兔眼蓝浆果在南京地区的生长和结实情况

从美国引入的１２个兔眼蓝浆果（ＶａｃｃｉｎｉｕｍａｓｈｅｉＲｅａｄｅ）品种在南京地区的生长和开花结果情况表明，大部分品种与原产地无明显差别。树冠略小于原产地。除个别品种外，单株产量一般高于或与原产地相近。说明兔眼蓝浆果对南京地区自然条件比较适应。但各品种适应程度有差异。适应性最强的品种有Ｂｒｉｇｈｔｗｅｌ、Ｂｌｕｅｂｅｌｅ、Ｃｌｉｍａｘ和Ｇａｒｄｅｎｂｌｕｅ，最差的是Ｄｅｌｉｔｅ，其他品种一般。花期早晚与倒春寒危害有关，值得注意。

Growth and fruiting of Rabbiteye blueberry in Nanjing Area

It was shown by the growth, flowering and fruiting of the 12 cultivars of rabbiteye blueberry in Nanjing introduced from the United States that no significant difference has been found with those in the original producing area. The crown size is a little smaller and, with very few exceptions, most of the cultivars have higher yield per plant or so than that in the United States. That means the rabbiteye blueberry is rather adaptable to the natural condition of Nanjing area. But the degree of adaptation are different. Among the 12 cultivars, Brightwell, Bluebelle, Climax and Gardenblue are the best and Delite is the worst. The risk of frost injury in spring is related to the blooming period of different cultivars.
