| 摘 要： | 以一年生辽东楤木枝条为试材，根据枝条木质化和纤维化程度将枝条分为1 级、2 级和3 级，利用日光温室进行反
季节栽培，研究枝条成熟度对辽东楤木嫩芽生长以及营养成分含量的影响。结果表明：枝条的成熟度显著影响辽东楤木嫩芽
的生长及品质，随着枝条成熟度的增加，嫩芽的萌发率明显增大，嫩芽单株产量、可溶性糖、可溶性蛋白质、VC、多糖等
营养成分含量以及次生代谢产物皂苷和黄酮的含量也显著上升。综上所述，辽东楤木反季节生产中应选择成熟度高、木质化
程度良好的枝条，能够获得较高的经济价值。 |

| Abstract: | 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． |
