Abstract: phenology has emerged recently as an important focus for ecological research .The research has performed in selected plots of Guilan Province, in the North of Iran. The each selected plot area is one hectare. We selected 6 plots of hornbeam trees from 480 to 1170 meters above sea level were determined in mountainous region .This study was performed on different altitudes and different aspects .the six sample plots were selected in study area. Phenological studies were fulfilled during four years as from January 2003 to December 2006 trees by using ground observations and IRS1C/1D - LISS-IIÉ data in each plot. The statistical analysis One (Way-ANOVA) showed that there were significant differences between the phonological characteristics in respect to the different site physiographical characteristics. Furthermore there were significant negative correlation between average precipitation and average air temperature and there of the phonological characteristics. The co!
rrelation between average air temperature and leaf mature and fall date was significantly negative .Appearance of flowers has usually been begun in this species at the same time of Leaf appearance and from its beside, in such as a way that it continues as from the first of the third week of April and will continue up to first week of May. Leaves in this species complete usually 15 to 20 days after germination .Fruits mostly become ripe about 70 days after appearance meaning as from the first of the second week of November up to the end of the third week. Leaves in this species begin to fall as from the beginning of the fourth week of November and will continue up to the end of first week of December and sometimes up to the end of the first half of the December, too. The green-up of vegetation has advanced in the spring by 1.2 days yr_1 and the dormancy delayed in autumn by 0.6 days yr_1.The results show that over the study period, the growing season duration has lengthened !
by 1.8 days yr_1 in study region.
