摘要
１９８８年由美国引入１２个兔眼蓝浆果（ＶａｃｉｎｉｕｍａｓｈｅｉＲｅａｄｅ）品种，在江苏南京和溧水两地试种。１０年来生长结果正常，产量和品质与原产地无显著差异，引种获得成功，证明兔眼蓝浆果能适应本地区自然条件。单株产量平均７．５１ｋｇ，品种间差异显著，最高９．８６ｋｇ，最低１３４ｋｇ。单位投影面积产量３．１０ｋｇ／ｍ２，最高４．０６ｋｇ／ｍ２，最低１．１３ｋｇ／ｍ２。高于或至少不低于原产区产量记录。据此预测，栽植距离适宜时，在本地区亩产量可达１５００～２０００ｋｇ以上。大多数品种果实糖酸比很高，鲜食风味好，氨基酸含量中等，矿质元素Ｚｎ和Ｓｅ含量高。兔眼蓝浆果可在江苏南部丘陵地区发展；此外，还应将试验扩大到南方红黄壤地区；并对本国野生资源开展研究和利用。
Twelve cultivars of rabbiteye blueberry were introduced into Nanjing and Lishui, Jiangsu Province from the United States in 1988. After 10 years plantation, it is obvious that most of the cultivars were successfully adapted to the natural condition of this area. The mean yield per plant is 7.51 kg, differences among cultivars are quite evident as from 9.86 kg the highest to 1.34 kg the lowest, mostly higher than that in the original producing area or so. For yields per unit projective area of crown, it is 3.10 kg/m 2 in average, 4.06 kg/m 2 the highest and 1.13 kg/m 2 the lowest. So it is estimated that in this area, under the appropriate planting distance,\ a yield of 1 500～2 000 kg per mu (1/15 hm 2 ) is possible. Concerning to the fruit quality, most of the cultivars have higher sugar acid ratio and fine taste, the amino acids content is moderate whereas that of minerals Zn and Se are high. It is suggested by the authors that the rabbiteye blueberry could be developed in the southern hilly area of Jiangsu Province; the introduction experiment of American blueberries might be extended to the red yellow soil region; attentions should also be paid to the domestic wild resources of the genus.
