A type of plant stem. Also called a runner or stolon. It grows horizontally from near the ground surface and reproduces vegetatively by producing roots and shoots at a certain distance from the mother plant. In the case of plants such as strawberry and saxifrage, they grow above ground and grow along the ground, so they are a type of stolon, but in the case of Siberian lilies and Japanese yew, they grow underground and run horizontally, so they can be considered a type of rhizome.

植物の茎の一型。走出枝またはランナーrunnerともいう。地表面付近から出て水平に伸び、母体からある程度離れたところで根と芽を出すことによって栄養繁殖の役を果たす。オランダイチゴ、ユキノシタなどの場合は地上に生じて地面に沿って伸びるので匍匐(ほふく)茎の一種であるが、エゾスカシユリ、コヤブランなどの場合は地下に生じて横走するので根茎の一種といえる。 [福田泰二] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
