Recent Topics Posters Rahmanpour, Afsoun [1]. Comparative study of phenology in some species of Juniperus with climatical in Botanical Garden Of Iran. From 1993 to 2002, in the second phase of research and study on phenology of some ornamental trees and shrubs at display section in National Botanical Garden of Iran, 1-5 trees of 8 species and 6 cultivation of Juniperus have been considered. This research includes the following items: Study and annotation on different phases of plant phenology (budding of winter shoot leaf, maturing time of all leaves, flowering time, the maximum time of flowering, end of flowering time, ripening term of seed, permancency time of seed on plant, quantity of seed production, germination percentage of seed, average of annually growth in length and diametric, plantage), PH measurement, humus quantity, percentage of organic and inorganic/mineral materials (clay, silt, sand), soil tissue and aerological graphs. The results shows that the cold air will delay the apperance and maturing time of leaves. So, the maturing time of Juniperus's leaves is longer than decidaous plants and the ripening term of seeds will be long in cold air. Also rainfall influences on phenology changes as it will be sensible in Juniperus during summer and winter days. The mentioned different will be more in four sides during the sun light peak. So, according to the results,it can be determined as well as used in city sites and forest which is based on the occupied surfaces.
