脱水敏感的黄皮种子发育至生理成熟时淀粉积累达最大值，但其胚轴中淀粉含量远低于子叶且在种子成熟以后明显下降。花后65d子叶中可溶性糖含量最高而胚轴中可溶性糖随种子发育而一直上升。还原性葡萄糖和麦芽糖含量随种子发育而逐渐降低．非还原性果糖和蔗糖则逐渐增加。生理成熟期子叶中还含有较多的水苏糖和棉籽糖。外源ABA可提高成熟林子子叶中蔗糖的含量和未成熟种子的淀粉含量、但不能提高种子的耐脱水能力。因此我们认为黄皮种子的碳水化合物变化与其所在组织（子叶和胚轴）的不同代谢模式有关，而不是与种子的脱水敏感性有关。
Dehydration-sensitive yellow seeds developed to the maximum value of starch accumulation at physiological maturity, but the starch content in the hypocotyls was much lower than that of cotyledons and decreased significantly after the seeds matured. The content of soluble sugar in the cotyledon was the highest at 65 days after anthesis, while the soluble sugar in the hypocotyl increased with seed development. Reducing glucose and maltose content decreased with seed development. Non-reducing fructose and sucrose gradually increased. Physiological cotyledons also contain more stachyose and raffinose. Exogenous ABA increased the sucrose content and the starch content of immature seeds in mature cotyledons, but did not improve the seed’s resistance to dehydration. Therefore, we believe that the carbohydrate changes in the seeds of the yellow peel are related to different metabolic patterns in the tissues (cotyledons and hypocotyls) of the yellow hulls rather than the dehydration sensitivity of the seeds.
