Rhizome is an underground modification of the stem. It is fleshy, non-green underground stem. It has distinct nodes and internodes. The nodes bear dry scale leaves with axillary buds. Terminal buds also present. Adventitious roots arise from the lower side. The rhizomes that grow obliquely is called root stock rhizome and when they grow horizontally is called straggling rhizome. Example, ginger, turmeric, etc. Suckers are subaerial modifications of the stem. It arises from the basal, underground part of the main stem. It grows horizontally for a distance under the soil and then emerges obliquely upwards. It develops a leafy shoot and adventitious roots before separating from the mother plant. The common sucker-bearing plants are Chrysanthemum (Or. Sebati), Musa (banana), Mentha (Or podina), strawberry, pineapple etc.
