When 10-15, 20-25, 30-35, 40-45, 50-55, and 60-65 g of fresh one year old rhizomes of Atractylodes ovata were used for sitting, heavier total dry weights of two year old plants were obtained from heavier one year old rhizomes, but the one year old rhizomes for sitting had apparently no effect on dry weights of rhizomes and roots of two year old plants. The dry weight of head flowers accounted for 40 to 50% of the total dry weight of two year old plants, and those of rhizomes accounted for 15 to 20%. Flower- and bud-picking encouraged the thickening of the rhizomes of two year old plants. Bud-picking was the more effective : the rhizome weights were heavier by 1% than the rhizomes of flowering plants and flower-picking plants in all experimental plots. The essential oil contents of two year old rhizomes of flowering plants were not significantly different from those of bud-picked plants. However, dilute ethanol extracts of bud-picked plants were higher than those of flowering plants by 5% level.
