Abstract

 The phenological stage of some important rangeland plants were assessed from 1994 to 1996. The sutdy was conducted in Hanna Research Station of Semirom, Esfahan, Iran. Starting date and duration of the grazing period however were the main objective of the study. Bromus tomentellus and Stipa barbata, Astragalus cyclophyllon, Onobrychis melanotricha and Polygonum domosum and Erutia ceratoeides from the forbs as representative of the shrubs were studied. Ten relatively uniform stands of each species were measured. Annual life cycle of the plants were divided into two periods, more active phase which was from initial growth to anthesis and less active phase from anthesis to maturity. Within the first phase every 15 days, and in second phase every 30 days, data were recorded. Analysis of data shows that physiological and morphological behavior of the species is synchoronized with climatic condition. Also the phenological type that show the start and end of each phenological stage and it's correlation with climatic factors were drawn on amberothermique curve of the station. Livestock entrance and exit, and Suitable grazing period of the range were determined according to the phenological data. It was also concluded that growth period of drought tolerant species such as shrubs are longer than forbs and grasses.
