杭白芍结实性状及籽油品质分析

分析杭白芍结实性状及其籽油品质,为芍药籽油专用品种培育及籽油开发利用提供理论参考。对杭白芍的结实性状相关性和籽油理化性质进行测试和分析,结果表明:(1)单心皮种子数和心皮长均与单株产量呈极显著正相关,蓇葖果数与单株产量呈显著正相关,分株数与单株产量呈显著负相关;主成分分析表明,前4个主成分累计贡献率达88.8768%。(2)籽油测试结果表明,种子含油率21.31%,油酸40.56%,亚油酸29.16%,亚麻酸22.11%,籽油不饱和脂肪酸91.83%,维生素E含量79.64 mg/100 g。因此,在选育高产品系时要重点关注单心皮种子数、心皮长和蓇葖果数等性状指标。杭白芍籽油具有较高的食用价值,可以作为一种新型的油料作物,具备深入研究推广的价值。

Seed Setting Characteristics and Seed Oil Quality of Paeonia lactiflora

To provide reference for breeding and seed oil development of Paeonia lactiflora, the seed setting characteristics and seed oil quality of P. lactiflora were analyzed and evaluated, to reveal the correlation between seed setting characteristics and seed oil quality. The results showed that: (1) the length of the carpel and the number of seeds per carpel were highly and positively correlated with yield, the number of follicle was positively correlated with yield, whereas the number of ramet versus yield was significantly and negatively correlated; principal component analysis showed that the first four principal components could explain 88.8768% of the total variance; (2) the oil content of seed was 21.31%, the content of oleic acid, linoleic acid and linolenic acid was 40.56%, 29.16% and 22.11%, respectively, the content of unsaturated fatty acid was 91.83%, the content of vitamin E was 79.64 mg/100 g. Therefore, it is important to pay attention to the number of carpel, the carpel length and the number of follicle in breeding high-yield strain. These results suggest that seed oil of P. lactiflora has better edible oil properties and a good promotion potential as new edible oil.
