Age of planted Echinacea purpurea, the factor of seed yield and quality

Results for yield and quality of Echinacea purpure seed obtained from age of plants one, two, three, four and five years are presented. In the laboratory experiments germination energy (GE), total germination (TG), and seed weight was examined. The highest yield of seed was achieved in three-year Echinacea purpurea plants, and the lowest yield was achieved in one-year plants. Age of planted established influence significant on total germination. This parameter the highest of seed in three-year plants and the lowest of seed in five-year Echinacea purpurea plants. The highest of germination energy of seed established for the seed deriving from three-year Echinacea purpurea planted, and the lowest in one-year plants. The absolute mass of seeds the highest in one-year plants, and the lowest for the seed deriving from five-year Echinacea purpurea planted.
