The result of comparative studies on the growth and fruiting habits, fruit characteristics, adaptability and resistance of the introduced atemoya cultivar Pierce(Annona hybrid ‘Pierce’)and local cultivar Sugar apple (A. squamosa L.)showed that the leaves of Pierce fall in January and February, the trees begin to sprout in the late March, to develop the flower buds in the early April. The trees can bloom many times during the sprouts growing seasons. The principal harvest time can be adjusted from autumn to winter by summer pruning. The trees began to bear in the 2nd year after planted, and the yield reached 15246kg/hm2in the 5th year. Piece has the characteristics of good fruit quality with the single fruit weight of 269g, a soluble solids content of25.3%, an edible rate of81%, a sugar content of 21.9%, an acid content of 0.3%, a vitamin C of 42.4mg/100g. The trees are high cold resistant at fruit development period in winter.
