南瓜6种营养品质性状间的相关性研究

Investigation on Correlation between Six Quality Traits in Pumpkin

选用25个形态差异较大的南瓜品种,研究其β-胡萝卜素、干物质、蛋白质、粗纤维、总糖、Vc等6项营养品质性状之间的相关性,旨在探讨用简单易测的营养品质性状,对大量育种早代材料进行快速可靠品质筛选的可行性。结果表明,在南瓜的6种营养品质性状中,β-胡萝卜素和干物质、蛋白质、总糖、Vc,干物质和Vc、蛋白质,Vc和蛋白质之间的相关系数均达到显著或极显著水平;南瓜粗纤维和其他5种营养品质间的相关系数均未达到显著水平,并且和总糖、Vc之间呈负相关。

25 pumpkin cultivars were chosen to investigate the correlation between β - carotene, my matter, protein,cellulose, total sugar, Vc. The results indicated that the correlation coefficients of β- carotene and dry matter, protein, total sugar, Vc, dry matter and protein and Vc , protein and Vc were at the significam or very significant level. The Correlation coefficients of cellulose and other 5 quality traits were at the no significant level. The cellulose has negative correlations to sugar content and Vc.
