Abstract

Studying the phenological stages is one the important factors affecting the time of livestock entry to and exit from rangelands. In addition, the best time for seed collection, nutritional value and range management depend on studying the phenological stages. In this study, phenological stages of 10 range species in Saraliabad-e-Gorgan region were investigated for four years (2007-2010). The longitudinal growth and phenological stages of the study species including vegetative, flowering and seeding stages as well as plant dormancy period and autumn regrowth were recorded. The results of Phenology showed that in early June most grasses were at the heading stage and most forbs were at the flowering stage. Therefore, range readiness for livestock entry to the rangeland is in early June with the difference that in wet years, it will be 10 days and one to two weeks later in plain and mountainous areas, respectively. Among the study grasses, Agropyrum intermedium and Agropyrum trichophorum, and among the forbs Medicago sativa reached the flowering stage and seed formation later. The best time to collect the seeds of most grasses is in the middle of July, except A. intermedium and A. trichophorum, which is in mid-September. Early June was the best time to collect the seeds of forbs like Trifolium repens and Medicago lupulina. For Centaurea zuvandica and Medicago sativa mid-July and late July were the best times for seed collection, respectively.
