The characteristics of tree structure,organ morphology,phenological stage,vegetative and reproductive growth and ecological factors of growth and development were investigated.Result shows that the capacity of ger-minated rhizomes Aronia arbutifolia is very strong.The germination rate of rhizome planted for six years are 59.6%.New shoots grow faster in June.The ten-day average growth rate of new shoots is 6.9 cm. Stem-diameter is 0.05 cm;the branch of one-year-old tree is fruit branches. The number of six-year-old fruit-bearing branches is 83.8%. Fruit setting ratio is higher,generally up to 80%-90%.Aroniaarbutifolia can grow normally under condi-tion(below extreme low temperature of-30 ℃,annual rainfall being above 600 mm,the soil pH being 5.0-7.0, frostless period being above 160 d).
