新疆6种驯化蔷薇果实的主要经济性状及果实营养成分含量分析

Economic Characters and Nutrient Components in the Fruits of Wild Rosa from Xinjiang

以新疆野生蔷薇种质资源圃6—11年生引种驯化的6种蔷薇为材料，测定其在引种条件下，蔷薇果实的主要经济性状及果实营养成分含量，比较不同蔷薇种间的产量高低与品质优劣。结果表明，单枝条结果量最多的是弯刺蔷薇（135．4颗），最少的是尖刺蔷薇（27．3颗）；平均单果重最大的是大花密刺蔷薇，为1．477±0．112g，最小的是弯刺蔷薇，为0．438±0．051g；单枝果产量最多的是大果蔷薇，为2447．388±5．741g，最少的是刺蔷薇，为648．046±2．181g；总酸、总糖、维生素c、氨基酸类、粗蛋白质、微量元素钙和锌的含量均为疏花蔷薇最多，总黄酮含量刺蔷薇最多。最后对引种的6种新疆野生蔷薇的生物学特性和资源开发利用价值进行了评价。

To compare interspecific difference of productivity and quality, the major economic characters and fruit nutrient component of some introduced Rosa species were measured by selecting 6 introduced Rosa species with 6- 11 years old. The result shows that Rosa beggeriana Schrenk has the maximum quantity of fruit of single branch （135.4） while Rosa oxyacantha M. Bieb. has the minimum quantity （27.3） . Rosa spinosissima L. var. altaica has the heaviest average single fruit weight 1. 477±0.112g while Rosa beggeriana Schrenk has the lightest 0. 438 ± 0. 051 g. Rosa albertii Reg. has the maximum quantity of fruit of single stem 2 447. 388±5. 741g while Rosa acicularis Lindl. has the minimum quantity 648. 046±2. 181 g. In terms of the content of total acid, total carbohydrate, vitamin C, amino acids, crude protein, trace elements Ca and Zn, Rosa laxa Retz. ranks in first place, and Rosa acicularis Lindl. has the most abundant total flavonoids. The biological characteristics and potential utilization value of these 6 introduced Rosa were also evaluated.
