5种枸杞的果实性状及主要营养成分

Study on the characters and major constituents in the fruits of five wolfberry varieties

调查测定5种枸杞种质资源的农艺性状和质量性状,比较分析了4种黄果枸杞(W-11-15、W-12-27、W-12-30、‘宁夏黄果’)与红果枸杞‘宁杞1号’的表型特征特性及营养成分的差异。结果表明,W-11-15、W-12-27、W-12-30三种黄果枸杞具有不散粉的特性;黄果枸杞的果实大小、单株产量均小于红果枸杞‘宁杞1号’,但鲜果出汁率明显高于‘宁杞1号’(80%左右);相对于‘宁杞1号’,黄果枸杞的总糖、枸杞多糖和类胡萝卜素含量较低,但具有高黄酮的特性;黄果枸杞的果糖含量较‘宁杞1号’低,但葡萄糖含量较高,尤其是W-12-30果实中的葡萄糖含量比‘宁杞1号’高34.47%。

The characters and nutrients of five wolfberry germplasms W-11-15,W-12-27,W-12-30,‘Ningxiahuangguo＇and‘Ningqi No.1＇were comparatively analyzed. The results indicated that there was no pollen spilling out from the androeciums of three wolfberry germplasms W- 11- 15,W- 12- 27 and W- 12- 30. The average fruit weight and per plant yield of yellow-fruit wolfberry were lower than red-fruit wolfberry ‘Ningqi No.1＇,but the juice yield of yellow-fruit wolfberry was 80%,all higher than red-fruit wolfberry ‘Ningqi No. 1＇ evidently. There were lower total sugar,lycium barbarum polysaccharides and carotenoid but higher flavone in the fruits of yellow-fruit wolfberry than ‘Ningqi No.1＇. The content of fructose in the fruits of yellow-fruit wolfberry was lower than ‘Ningqi No.1＇,but the content of glucose was higher synchronously. The content of glucose in the fruit of W-12-30 was 34.47% higher than ‘Ningqi No.1＇. The germplasms W- 12- 27 and W- 12- 30 had larger fruits and higher yield than other germplasms. They could be taken as special varieties for wolfberry beverage processing.
