利用近红外分析技术测定胡麻种质资源品质

利用Perten公司DA7200型近红外透射光谱分析仪,对甘肃胡麻种质资源库的364份胡麻资源的籽粒品质成分进行测定。结果表明,胡麻籽粒4种品质成分在不同材料间存在明显差异,硬脂酸、木酚素、棕榈酸和油酸变异系数较大;碘价、粗脂肪、亚油酸和亚麻酸含量的变异系数较小。资源中粗脂肪平均含量为38.64%,硬脂酸平均含量为4.94%,棕榈酸平均含量为5.58%,油酸、亚油酸、亚麻酸、碘价和木酚素平均含量依次为29.15%、11.4%、51.31%、175.69和9.60 mg/g。筛选出了123份优异种质资源供育种利用。并对近红外技术在胡麻品质育种中的利用作了探讨。

Application of the Near Infrared Reflectance Spectroscopy(NIRS) in Analyzing Flaxseed Germplasm Quality

The qualities of germplasm in Gansu Privince 364 flaxseed were analyzed in this paper by using near infrared reflectance spectroscopy(NIRS) analyzer,which was made by perten company.The content of crude-fat,palmitic acid,stearic acid,petroselinic acid,linolenic acid,linolenic acid,Iodine.value and lignan were determined.The result showed that the coefficient of variation was larger for stearic acid,lignan,palmitic acid and petroselinic acid,but the iodine.value,crude-fat,linoleic acid and linolenic acid content had smaller coefficient of variation.The average content was crude-fat 38.64%,palmitic acid 5.58%,stearic acid 4.94%,petroselinic acid 29.15%,linoleic acid 11.40%,linolenic acid 51.31%,iodine.value 175.69 and lignan 9.60 mg/g respectively.123 especial gemplasm were selected for flax breeding.The application of NIRS in flax quality breeding was discussed in the paper.
