This study has stored Pulsatilla dahurica (Fisch. ex DC.) Spreng. seeds, which is known to be short in storage life, in various temperatures for one year to observe the changes in germinability and anticipated the appropriate storage temperature by performing accelerated aging experiment. Seeds for storage were collected in Andong-si, Gyeongsangbuk- do, late May 2020 and were sealed in plastic bag after the cleaning and stored in ‒20, 4, and 25°C chamber for one year. Control seeds used for Saturated Salt Accelerated Aging (SSAA) test was collected in early June 2021 at the same place. Each seed had measured of their sizes, weight of one thousand seeds, moisture content, E:S ratio, viability, and 4 weeks of initial percent germination, after the collection. SSAA test was performed using aging tray installed seed testing container with 40mL of saturated salt solution (NaCl). Seeds were aged for 72h at 41 and 47°C then their viability was measured with TZ test and were incubated in the chamber. After one year, germinability of stored seeds were measured with their percent germination (PG), start of germination (SG), mean germination time (MGT) and median germination time (T<SUB>50</SUB>) in 25/15°C (16/8h, White-LED, 30 μmol/m<SUP>-2</SUP>/s<SUP>-1</SUP> PPFD/Dark) chamber. As a result, seeds from both lots had E:S ratio of 0.23~0.24 indicating that they are morphologically immature. Initial viability of ... 전체 초록 보기
