| 【Objective】Amomum villosum Lour. is a superior product of Chinese medicine “fructus amomi”, with
a long application history on clinical. The study was to provide references for the variety identification and production as well
as planting through systematical analysis on the characters of local A. villosum variety Reke 2. It is recorded that Yangchun
area of Guangdong is genuine producing area of A. villosum. The quality and pharmaceutical effect are affected by the mixed
provenance, so it is urgent to strengthen the researches of selecting and improving of high quality resources.【Method】
The plant, flower, fruit and other characters of Reke2 were investigated and compared.【Result】The results showed that
the plant of Reke 2 was tall and strong, with the plant height of 2.84 m and stem diameter of 13.12 mm. The leaves were
large and thick, with the leaf length of 43.52 cm and leaf width of 6.46 cm. The leaf margin had no obvious fluctuation,
with protruding line paralleling to the principal vein. The ligule was long elliptic and brown, with a length of 0.95 cm. The
inflorescences showed a “curved type”, with the pedicel length of 9.70 cm, floret number of 9.3 pieces and labellum of 2.24 cm long and 2.39 cm wide. The midrid was yellow and purplish red, with the yellow tip being epitaxial and the purplish red
base being eight-shaped scabbed spots. The fruit was oblate and brown, with 23.2 seeds, 1 000-kernel weight of 14.14 g and
volatile oil content of 3.6%. The flowering period and fruit maturation period of Reke2 were later than those of other varieties.
【Conclusion】The characters of Reke2 were identified through investigation and analysis. As one of the standard varieties
of the DUS testing guidelines, it will lay a foundation for the accurate identification of such variety and selection as well as the
protection and selection of superior A. villosum resources. |
