Phenology of Veronica beccabungal flowering in NW Iran

Identification of plants distribution honey plants in an area are very important and necessary for the Apiculture and Nectar production plays an important role in the pollination of flowering plants. The aim of this research was determine flowering duration and delay for three plants of Veronica beccabungal family Shanjan Rangeland. This research was conducted in Shanjan Rangeland with elevation between 1600 m to 2050 m with SW aspect in Shabestar district, East Azerbaijan, Iran in spring and summer 2011. For sampling, we used an accidental sampling methodology (1*1 m quadrate) in this research and selected 10 samples in each 8 stations separately. Difference elevation was 55 m between each station. There is about 10.75 days delay for each 110 m elevation deference for flowering start of this plant.
