Taking annual Aralia elata(Miq.)Seem. as material,this study divided the branches into 1,
2 and 3 levels,according to their lignification and fibrosis degrees;and studied the effects of branch maturity
on growth and nutrient contents of young buds,by out-of-season cultivation in solar greenhouse.The results
showed that branch maturity could obviously affect the young bud growth and quality.The sprouting rate
and single plant bud yield increased significantly with the increase of branch maturity.Besides,the nutrient
contents of soluble sugar,soluble protein,VC and polysaccharide,etc. and secondary metabolites including
flavonoids and saponins all showed an increasing trend.In conclusion,selecting branches with high maturity
and favorable degree of lignification in out-of-season Aralia elata(Miq.)Seem. production could achieve
higher economic value.
