Germination, Laichau ginseng,, phenologyAbstract
Laichau ginseng (Panax vietnamensis var. fuscidiscus Komatsu, Shu & Cai) is highly regarded medicines in Vietnam for various diseases and tonic drugs for the elderly. This species is considered to be endangered and its distribution is limited. Therefore it need urgent to phonological growth stages investigate, which is important to establish technique propagation and cultivation. Four principal growth stages for germination, bud development,
root formation and inflorescence, flowering, fruiting, ripening were obtained. Flowering was observed in the end of March to the end of May; Maturity fruit in the beginning of May to the end of September; Rip fruits from July to
September. The highest germination rate was observed at 70% within 75-90 days when seeds were treated by soaking with concentrated GA3 700 ppm for 24h. Catalogue the data of Phenology growth stages of Laichau ginseng are essential when developing management’s strategies for use in the conservation and sustainable utilization of the researched medicinal plants within Vietnam.
