Abstract

A field experiment was conducted to determine the optimal transplanting date for 'Sukwang', a high grain quality japonica rice, in the southwestern plain area in South Korea. 25-day-old seedlings were transplanted four times by 15 days interval on May 16, June 1, 16, and 30 in 2013 and 2014. Heading dates were August 12 and August 29 in the first and the last transplanting, respectively. Ripening ratio was highest in June 1 and June 16 plots at range of 93 - 94%, and was lowest in 16 May plot. Milled rice yield was the highest in June 1 and June 16 at rage of 538 - 555 kg/10a, and was the lowest in May 16. Head rice yield showed same tendency to milled rice yield. Protein content was not significantly different among treatments except June 1, however, it was slightly increased in the later transplanting plots. Amylose content was increased in the later transplanting plots. According to the regression curve of transplanting dates and grain yield, the optimal transplanting date of 'Sukwang' was June 10 in the southwestern plain area in Korea.

남부 평야지에서 최고품질인 중만생종 '수광' 품종의 적정 이앙시기를 구명하고자 5월 16일, 6월 1일, 6월 16일, 6월 30일에 4회 이앙하여 이앙시기별 벼 생육, 수량구성요소, 수량 및 품질 관련형질을 검토한 결과를 요약하면 다음과 같다. 1. 이앙시기별 출수기는 이앙시기가 늦을수록 출수기도 늦어졌으나 5월 16일 이앙은 8월 12일, 6월 30일 이앙은 8월 29일로 안전출수기 이내에 출수되었다. 2. 등숙비율은 6월 1일과 6월 16일 이앙에서 93 ~ 94%로 가장 높았고 5월 16일 이앙에서는 87%로 가장 낮았다. 3. 쌀수량은 6월 1일과 6월 16일 이앙에서 538 ~ 555 kg/10a로 수량이 높고 6월 30일 이앙, 5월 16일 이앙 순이었고 완전미수량은 쌀수량과 비슷한 경향이었다. 4. 단백질함량은 이앙시기에 관계없이 큰 차이를 보이지 않았지만 늦게 이앙할수록 증가하는 경향이며, 아밀로오스 함량도 이앙시기가 늦을수록 증가하였다. 5. 따라서 '수광'의 이앙적기는 쌀수량, 완전미수량 및 품질 등을 고려해 볼 때 남부 평야지에서는 6월 10일 경에 이앙하는 것이 바람직 할 것으로 판단되었다.
