The kinetics of net ammonium influx were very similar among several cultivars of barley (Hordeum vulgare) and several accessions of the wild taxa H.v. spontaneum and H. jubatum. For net nitrate influx, variation was greater among accessions than among species; accessions from warmer climates had faster rates than those from colder climates. These data indicate that domestication of barley has not reduced its affinity for mineral nitrogen.
几种大麦（Hordeum vulgare）品种以及野生分类群野生大麦（H.v. spontaneum）和球茎大麦（H. jubatum）的几个种质中，铵净流入动力学非常相似。对于硝酸盐净流入，种质间的差异大于物种间的差异；来自温暖气候的种质比来自寒冷气候的种质具有更快的流入速率。这些数据表明，大麦的驯化并未降低其对矿质氮的亲和力。
