A semi-greenhouse experiment with field grown soybean (Glycine max L. cv Deawon, Uram, Jinpong, Soyon, Pungsangnamul, and Haewon) was performed in 2018. The experiment was aimed to investigate individual impacts of drought stress on soybean characteristic and seed yield. The three treatments were us...

콩은 무엇인가? | 콩[Glycine max (L.)]은 기름과 단백질 함량이 높은 작물로서 여름을 대표하는 밭작물 중의 하나이다. 우리나라의 콩의 개화기와 착협기는 7월 하순에서 8월 중순 사이이다. | |
콩의 생식 생장 단계에서 한발이 미치는 영향은? | , 2019). 한발은 주경장과 주경 마디 수를 적게 하고, 화아분화기에서 개화기까지에는 낙화가 많아지고 결 협률을 저하를 시킨다(Wijewardana et al., 2018). 한 발은 잎에서 협으로 진행되는 탄수화물 동화 작용이 감소하여 질소와 엽록소 함량이 감소시키며(Liu et al., 2004; Ergo et al., 2018), 동화 작용과 뿌리에서의 양분 흡수를 나쁘게 하여서 약 24-50%의 수량을 이루게 한다(Bashir et al., 2019; Gavili et al. | |
한발에 의한 작물 수량 감소의 3개 메커니즘은 어떤 것인가? | , 2013). 한발에 의한 작물 수량 감소는 3개의 메커니즘으로 1) 군락 광합성 효율 감소, 2) 유효 광합성 감소, 3) 수확 지수가 감소 하였다(Earl and Davis, 2003). 또한 수분 스트레스는 식물체의 팽압, 증산작용, 기공 전도도 그리고 물 효율 능력을 감소시킨다(Mutava et al. |
