Abstract
본 연구는 남부지역에서 주요 콩 품종의 파종기 이동이 생태반응과 생육 및 수량성 등에 미치는 영향을 구명하고자 전남 나주(위도 $35^{\circ}$ 04'N, 경도 $126^{\circ}$ 54'E)에서 2008년부터 2010년까지 3개년간 수행되었다. 여름형콩 품종인 새올콩과 다원콩, 가을형콩 품종인 태광콩, 풍산나물콩 및 청자3호를 이용하여 5월 15일, 5월 30일, 6월 15일, 6월 30일, 7월 15일에 파종하였다. 1. 여름형콩 품종 중에서 새올콩은 다원콩에 비해 파종기 지연에 따른 개화일수와 등숙일수 및 생육일수의 짧아지는 정도가 적었다. 2. 가을형콩 품종 중에서 태광콩의 생식생장기 일장반응은 풍산나물콩이나 청자3호보다 낮은 편이었다. 반면에 풍산나물콩과 청자3호의 영양생장기와 생식생장기 일장반응은 기타 시험품종보다 높았고, 그 경향은 풍산나물콩이 더 컷다. 3. 경장, 주경절수 및 주경두께는 대부분 시험품종에서 늦게 파종할수록 감소하는 경향이었으나, 새올콩의 경장과 주경절수는 유의차가 없었다. 4. 여름형콩 품종인 새올콩과 다원콩의 제1착협절위와 모든 시험품종의 절간장은 파종기를 달리하여도 유의차가 없었다. 5. 개체당 협수는 새올콩을 제외한 모든 시험품종에서 파종기가 지연됨에 따라 감소하는 경향이었는데, 소립종인 다원콩과 풍산나물콩에서 변이가 크고, 특히 가을형콩 품종인 풍산나물콩이 더 컷다. 6. 수량은 다원콩과 태광콩 및 풍산나물콩 5월 30일 파종, 청자3호 5월 30일과 6월 15일 파종에서 가장 많았다. 새올콩의 수량은 5월 30일부터 7월 15일 파종기간 유의차가 없고 5월 15일 파종에서 가장 낮았다. The purpose of this study was to investigate the effects of shifts in sowing time on the ecological responses, growth and yields of major soybean cultivars in a southern region of South Korea. Experiments were carried out in Naju, Jeonnam Province (latitude $35^{\circ}$ 04'N, longitude $126^{\circ}$ 54'E) for three years from 2008 to 2010. The test cultivars included Saeol-kong and Tawon-kong of the summer type, Taekwang-kong and Pungsannamul-kong, and Cheongja3 of the autumn type. Sowing took place on May 15 and 30, June 15 and 30, and July 15 of each year. Of the summer type soybean cultivars, Saeol-kong showed a smaller curtailment in days from sowing to flowering, days from flowering to maturity, and days from sowing to maturity according to sowing time postponement than Tawon-kong. Of the autumn type soybean cultivars, Taekwang-kong exhibited a lower photoperiodic response in reproductive growth period than Pungsannamul-kong and Cheongja3, both of which recorded higher level photoperiodic responses in vegetative growth stages and reproductive growth periods than other test cultivars, with the former exhibiting higher levels than the latter. Most of the test cultivars tended to decrease in stem length, node numbers of the main stem, and stem diameter according to postponed sowing time, but there were no significant differences in stem length and node numbers of the main stem of the Saeol-kong cultivar. Differences in sowing times did not affect the first setting pod node order of Saeol-kong and Tawon-kong summer type cultivars of internode lengths of all of the test cultivars. All of the test cultivars tended to show decreases in pod number per plant due to postponement of sowing time except for the Saeol-kong cultivar. The variation was more prominent in small grain cultivars such as Tawon-kong and Pungsannamul-kong with the latter autumn type cultivar showing especially large variation. Yields were the greatest for the Tawon-kong, Taekwang-kong, and Pungsannamul-kong cultivars sown on May 30 and Cheongja3 sown on May 30 and June 15. There were no significant differences in the yields of Saeol-kong for different sowing times from May 30 to July 15, with the yields lowest for the batch sown on May 15.
