Sažetak
Dati su rezultati ispitivanja prinosa i kvaliteta semena ehinacee sakupljenog sa zasada starog jednu, dve, tri, četiri i pet godina. Pored ukupne klijavosti (UK) ispitivane su i energija klijanja (EK) i masa semena. Najveći prinos semena ostvaren je na zasadu starom tri godine, a najmanji na zasadu starosti jedne godine. Starost zasada imala je značajnog uticaja na ukupnu klijavost, tako da je ovaj parametar bio najveći kod semena sa trogodišnjeg zasada a najmanji kod semena sa petogodišnjeg zasada. Najbolju energiju klijanja imalo je seme trogodišnjeg zasada, a najslabiju jednogodišnjeg. U pogledu apsolutne mase seme jednogodišnjeg zasada imalo je najbolju vrednost, a najslabiju seme petogodišnjeg zasada.
Abstract
Results for yield and quality of echinacea purpurea seed obtained from age of plants one, two, three, four and five year are presented. In the laboratory experiments germination energy (GE), total germination (TG) and weight seed 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 parametar 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.
