Adventitious buds are

Adventitious buds are

• A. The main terminal buds at the end of a limb.
• B. Subnormal buds along the stem that can lead to epicormic branches.
• C. Buds that only appear after fire.
• D. Fruiting bodies of fungi.

Answer: (B)

Adventitious buds form in unusual places on a plant, not at the usual leaf axils or the tip of a stem. They can arise along stems, roots, or damaged tissue and lie dormant until conditions trigger them to grow. When they activate after stress, they can produce shoots called epicormic branches. So a description that highlights buds along the stem that are not in the normal position and that can give rise to epicormic branches captures the essence of adventitious buds. In contrast, the terminal bud at the end of a limb is an apical bud, not adventitious; buds that appear only after fire describe a specific stress response but don’t define adventitious buds themselves; and fruiting bodies of fungi are not plant buds at all.
