| Abstract:
The tested spice seeds of three origins (I, II, III) were stored for 6 years (Anthriscus cerefolium III) and 20 years (Rumex acetosa I, II, III, Sanquisorba minor I, II) respectively, at +10/30, +5 and –20 °C air-tight in 2 x 100 µ PE bags. The seed moisture content of all seeds ranged from 7,4 to 9,9 %. Germination was tested at temperatures from 10 to 30°C (steps of 5°C). High germination results were found for A. cerefolium (III) seeds after 6 years in all storage variants. Seeds of R. acetosa (II, III) germinated in variant –20 after 20 years to a high percentage at 10 to 25°C. After seven years the germination of seeds of all origins decreased in variant –20 at temperatures 10 and 15°C but later tests revealed an increase. Therefore this pattern indicates a temporary dormancy. For S. minor seeds I and II, high germination results were found in variant +5 after 18 and 20 years at germination temperatures from 15 to 25 °C. | |
