Abstract:
Aralia elata (Miq.) Seem.branches were taken as tested materials for conducting off-seasion cultivation in winter.Four length(20 cm，30 cm，40 cm and 50 cm) and four width (1.1 cm，1.4 cm，1.7 cm and 2.0 cm) of branches were set up,and the effect of different branches length and width on the yield and qualities of bud were studied.The results showed that branch trait had a signifincant effect on yield and trait of Aralia elata (Miq.) Seem.buds,and with branch lengh and width increasing,germination rate and yield per plant were generally increased.Relative growth rate of buds displayed slow-fast-slow growth rhythm showing S-shaped basically.The contents of soluble sugar,soluble protein,saponins and flavonoids of buds increased with branch lengh and width increasing and the max bud germination of length 50 cm and width 2.0 cm reached 100% and the yeild of terminal bud and single plantbud reached 23.40 g and 113.50 g showing significantly higher than other treatment,the contents of soluble sugar,soluble protein,polysaccharides,saponin and flavonoids of terminal buds were 1.8 mg?g-1,5.95 mg?g-1,6.76%,6.67%,and 9.60%,respectively showing significantly higher than other treatment.In summary,the branches of length 50 cm and width 2.0 cm could obtain higher returns on off-season production of Aralia elata (Miq.) Seem..
