Size of the Inflorescence

The range in the diameter of the disk flowers in the inflorescence was 1.3 to 1.8 cm (S wanton, 1986). The inflorescences can be separated into size categories (e.g., large, medium, and small) (Pas ko, 1973). 

The number of inflorescences per plant was separated into three classes — small (1 to 15), medium (16 to 49), and large (50 to 155) — which varied between early and late clones and with the number of branches (Pas ko, 1973). Swanton (1986) found a range of 6 to 78 inflorescences per plant among clones from different ecological niches the range in dry weight was also substantial (i.e., 2 to 17 g per plant). The number of flowers also varies with production year and growing conditions (Tsvetoukhine, 1960).
