Florist's cyclamen; Roots (Botany)--Physiology; Roots (Botany)--Growth
The primary body of the root of Cyclamen persicum Mill. is described. The rootcap consists of two components of separate origin. Cells of the columella are derived from the dermatocalyptrogen by periclinal wall formation. Further growth of the columella is due primarily to the increase in size of existing cells. Cells of the lateral rootcap arise from the protoderm by periclinal wall formation. Continued growth in this region is due to both increase in cell number and increase in size of existing cells. Proximal to the dermatocalyptrogen is the presumptive quiescent center. Around the periphery of this zone are located the initials of the ground meristem and procambium.
