Abstract

This study was carried out in 2014 and 2015 to investigate the effect of transplanting density on panicle production and to analyze the relationship of panicle production with yield traits in the mid-maturing quality rice cultivar 'Haiami' in the mid-plain area of Korea. Number of tillers per square meter increased by reducing planting distance and increasing seedling number per hill. These effects were maintained until maturity and were reflected in the final number of panicles per square meter, although the effect of planting density decreased as rice growth progressed. However, increased panicle number per square meter following dense planting did not improve head rice yield. Panicle number per square meter was negatively associated with spikelet number per panicle and was not correlated with other yield components or head rice yield. Head rice yield was not correlated with head rice percentage but was closely and positively correlated with milled rice yield. Milled rice yield did not increase with grain filling percentage but increased with spikelet number per square meter. Spikelet number per square meter increased with both spikelet number per panicle and panicle number per square meter, although the former had a greater influence. Therefore, we conclude that head rice yield of the 'Haiami' cultivar grown in the mid-plain area of Korea is not improved with an increased panicle number following high planting density but it could be improved with high milled rice yield by increasing spikelet number per unit area.

중부 평야지에서 최고품질 중생종 벼 '하이아미'의 밀식에 의한 수수 증가 효과와 그에 따른 수량구성요소 및 수량성 변화의 관계를 분석하고, 완전미 수량에 대한 수량 관련요소의 상대적 중요도를 평가하기 위하여 국립식량과학원 중부작물부 수원 벼 재배시험 포장에서 2014~2015년 수행한 연구 결과는 다음과 같다. 1. 단위 면적당 경수는 재식거리가 좁고 주당본수가 많을수록 증가하는 경향이었는데, 벼 생육이 진전됨에 따라 그 차이는 적어졌으나 이러한 경향은 수확기 수수까지 유지되었다. 2. 완전미 수량은 재식거리에 따라 2014년에는 유의한 차이가 없었고 2015년에는 $30{\times}18cm$에서만 감소하였으며, 두 해 모두 주당본수가 적을수록 높았다. 3. 단위 면적당 포기수와 주당본수 증가에 의하여 $m^2$당 수수는 많아졌으나, 밀식에 의한 수수 증가가 완전미 수량에는 영향을 미치지 않았다. 4. 단위 면적당 수수는 수당영화수와만 부의 상관을 나타내었고, 다른 수량구성요소 및 완전미 수량과 유의한 관계를 보이지 않았다. 5. 재식거리와 주당본수 조절에 의한 완전미 수량의 변화는 완전미 비율과는 관계가 없었고 쌀수량과 직선적인 정의 상관을 보였으며, 쌀수량은 $m^2$당 영화수 증가에 따라 향상되었는데, $m^2$당 영화수는 $m^2$당 수수보다 수당영화수 증가의 영향을 크게 받았으나 이들 두 요소가 함께 영향을 미쳤다. 6. 결론적으로 중부 평야지에서 하이아미를 보통기 보비 재배하는 경우, 완전미 수량은 밀식에 의한 수수 증가로 향상되지 않으며, $m^2$당 수수와 수당영화수의 적절한 조합에 의하여 $m^2$당 영화수를 증가시켜 쌀수량을 증대시킴으로써 높일 수 있는 것으로 분석되었다.
