Effect of Seed Treatments on Germination and Growth of Agrimonia pilosa Ledeb

The experiment was conducted to increase germination of Agrimonia pilosa seeds, one of the natural medicinal plants, by various treatments, and also the effects of seed treatments on the growth of plants after sowing in field. The optimum temperature for germination of A. pilosa seeds was after 20 days stratification duration at , the germination rate than highest, 86% at that temperature. The stratification increased germination rate in all the temperatures treated, shortened days of germination period and promoted more 20% germination rate than the other treatments. Flowing water, low temperature, and NaOCl were not effective for germination and high temperature reduced germination rate. At the early growth stage, the plant height was taller , one or more leaves were increased by the stratification treatments, and also stratification increased the number of leaves per plants 10 or more leaves compare with other treatments at harvesting stages. By stratification, the flowering date was 5 days earlier, June 18th than other treatments due to earlier sprouting.
