What are the growth and development characteristics of Panax notoginseng?

Medicinal Herb Cultivation 0 views
Panax notoginseng seeds have after-ripening characteristics and must be stored under moist conditions to complete physiological after-ripening and germinate. Once the seeds dry out, they lose their viability. A one-year-old seedling grows only 1 palmately compound leaf; in winter the stems and leaves wither, and around the spring equinox of the second year, new shoots emerge from the rhizome above ground. In winter it is dormant, and in spring of the second year it sprouts and grows stems and leaves. If the young bud is damaged that year, it cannot germinate into a seedling the following year and must remain dormant underground for one year; after a new bud forms the following year, a new shoot grows in the spring of the third year. One-year-old plants do not bolt

One-year-old plants do not bolt or flower, most two-year-old plants bolt and flower but bear few fruits, and three-year-old plants generally flower and bear fruit.
