Abstract
The researchers studied the composition of latent buds by surveying the embryo of harvested seed, and the developmental pathway of latent buds by analyzing the characteristics of local ginseng. One-year-old ginseng seedlings were transplanted into the field and harvested two years later. The developmental pathway of the main bud, which would be the shoot of ginseng in the fourth year, was also investigated. The main bud of the seedling was formed from the region between root and shoot of the germinating seed. Primary and axillary latent buds protruded in a dome-shape from the cortex and separated from the main bud. Ninety percent of the single main bud was derived from the primary latent bud. Twin main buds were derived from a primary latent bud and one axillary bud, and triple main buds were derived from primary latent bud and two axillary latent buds. In the field, the researchers could not find 2-stem plants in 2-3 years old plants. However, the researchers found a 2-stem plant in a 4-year-old plant because its two main buds developed from a 3-year-old plant. We can conclude that a 2-stem plant was observed in the plant that was at least 4 years old. The main buds of the 4-year-old plant were formed at the primary and axillary latent bud of seed and cortex, the latent bud of rhizome in a 2-3 year old plant. In older plants, twin and triple main buds were derived mostly from the cortex latent bud than the primary latent bud.
