조경식물인 금낭화, 돌단풍, 할미꽃, 붉은잎동자꽃, 벌개미취의 개화기 예측에 필요한 적산온도를 구명하였다. 경기도 수원시에 위치한 국립원예특작과학원에서 2013년 3월 시험포에 식재된 관상식물 5종을 채취하여 컨테이너(30×30×30cm)에 원예용 상토를 이용하여 식재하여 시험포와 온실에 4반복으로 배치하였다. 1주일 간격으로 개아기, 전엽기, 개화기를 조사하였으며 온도를 측정하였다. 온실과 시험포의 적산온도의 비교 결과 조경식물 5종의 생육단계에 따른 적산온도는 금낭화 개아기 176.3±9.12℃, 전엽기 265.1±47.63℃, 개화기 476.1±112.43℃, 돌단풍 개아기 170.0± 32.56℃, 전엽기 352.8±176.84℃, 개화기 452.3 ±17.74℃, 할미꽃 개아기 152.0±7.17℃, 전엽기 266.2 ±54.36℃, 개화기 410.4± 41.58℃, 붉은잎동자꽃 개화기 186.1±22.92℃, 전엽기 205.8± 16.92℃, 개화기 1426.6±135.99℃, 벌개미취 개아기 163.5±9.02, 전엽기 190.6±4.55, 개화기 2714.9±88.97로 나타났다.
This study evaluated the accumulated temperature necessary to predict the flowering time of Dicentra spectabilis (L.) Lem., Mukdenia rossii (Oliv.) Koidz., Pulsatilla dahurica (Fisch. ex DC.) Spreng., Lychnis x arkwrightii, and Aster koraiensis Nakai. Plants were collected from experimental field located at the National Institute of Horticultural and Herbal Science in March 2013. They were transplanted in a container (30×30×30cm) filled with horticultural mix and arranged outdoors and in a greenhouse with 4 repeated sections. To determine the accumulated temperature for each growth stage, we measured the sprouting, foliation and flowering date every week and experimental site temperature also recorded. On averaging the accumulated temperature in a greenhouse and outdoors, these of 5 landscape plants according to the growth phase were as follows; For D. spectabilis, 176.3±9.12℃ at sprouting, 265.1±47.63℃ at foliation and 476.1±112.43℃ at full bloom; for M. rossii, 170.0±32.56℃ at sprouting, 352.8±176.84℃ at sprouting and 452.3±17.74℃ at full bloom; for P. dahurica, 152.0±7.17℃ in sprouting, 266.2±54.36℃ at sprouting and 410.4±41.58℃ in at full bloom; for L. cognata, 186.1±22.92℃ in sprouting, 205.8±16.92℃ at sprouting and 1426.6±135.99℃ at full bloom; and for A. koraiensis, 163.5±9.02 in sprouting, 190.6±4.55 at sprouting, and 2714.9±88.97 at full bloom.
