Abstract
The ecological adaptability and propagation of Pyrus calleryana 'Capital' were studied.The results showed that the annual growth and development law of germination, flowering, leaf spreading, growth, fruit setting and defoliation of Pyrus calleryana 'Capital' can be com-pleted in the experimental area, and the leaves turn dark red or red from mid-october to November, and the annual viewing period for colored leaves is 25 d.Pyrus calleryana 'Capital' can be propagated by grafting, and the survival rate of grafting can reach about 90.0％.Pyrus call-eryana 'Capital' has strong adaptability to the cold and dry climate in winter and hot and humid climate in summer in Beijing, and can grow normally on cinnamon soil, fluvo-aquic soil and loam soil, it is an excellent color tree species for autumn foliage viewing in Beijing.
