甘肃沿黄灌区引进枣品种的品质性状评价

为明确甘肃沿黄灌区引进枣品种的品质性状，以35个枣品种定植后4年生枣果为试验材料，测定其单果鲜重、核重、可食率、果皮色差、枣果脆度、含水量、口感、含糖量、含酸量、糖酸比、Vc含量等11个果实品质性状指标。采用因子分析法对其进行数据处理分析、综合评价和综合排序。结果表明，提取的前6个主因子的累计贡献率达到92.00%，可以作为评价引进枣品种果实品质性状的综合指标。综合得分从高到低依次是:甘酥佛枣、早脆王、骏枣、晋矮3号、蜂蜜罐、小梨枣、冷白玉、马牙白枣、七月鲜、晋矮4号、壶瓶枣、板枣、金谷大枣、赞皇大枣、不落酥、冬枣、金昌1号、马铃枣、星星枣、晋赞大枣、新郑早红枣、尜尜枣、六月鲜、新郑灰枣、孔府酥脆枣、灰枣、阜新大枣、胎里红、悠悠枣、曙光、北京鸡蛋枣、新星无核、磨盘枣、葫芦枣、龙枣。

Fruit Quality Evaluation of the Introduced Jujube Varieties in Yellow River Irrigated Regions of Gansu

In order to clarify the quality characters of the introduced Ziziphus jujuba varieties in Yellow River irrigated regions of Gansu,eleven indexes related to fruit quality were determined by using the fruits of 35 Z.jujuba cultivars that grew 4 years after planting as test materials.The indices included teh single fruit fresh weight,kernel weight,edible rate,skin color difference,fruit fragility,water content,taste,sugar content,acid content,sugar-acid ratio,Vc content.The data processing analysis,comprehensive evaluation and ranking were carried out by factor analysis.The results showed that the cumulative contribution rate of the first 6 extracted factors reached 92.00%,which could be used as comprehensive indices to evaluate the fruit quality and characters of Z.jujuba varieties.Comprehensive scores of 35 varieties were given.
