新经济植物黑莓的引种

黑莓（Ｒｕｂｕｓｓｐｐ．）是第三代新兴的小果类果树之一。江苏省植物研究所于１９８６～１９８８年从美国引进了７个黑莓品种，从中选出适合江苏地区栽培的Ｈｕｌｌ，Ｃｈｅｓｔｅｒ，Ｂｌａｃｋｓａｔｉｎ３个品种，并已初步推广。田间试验对３个品种的发枝习性、开花结果习性和产量构成等进行比较。Ｈｕｌｌ单株产量最高，果实最大，ＢｌａｃｋＳａｔｉｎ单株产量最低，果实最小。但若种植密度适宜，３品种均能达到高产。

Blackberry introduction and cultivation

Seven cultivars of blackberry have been introduced from the United States since1986.From which 3 cvs.,Hull, Chester and Black Satin,were selected out and spreaded. In the field experiment,branching,flowering and fruiting behavior, yield composition etc. were compared among cultivars.The indi vidual yield of Hull was the largest as well as the aggregate fruit size,whereas that of Black satin were the lowest. Even though three cultivars were all high yielding if the planting density is appropriate.
