In some seeds ( e . g . the endosperm of dates ) hemicelluloses are a food reserve 在一些种子中（如海枣的胚乳） ，半纤维素还是一种食物储备。
The nutritive tissue that is derived from the nucleus and surrounds the embryo of the seed 外胚乳包在种子胚芽外，产生于细胞核的营养性组织
In flowering plants , for instance , the early stages of endosperm development are often acellular 例如在开花植物中，早期胚乳的发育通常是非细胞组成的。
The guar seeds are dehusked , milled and screened to obtain the ground endosperm i . e . guar gum 瓜尔豆经脱壳、研磨以及筛分后就获得了基本胚乳，即瓜尔胶。
Many endospermic seeds ( e . g . cereals and oil seeds ) are cultivated for their food reserves 许多有胚乳种子（如谷类和油料种子）是由于其营养物质而专门栽植的。
Aleurone layer the outermost proteinrich layer of the endosperm of grass fruits ( e . g . cereal grains ) 糊粉层：在谷类种子胚乳最外面的一层或几层细胞，含有大量的糊粉粒。
In nonendospermic seeds most of the endosperm is absorbed by the developing embryo and the food stored in the cotyledons 在无胚乳种子胚的发育过程中，大部分胚乳被吸收，养料储存在子叶中。
5 . developing is an algorithm that distinguishes the face of endosperm by the image feature of endosperm 5 、研究并提出了判别玉米种子胚乳部所在面的检测算法，该算法利用胚乳部所在面的图像特征。
In endospermic seeds the endosperm replaces the nucellus and is often a rich source of growth - regulating substances 在有胚乳种子中，胚乳取代珠心，成为生长调节物质（应为营养物质译者注）的丰富来源。
So , the rank of inducing callus from easy to hard is cotyledon , hypocotyls , stem , leafstalk , radicel , endosperm , leaf and root . 3 诱导的难易分别为：根段、叶片、胚乳、胚根、叶柄、茎段、胚轴、子叶。
