The flower organ was anti-ancestral, the pedicel lengthened 3-6 times as much as the normal flower, and the sepals, petals, stamens and pistil grew abnormally, forming light green leaflets. For the diseased trees with strong potential, there will be dwarf twigs in the axils of leaflet leaves, forming clumps of branches. 2. Developing branches, positive and accessory buds and fruiting mother branches germinate and grow many times a year, continuously producing small yellow-green branches and leaves, forming dense branches and clumps, which are not easy to fall off in winter. 3.
