Abstract

The effects of short-term waterlogging on physiological responses, fatty acid compositions and yield components of rapeseed at both the vegetative growth and the reproductive growth stages were assessed in this study. Waterlogged plants were treated for a period of 10 days at the vegetative growth stage and 4 days at the reproductive growth stage. The results show that photosynthesis and stomatal conductance at both the vegetative growth and the reproductive growth stage were significantly reduced during the waterlogging period and after the recovery period. When the plants were removed from water, photosynthesis and stomatal conductance progressively restored similar values to those of control plants within $2{\sim}3$ days. Fatty acid compositions were unaffected by waterlogging treatment. However, yield components (pod number and pod length) of the waterlogged treated plants at the reproductive growth stage were significantly reduced. These results suggest that short-term waterlogging may thus influence oilseed yield component.

단기간 침수처리에 의한 유채의 영양생장과 생식생장기의 생리적 반응, 지방산 조성과 수확량에 관하여 조사하였다. 영양생장 단계에서 10일과 생식생장 단계에서 4일 침수한 결과를 영양생장과 생식생 장기 모두 광합성, 기공전도도와 증산량은 침수처리 기간과 회복시기에 현저하게 감소하였다. 침수처리가 끝난 처리구에서 광합성과 기공전도도는 $2{\sim}3$일 내에 대조구와 비슷한 경향을 보였다. 침수처리된 작품의 지방산 조성은 대조구에 비해 통계적 유의성의 차이를 보이지 않았지만 수확량과 관련된 요인들에서 현저하게 감소함으로 생식생장 단계에서의 단기간 침수처리가 수확량 요인에 큰 영향을 줌으로서 종자 수확량에 영향을 미칠 것으로 사료된다.
