Atractylodes lancea (Thunb.) DC was divided into four kinds of types, the incised, ovate, long lanceolate and short lanceolate, according to leaf morphology. CI-600 Root Scanner System was use to continuously detect the root system via Minirhizotrons. The results obtained from Minirhizotrons method showed that the roots growth in the incised Atractylodes lancea was fastest among the four types, and that in the short lanceolate Atractylodes lancea slowest. The roots growth of the incised Atractylodes lancea in the whole year was up to 73.9%, and that from March to May up to 51.2%. The roots growth of the short lanceolate Atractylodes lancea in the whole year was only 31.2%, and that from March to May only 5.9%. It can be seen that the elongation growth of underground parts of Atractylodes lancea had significant differences among the four types based on cell image analysis. The elongation growth of rhizome and fibrous roots of the incised Atractylodes lancea was fastest, and there was no significant difference among the ovate, long lanceolate and short lanceolate Atractylodes lancea. The fibrous roots elongation growth in the incised Atractylodes lancea was up to 57.2% Thus, it may be inferred that the rapidly increasing in root growth of Atractylodes lancea took place during the March and May, and the major growth pattern was cell elongation. Those results would provide the basis for the selection to superior variety and harvest time of Atractylodes lancea.
