Seeds of Trigonella foenum-graecum are examined light microscopically and by chemical analysis at different stages of germination.In the earliest stages of germination the raffinose family oligosaccharides are metabolised both in the endosperm and in the cotyledons of the seed but there is no change in the appearance, amount or composition of the main carbohydrate reserve, a galactomannan localised in the endosperm. About 18 hours after the emergence of the radicle the endosperm galactomannan begins to be mobilised. In a period of 24 hours the polysaccharide is completely degraded and the breakdown products, mainly galactose and mannose, are absorbed by the cotyledons in which sucrose increases and starch is formed.Mobilisation of the galactomannan is accompanied by the formation in the endosperm of a dissolution zone the form of which implies that the aleurone layer is involved in the degradation process.
鹰嘴豆种子在萌发的不同阶段进行了光学显微镜和化学分析检查。在萌发的最早阶段，棉子糖家族低聚糖在胚乳和种子的子叶中都被代谢，但主要碳水化合物储备（一种定位于胚乳的半乳甘露聚糖）的外观、数量或组成没有变化。在胚根出现后约 18 小时，胚乳半乳甘露聚糖开始被动员。在 24 小时的时间内，多糖完全降解，分解产物主要是半乳糖和甘露糖，被子叶吸收，其中蔗糖增加，淀粉形成。半乳甘露聚糖的动员伴随着胚乳中溶解区的形成，其形式表明糊粉层参与了降解过程。
