摘要

Species of the genus Panax L. known as ginsengs are perennial forest herbs. The medical values of ginsengs are well known. Panax vietnamensis var. fuscidiscus was found in Laichau province, North Vietnam in 2003 and is known as Laichau ginseng. Understanding the ecology and saponin of high economically valuable Laichau ginseng is becoming important for sustainable development and management. Plots of 400 mSUP2/SUP (20 m × 20 m) were established to survey for Laichau ginseng’s ecological characteristics. In addition, its root samples from natural forests and garden of local people were collected for saponin analysis and anatomy. The results indicated that Laichau ginseng naturally distributes in evergreen broadleaved forests in elevation zones up to 2,100 m above sea level. It can grow in both old-growth forests and anthropogenic-disturbed forests. However, the total crown area of tree (stem with a diameter at breast height ≥5 cm) layer must be high, ranging from 3.2 to 8.6 times of the land area. In addition, the cover of herb layer is also important, which must be ≥44% land area. The saponin content of Laichau ginseng in natural forest (23.85%) is statistically significantly higher than that of other ginsengs (3÷22.29%) naturally distributing in Vietnam. While saponin content of Laichau ginseng (18.48%) grown in the garden of local people is statistically significantly lower than that collected from natural forests. It is concluded that Laichau ginseng could be a potentially perennial forest herb for poverty reduction. However, growing this herb may be restricted to very narrow areas in high elevational evergreen broadleaved forests with a high cover rate of both tree and herb layers.
