THE ALTITUDINAL CLIMATICAL AND PHENOLOGICAL CLASSIFICATION OF VERBASCUM L SPECIES FROM DIFFERENT PHYTOGEOGRAPHICAL REGIONS OF TURKEY

İngilizce (OpenAlex)

The Verbascum L. Group A with 4 stamens (30 taxa) were grouped which encompass ecological range, climatic specificity (temperature and precipitation), altitude and phenology (flowering and seed bearing periods) in Irano-Turanian, East Mediterranian and Euro-Siberian phytogeographical regions in Turkey.For this purpose Single Linkage (Nearest Neighbour) Hierarchical Cluster method was used.The results of cluster analyses suggested that the plant species which were collected from Irano-Turanian, East Mediterranean and Euro-Siberian regions might be divided into three groups with respect to 5 characteristics based on cophenetic correlation, Delta coefficient, the pooled standard deviation of all the variables forming the cluster (RMSSTD) and determination coefficient (R 2 ).Pearson correlations were also computed in order to investigate linear relations between the phenological characteristics of regions.It was observed that there was a negative relation between temperature and flowering time (r=-0.678;p=0.008), temperature and seed bearing time (r=-0.657;p=0.011) in Irano-Turanian region.However, the correlation between temperature and flowering time (r=-0.096;p=0.767) and temperature and seeding time (r=0.176;p=0.584) was not statistically significant for the East-Mediterranean region.
