双子叶的

22 Of 22 pairs EST-SSR primers from Chinese cabbage/rape respectively had amplification products in soybean,wheat and maize,the rate of amplification was 81.8%,95.4%,100%,respectively;10 of 22 pairs EST-SSR primers showed polymorphism in monocotyledons wheat and maize,13 in dicotyledons oilseed rape and soybean,7 in both monocotyledonous and dicotyledonous crops.

（1）30对小麦EST-SSR引物中，有29，28和26对引物分别在玉米、油菜和大豆中有扩增产物，可扩增率分别为96.7%，93.3%和86.7%；其中分别有12对和9对引物在单子叶作物小麦和玉米及双子叶作物大豆和油菜中的扩增产物显示多态性，有4对引物在4种作物中的扩增产物均显示多态性。

These individual characters are similar to those of most aquatic plants in monocotyledonous Helodiales and dicotyledonous Nymphaeales, which reflects the phylogenetic relationships of Iris from aquatic plants to xerophil.

这些个体性状与单子叶沼生目和双子叶睡莲目多数水生植物相似，从一定程度上可以反映鸢尾属植物从水生到旱生的系统发生上的关系。

Seeds biseriate, broadly winged, orbicular, ovate, or elliptic; seed coat smooth, not mucilaginous when wetted; cotyledons accumbent.

双列的种子，具宽翅，圆形，卵形，或椭圆形；平滑，不黏的种皮被弄湿；子叶依着。

Seeds uniseriate or biseriate, broadly winged, proximally margined, or wingless, oblong or orbicular, flattened; seed coat smooth, not mucilaginous when wetted; cotyledons accumbent.

双列的种子单列或，具宽翅，下部边缘，或无翅，长圆形或圆形，扁平；平滑，不黏的种皮被弄湿；子叶依着。

Seeds uniseriate or biseriate, wingless, broadly ovate or suborbicular, flattened; seed coat reticulate, rugose, or papillate, not mucilaginous when wetted; cotyledons accumbent.

双列的种子单列或，无翅，宽卵形或近圆形，扁平；网状的种皮，具皱纹，不，或具乳突黏被弄湿；子叶依着。

With field pot experiment, the effects of two dosages of enhanced UV-B radiation on the morphology, physiology, biomass allocation, and chemical composition of C4 plant Amaranthus retroflexus were studied.

通过大田盆栽实验，研究了2种增强的UV-B辐射对双子叶C4植物反枝苋形态、生理、生物量分配及化学成分的影响。

The preliminary bioassay indicated that some of the target compounds displayed good herbicidal ac-tivity against Brassica campestris L at the dosage of 100 mg/L.

初步生物活性测试结果表明：该系列部分化合物在100 mg/L的浓度下对双子叶植物油菜显示出较好的除草活性。

Compared with the dicot, the monocots preferred GC-rich tri- and hexa- motifs very much, especially in rice where 23.6 CCG motif occurred in 100kb ESTs.

与双子叶植物大豆相比，单子叶植物似乎更偏好富含GC的三碱基和六碱基重复单元，特别是水稻中平均每100kb EST就有23.6个CCG类型的SSR出现。

Studies on several floral homeotic mutants in dicots, mainly in Arabidopsis, Snapdragan and Petunia, established the ABCDE model for the determination of floral organ identities.

根据对双子叶模式植物拟南芥、金鱼草和矮牵牛遗传突变体的研究，提出了花发育的ABCDE模型。

Salicornia europaea is a dicot halophyte,which could grow in marsh with salinities greater than 3.5%and the major osmotica in its fleshy stems was Na~+ and g lycine betaine.

盐角草是一种双子叶盐生植物，可在含盐3.5%以上的湿地正常生长，其体内主要的渗透调节物质是Na~+和甘氨酸甜菜碱。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
