摘　　要：在黑龙江绥棱和内蒙磴口试验区对俄罗斯11个大果沙棘品种和蒙古1个大果沙棘品种的果实特性进行了比 较研究,结果表明:(1)黑龙江绥棱试验点百果质量在38．33-67．59 g之间,磴口试验点为32．87-63．85 g。在供 试的品种中除卡图尼在2个试验点百果质量一致外,其余品种百果质量在磴口试验点均比绥棱试验点有不同程度 的下降。引进品种除阿尔泰新闻外,其余品种的百果质量均显著低于原产地俄罗斯,反映出百果质量随纬度下降而 下降的趋势。(2)不同品种果实横径与纵径呈紧密线性相关,即随着果实纵径的增大横径随之增大。(3)果实纵 径、横径、长宽比三个指标与百果质量均达到极显著线性相关,因此可根据果实形状指标对百果质量进行预测。 (4)供试的11个大果沙棘品种果汁Vc含量在342．6-1770．3 mg·kg-1之间,与俄罗斯原产地Vc含量(470- 3300mg·kg-1)相比均有不同程度的下降。(5)供试大果沙棘品种浆果果汁中VE含量在4-29 mg·kg-1之间。 总黄酮在36-429 mg·kg-1之间,其中槲皮素、山奈酚和异鼠李素分别为21．9-310．8 mg·kg-1、1．0-9．8 mg· kg-1和13．1-133．8 mg·kg-1,很明显总黄酮主要由槲皮素和异鼠李素组成,而且二者的含量比较接近。Berry characteristics of 11 Russian Cuhivars and 1 Mongolian Cuhivar of seabuckthorn （Hippophae rhamnoides） were studied at 2 sites, Shuiling of Heilongjiang and Denkou of Inner Mongolia. The 100-berry-weight was 38.33 - 67.59 g and 32. 87 - 63.85 g of the cultivars in Suiling and Dengkou respectively. Except for 1 cuhivar, the 100-berry-weight of the other 11 cuhivars in Dengkou was lower than that in Suiling, indicating that the berry weight of seabuckthorn was correlated with the latitudes of the cultivar origins. Significant linear correlation was found between width and length of berry. The berry length ,the width and the length/width ratio were all significantly correlated with the 100-berry-weight, therefore , these 3 traits describing berry shape can be used to predict 100-berry-weight. The content of vitamin C in berry juice of the tested large berry cuhivars varied from 342. 6 mg ·kg^-1 to 1 770. 3 mg · kg ^-1, which evidently lower than that of the original Russian cuhivars varying from 470 mg · kg^-1 to 3 300 mg · kg^-1. The content of vitamin E and total flavones in berry juice of the 12 tested large berry cultivars were 4 - 29 mg · kg^-1 and 36 - 429 mg · kg^-1 respectively.
