초록
단양쑥부쟁이(Aster altaicus var. uchiyamae)는 한국특산식물이자 환경부 지정 멸종위기식물 Ⅱ급으로하천변에 서식하는 식물이다. 본 연구는 지구온난화가 단양쑥부쟁이의 생태적 반응에 미치는 영향을 알아보기 위해 CO2농도와 온도가 상승된 처리구와 대조구에서 종자를 파종하고, 유식물을 키워 발아율, 식물계절학, 영양생장과 생식생장을 관찰하였다. 그 결과, 단양쑥부쟁이의 발아율은 대조구보다 처리구에서 더 낮았다. 처리구에서살아있는 잎의 지속 시기는 대조구보다 더 길었다. 개화와 꽃의 지속 시기, 종자 성숙 시기는 처리구에서 더 느렸다. 지상부와 지하부 무게는 처리구에서 더 가벼웠다. 개체 당 꽃대 수와 꽃대 당 종자개수는 처리구에서 더적었다. 개체 당 꽃대무게, 꽃대 당 종자무게 그리고 종자 한 개 무게는 처리구에서 더 가벼웠다. 이상으로 볼때, CO2농도와 온도상승은 단양쑥부쟁이의 생태에 부정적인 영향을 준다.
Abstract
Aster altaicus var. uchiyamae, endangered plants to grade Ⅱ designated by the Ministry of Environment Korea, is only distributed in Gyeongsangbukdo, Chungcheongnamdo in Korea. In order to know the effects of elevated CO2 concentration and temperature on ecological responses of A. altaicus var. uchiyamae, this study was carried out in the control(ambient CO2 + ambient temperature) and treatment(elevated CO2 + elevated temperature) at glasshouse. As a result, germination rate of A. altaicus var. uchiyamae was higher in control than in treatment. Period of alive leaf was longer in control than in treatment. Period of blooming and seed maturity was faster in control than in treatment. Shoot and root weight were heavier in control than in treatment. No. of inflorescence per plant and seed per inflorescence was higher in control than in treatment. Weight of inflorescence per plant, seed per inflorescence and one seed was heavier in control than in treatment. These results indicate that ecological responses of A. altaicus var. uchiyamae may be more negatively affected by elevated CO2 and temperature except for phenological responses of that may be delayed under future global warming situation.
