甘薯

It was a rule of the Peterkin family, that no one should eat any of the vegetables without some of the meat; so now, although the children saw upon their plates apple-sauce and squash and tomato and sweet potato and sour potato, not one of them could eat a mouthful, because not one was satisfied with the meat.

彼得金一家有一条规矩，在吃完肉之前，谁也不许吃一点儿蔬菜；所以，虽然孩子们坐在那些装着苹果沙司、南瓜、西红柿、甘薯、腌土豆①的盘子旁边，却没人能尝上一口，因为谁不爱吃自己分到的那份肉。

Stems of Ipomoea batatasLam in vitro were cultured on MS rhizogenic base medium. ifferent combinations of CO2 concentration and photosynthetic photo flux density in microenvironment were controlled and recorded by special system. The plantlets getting the highest net photosynthetic rate were treated by the combination of (Ci=8 720 μmol mol-1,PPFD=250 μ mol m-2 s-1). Then, the plantlets had been further cultured for 21 d in such microenvironment.

以新兴蔬菜叶用甘薯组织培养苗的茎节段作为外植体，用MS低糖、无激素培养基进行生根培养，设置不同的CO2浓度和光合光量子通量密度对组培植株进行环境调控处理，获得小植株净光合速率最高的处理组合=8 720 μmol mol-1， 250 μmol m-2 s-1），并在此组合下继续培养21 d。

甘薯NBS类抗病基因类似物的分离与序列分析。

As an example, sweet potato is characterized with fleshy tuberous roots for nutrient storage. Factors directing the induction of early tuberization have been investigated for a long time in sweet potato.

块根膨大过程中的营养元素需求、形态变化、内在植物激素消长等方面，长久以来已被广泛研究，但是其基因调控机理至今仍不明确；为此，本研究欲著眼於分子层面来探究甘薯的块根形成机制。

Four thin-layer drying models were investigated for the description of FIR-assisted freeze-drying characteristics. The models were exponential model, Page model, diffusion model, and approximation of the diffusion model. Tests were conducted using a three-level, three-factor (drying temperature, distance between sample and FIR heater, and sample thickness) design, and quadratic polynomial analyses were performed to relate the drying parameters of thin-layer drying model. The performance of these thin-layer drying models was evaluated by comparing the coefficient of correlation (R2), the sum of squares, and the RMSE amongst four models. Drying parameter K of the Page model gave the best results in describing freeze-drying with FIR of Tylose and sweet potato.

运用四种薄层乾燥模型（指数、Page、渗透模型及近似渗透模型）研究远红外线冷冻乾燥之乾燥特性，实验采用三阶层、三因子（远红外线加热器设定温度、远红外线加热器至样品表面之距离及样品之厚度）的实验设计，对於薄层乾燥模型的乾燥参数以二次多项式函数表示之，乾燥参数之二次多项式函数的最适性判断主要是藉由决定系数、模式缺乏适合性及均方根误差等值的比较而加以评估，以Tylose及甘薯样品而言，其中四种薄层乾燥模型的乾燥参数以Page模型之K值的结果为最佳。

Six pairs of primers with polymorphism among 36 accessions were used to amplify the genomic DNA.

利用分子标记SRAP技术，对36个甘薯品种进行了DNA多态性分析。

These data prove that the enzyme is compartmented in its functional sites, and so provide evidence to support the possible widespread biological function of the enzyme in catalyzing starch breakdown in plant living cells or at least in living cells of plant storage organs.

这些结果明确地展示出甘薯块根生活细胞中β-淀粉酶与其淀粉基质居于同一亚细胞区域内，为β-淀粉酶普遍参与植物生活细胞或贮藏器官生活细胞中的淀粉水解提供了证据。

Cv. Xushu 18 and via immunogold electron-microscopy technique, showed that β-amylase visualized by gold particles was predominantly localized in plastids especially at periphery of starch granules, but the gold particles were scarcely found in other subcellular compartments, indicating that the enzyme is subcellularly compartmented in the same zone as its starch substrates.

本研究利用胶体金免疫电镜定位技术证明，甘薯块根生活细胞中的β-淀粉酶也是主要定位于质体内，围绕淀粉粒分布较多，其他亚细胞区域内β-淀粉酶分布很少，说明该酶主要分布于其功能区域。

In China and many other Asian countries, sweet potatoleaf stalks may be found in restaurants, eateries and meals of populace as a special vegetable.

在中国和其他的许多亚洲国家，甘薯叶柄作为一种蔬菜可以在餐馆、食堂和一些平民的餐桌上看到。

Originally, all felts were woven from spun yams and were mechanically felted or "fulled" to proved bulk and stability.

起初，所有被编织毛毯从纺甘薯和被机械粘结或& fulled &，以证明松厚度与稳定性。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
