Poa genus has a high value for grazing and forage conservation concerning the livestock. In order to study the impacts of cold temperature and Growing Degree Days (GDD) on seedling morphological trait and phonological development of two species involving Poa pratensis and Poa trivialis, this research was conducted in laboratory and greenhouse and outdoor of […]
Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate […]
