tailieunhanh - Pollination behaviour of Linum aretioides Boiss. (Linaceae) and its relations with air temperature and humidity

Linum aretioides Boiss., a local endemic, is distributed only on 2 mountains (İzmir: Bozdağ; Denizli: Babadağ) at the western part of Turkey between 1630 and 2300 m altitudes, above the tree line. The studies were conducted on Mount Bozdağ above the ski complex between 1750 and 2150 m, and on Mount Babadağ between 1630-2300 m both located at subalpine zones. | Research Article Turk J Bot 34 (2010) 355-365 © TÜBİTAK doi: Pollination behaviour of Linum aretioides Boiss.

The studies were conducted on Mount Bozdağ above the ski complex between 1750 and 2150 m, and on Mount Babadağ between 1630-2300 m both located at subalpine zones. Four 8 × 8 m quadrats on Bozdağ and 5 on Babadağ were used for the experiments. The development of reproductive structures of plants and frequency of insect visits were observed from early May to late June in 2006 and 2007. Blooming and pollination periods terminated by the last week in May on Babadağ and by the second week in June on Bozdağ. Temperatures below 10 °C before these periods appear to affect the activities of main pollinators, such as bees and butterflies, resulting in a decline in pollination, and eventually in seed formation. In Bozdağ, the average relative humidity values at 1000 hours, when the insect activities were the highest, were ± in June 2006, ± in May 2007, and ± in June 2007. The corresponding values on Babadağ were ± , ± , and ± , respectively. The most effective species in pollination process were butterflies, in particular Pieris brassicae.
