不同花生品种白藜芦醇含量鉴定评价

Identification and evaluation of resveratrol content in different peanut varieties

本研究选取59份花生品种,连续2年在武汉、石家庄、濮阳和周口4个地点共8个环境种植,成熟收获后检测花生籽仁白藜芦醇含量。结果表明,供试花生品种白藜芦醇含量在品种间、环境间均存在极显著差异。武汉环境下所有材料两年白藜芦醇含量均值相对较高。综合分析2年4点种植的检测结果,筛选出多个环境下白藜芦醇含量表现较高且稳定的材料2份(冀花2号和冀花13号)。结合前期对这些品种的含油量和脂肪酸检测结果的相关性分析表明,花生籽仁白藜芦醇含量与含油量和8种主要脂肪酸含量均不存在显著相关性。本结果为培育高白藜芦醇兼具高油和优良脂肪酸组成的花生品种提供了理论基础。

Fifty-nine peanut varieties were selected and planted in Wuhan,Shijiazhuang,Puyang and Zhoukou in 2016-2017.The content of resveratrol in peanut seeds was detected by high performance liquid chromatography(HPLC)after harvest.The results showed that the content of resveratrol in peanut varieties was significantly different between varieties and environment.The average content of resveratrol in Wuhan was relatively higher than that of other sites.Based on the comprehensive analysis of the detection results of planting in 4 areas in 2 years,two materials with high and stable resveratrol content under multiple environments were selected(Jihua 2 and Jihua 13).The correlation analysis of oil content and fatty acid test results of these varieties showed that there was no significant correlation between resveratrol content of peanut seed and oil content or 8 main fatty acids.The results provided a theoretical basis for cultivating peanut varieties with high resveratrol,high oil and excellent fatty acid composition.
