Delay of budding and growth inhibition of the reed Phragmites australis caused by reaping of withered stems and submergence of the cut ends [in Japanese]

FUJIWARA KOH-ICHI

… When the cut ends of withered stems were flooded in spring, growth of new shoots was inhibited probably because of limited oxygen supply to the rhizomes. … As an adaptation, the reeds rapidly extended shoots to the water surface to obtain oxygen. … However, it was thought that this adaptation would not function easily in natural lake areas because these shoots were easily damaged by wind and waves. …
