| Heteropappus arenarius Kitam., an autumn-flowering biennial belonging to wild chrysanthemums, is found to be native in southeastern coastal area and Jeju island of Korea. It could play a good role for ground cover plants on a large-scale landscape area, especially, barren soil or sloping hillside. This study was initiated to screen optimum germination temperature influenced by local strain and harvesting stage of H. arenarius. The following was the response of seed germination between local strain and temperature. The average of final germination percentage (FG) was the highest in 'Guryongpo' (89.7%) among four local strains, followed by 'Gujwa' (87.3%), 'Gampo' (87.3%), and 'HKNU-I' (71.5%). The average of $T_{50}$ was shorter in 'Gujwa' (3.6 d) and 'Guryongpo' (4.0 d) than the others. The average of FG and $T_{50}$ was the highest as 76.2% and shortest as 3.6 d in $20^{circ}C$, respectively, followed by $30^{circ}C$, $25^{circ}C$, and $15^{circ}C$. In case of 'Gujwa', however, FG and T50 was higher in $20^{circ}C$ and shorter in $15^{circ}C$ than others. In the relationship between harvesting stage and temperature, the average of FG was greatly higher in Stage III (90.7%) and Stage IV (88.6%) than the others including Stage II (35.7%) and Stage I (26.0%). The average of $T_{50}$ was shorter in Stage IV (3.7 d) and Stage III (4.3 d) than the others, which showed less than 50% of FG. Nevertheless, the available range of seed harvesting stage was from Stage I to Stage IV because H. arenarius seeds could germinate at all stages. In conclusion, it was recommended that the optimum temperature and harvesting stage was $20^{circ}C$ and Stage $III{sim}IV$, respectively, for seed germination of H. arenarius. |
