摘要
普通花生含油量高,在自然温度下易快速劣变丧失种子活力。这是我国北方仅上年或上一季花生而我国南方仅秋花生来年可做种的原因。本研究首次证实,高油酸花生经过19个月自然条件下贮藏,在多数种用特性上不差于上年收获的花生。所有参试的3个高油酸品种,其2013年种子与2014年种子在第7天的发芽率和田间出苗率均无显著差异。由此证明,高油酸品种不仅有利于健康,能延长制品货架期,而且可保持种子活力。
As high in oil,common peanuts may quickly deteriorate and lose seed vigor under ambient conditions.That is the reason why only seeds harvested in previous season/year can be used as seeds in north China,and only the fall crops producd seeds can be chosen for next spring＇s crop in south regions of China.The present study revealed,for the first time,that high-oleic（HO）peanuts after an extended period of storage at ambient temperature（19months）,were still as good as those harvested from previous year in most of the seed quality characteristics.For each of the 3HO peanut cultivars used,seeds of 2013 and 2014did not differ significantly in standard seed germination on the7 th day and field emergence.Use of HO peanuts may therefore sustain the vigor of seed,in addition to health benefits for humans and longer shelf life of food products.
