贮藏期对花生种质籽粒成分影响研究

Research of Storage Period on Seed Components of Peanut Germplasm

常温干燥贮藏是植物种质资源保存的重要方式之一。研究表明,在常温干燥条件下,经过11年的保存,花生不同类型籽粒成分发生程度不同的变化,其中总糖含量随贮藏时间而增加,蛋白质和粗脂肪含量整体呈降低趋势,脂肪酸中除油酸含量随贮藏时间延长而升高外,棕榈酸与亚油酸含量均降低。VE除多粒型与中间型外,其余类型花生种质均随贮藏时间延长而降低。同时,花生种质的外观品质性状不随贮藏时间延长而发生显著变化。

Dry and common temperature storage is one of the main storage methods of plants germplasm. The purpose of this trial was to observe the changes of seed components after 12 years storage. Results showed that, in 8% moisture content and common temperature storage condition, various changes turned out in seed components of different kinds with elongation of storage period. Total sugar content increased with storage period prolonged, but protein and oil content decrease. As to fatty acid, palm acid and linoleic acid content decreased with storage period prolonged except oleic acid content. VE content of all kinds of the peanut germplasm decreased with storage period prolonged except for var. fastigiata and irregular type. In addition, the aspect characteristics of peanut germplasm didn＇t change distinctly with long term storage.
