Abstract:   (11090 Views)
Phenology is the study of time and sequence of recurring stages in the life history of an organism. The occurrence fashions of the phenophases form different phenological behavior patterns. Despite the importance of phenology and wide applications of knowing phenophases, few studies have been done on the wooden species in Iran. The goals of this study are identification and designation of the phenophases occuring time and their successions, phenological behavior patterns and finally phenological patterns assay of 35 fruitful and fruitless woody species in the northeast of Esfahan during 2003-2005. Leaves, flowers, fruits, buds, bark and color changes were observed weekly or every other week. Analysis of the obtained charts and tables shows that with respect to the environmental and climatic condition of the area, observed phenological behavior patterns are two- leaf, two-flower and two-fruit emergent patterns two-flower peak patterns three-fruit perpetuity patterns and three leaf shed patterns. Finally, there are three comparative successions, six-flower and three-leaf phenological patterns. Based on the findings, blooming and leaf shed calendars were also achieved.
