Abstract:
OBJECTIVETo study the seed quality of Achyranthes bidentata from different sources and establish a standard of seed quality grading.
METHODSeed weight and moisture content determination, germination test, purity analysis were carried out by 100 grains method, high-temperature drying, double deck filter paper and GB/T354. 3-Seed Testing for Crops methods respectively. Eight collections were planted in several field plots.
RESULTThe 1 000 grains weight of 33 collections is 0.69 to 3.54 g with a variance coefficient 24.83%, the germination rate between 19.02% to 99% with a variance coefficient 38.24%. Seed moisture content and purity showed no significantly difference. K-means cluster analysis showed that 33 collections were divided into 3 grades: the first grade including 23 collections, the second and third grade including 5 collections respectively. Eight collections showed different field growth and yield characters.
CONCLUSIONThere are significant differences in seed quality of A. bidentata, so the classification management is needed in medicinal materials market. Germination test is an effective method before cultivating.
