title: [Study on the characterizations of genus Curcuma plants on the strains of C. longa L. and C. aromatica Salisb preserved at Izu station of NIHS].
abstract: To clarify the characteristics of genus Curcuma plants, we studied the properties of six strains of Curcuma longa L. and two strains of C. aromatica Salisb. preserved at Izu Experimental Station for Medicinal Plants of National Institute of Health Sciences. Six strains of C. longa were classified into three types according to morphological characteristics, rhizome production, and differences in curcuminoid content of rhizome. The curcuminoid content of the rhizomes in each strain ranged from 2.20 mg/g to 55.23 mg/g. Strains showing a high curcuminoid content had a low rhizome yield. No difference was observed between two strains of C. aromatica in terms of morphological characteristics. C. longa can be easily distinguished by differences in the development of tuberous roots and the color of the rhizome cross section.
