on the individual numbers in a given area. Moreover, suitable management treatments that would increase the light levels within the forest sites studied may also increase the pollination success and the fruit production of the studied orchids. punctulata at the edges of its range is not delimited by factors related to its pollination effectiveness and that other factors, mostly related to the microsite conditions, might play a more significant role in the colonization of more western areas. ![]() The results demonstrate that the distribution of O. purpurea were found to be nonsignificant. punctulata, whereas the respective effects to the individuals of O. Among these factors, the nearest neighbor distance had the highest impact on the pollination success of O. purpurea was not significantly correlated with plant height, inflorescence size, or nearest neighbor distance, these factors were found to be significantly correlated to the pollination success of O. punctulata, whereas both species also had significantly higher fruit set in the grassland compared to the forest. purpurea was significantly greater compared to O. Orchids of Europe, North Africa and the Middle East (3. Yellow form References Delforge, Pierre (2006). ![]() This species is pollinated by the bee Halictus marginatus. purpurea showed a significant differentiation. Orchis galilaea is a species of orchid found from southern Turkey to Israel. ![]() The comparative results of Orchis punctulata and O. The pollination success of two nonrewarding orchids in two coarse habitats was examined. ![]()
