Sucker is a special non-green slender stem branch which arises from underground base of an erect shoot or crown. It grows horizontally in soil and ultimately comes out to form a new aerial shoot or crown. The process is repeated. Each sucker has one or more nodes with scale leaves and axillary buds, e.g., Chrysanthemum. Curcuma domestica and Zingiber officinale both are the examples of rhizomes.
