土壤水分 差異가 율무의 生長과 通氣組織 發達에 미치는 影響

Effects of different water potential on the growth and aerenchyma development of Adlay(Cojx lacryma-jobi L. var. mayuen) were studied under every 3 days intermittent irrigation as a control at different growth stages, flooded pot condition and drought. Adlay could not germinate in the anaerobic soil conditions with excessive moisture while it wasn’t inflicted with moisture damage after sprouting. Sprouted adlay can grow under flooded soil moisture condition because it’s root has orthostichy cell, ventilating structure and cortex. Proping or ventilating roots were generated from adlay grown under flooded pots. Drought damage inflicted at the heading stage was the most severe.
