查询词典 seed coat

Respiration was the most important limiting factor of fresh seed dormancy. Seeds without seed coat and aleurone layer germinated, but could not grow to normal seedling until finishing some metabolism. Drying could break fresh seed dormancy, but the effect of treatment with GA3 and H2O2 was not very significant.

呼吸是限制玉米鲜种子萌发的主要因素，去除种皮可以促使鲜种子萌发，但若要成长为正常幼苗还需体内代谢完成与幼苗生长有关的物质的合成，干燥可以使种子解除休眠，赤霉素、过氧化氢处理可一定程度解除鲜种子休眠，低温处理对解除玉米鲜种子休眠不起作用。

Seed usually 1; seed coat membranous; caruncle absent; endosperm absent.

通常的种子1；种皮膜质；种阜无；无胚乳。

Seed without caruncle; seed coat woody.

种子无种阜。种皮木质。

It could preferably defend seedlings against damping-off and Rhizoctonia rot in seedling stage, wilt disease and anthracnose in mature phase and increase field. After application in cowpea, Fenle Nutritious Seed Coating for beans and ZSB bean seed-coat agent (1:40 for ratio of the chemical to seeds) were selected, which increased emergence rate and improved seedling growth.

在豇豆种子上包衣应用后，筛选出效果较好的丰乐营养豆类包衣剂（药种比为1：40）和ZSB菜豆包衣剂（药种比为1：40），提高了豇豆种子的出苗率，促进了幼苗的生长，同时种衣剂对豇豆种子本身所带的炭疽病病菌和土传的猝倒病、枯萎病均有显著的防效，从而一定程度上提高了豇豆的产量。

The seed has a seed coat,an embryo and seed leaves.

种子由种皮胚和种叶组成。

In this paper, we review recent advances on mucilaginous seeds, with emphasis on （1） chemical composition of seed mucilage;（2） morphological characteristics of mucilaginous seed coats and mucilage;（3） biochemical processes in and genetic regulation of differentiation of mucilage-secreting cells, mucilage biosynthesis and mucilage secretion in the seed coat; and （4） ecological significance of seed mucilage.

为此，在广泛查阅相关文献的基础上，该文综合分析了国内外种子粘液的研究进展，并重点探讨了以下几方面问题：（1）种子粘液的化学成分：（2）粘液及粘液种皮的形态特征：（3）粘液细胞分化与粘液生物合成的细胞学及基因调控机制以及粘液的释放方式：（4）种子粘液的生态学意义。

Evidence from seed-coat micromorphological features supports placement of Ripogonum outside Smilacaceae and inclusion of Heterosmilax in Smilax, which are also consistent with palynological and molecular evidence. Within Smilax, seed-coat micromorphological features suggest close relationships between most of the species of sect.

种皮形态分析结果支持将Ripogonum属从菝葜科中分离、独立成科，支持将肖菝葜属与菝葜属合并的观点，这与孢粉学和分子证据的分析结果一致；推测肖菝葜属和菝葜属的土茯苓组sect。

These results suggested that higher concentration of NaCl could cause the seed dormancy and accelerate the germination of ungerminated seeds. Perhaps there was a mechanism that the seed coat or embryo could prevent Na~+ from entering into the embryo so as to keep higher K~+ and lower Na~+/K~+ in the embryo. And it might be one of the physical mechanisms that the seed of Hibiscus hamabo Sieb.et Zucc. could resist high salinity stress. In addition, the annual seedlings of Hibiscus hamabo Sieb.et Zucc.

上述结果表明：高浓度的盐可以诱导海滨木槿种子休眠并促进盐胁迫解除后种子的萌发，这种机制可以使之避开不良的萌发条件，等到降雨使土壤溶液浓度降低再萌发，这是盐生植物的种子适应盐渍生境的一种有效方式；海滨木槿的种皮有阻挡Na~+进入胚的作用或胚具有某种拒Na~+的机制，使胚保持较高含量的K~+和较低的Na~+/K~+，这可能是海滨木槿种子耐盐的主要生理原因之一。

The value of the hardness of mung bean decreased as the soaking time increased. On the other hand, the hydration rate constant of mung bean increased, but the equilibrium of the moisture content decreased. Higher temperature could be conducive to reaching an equilibrium of the moisture content and shorten soaking time. On the microstructure, observation soaking could promote mung bean seed coat to absorb water, that might make its spongy mesophyll swell and inner wrinkly structure more smooth . During soaking at 50℃ and 70℃ for two hours, the surface and palisade parenchyma of the mung bean seed coat cracked, and pectic substances of the middle lamella were loss. Because of this, soaking rate could raise and shorten the soaking time.

在硬度测试中，则呈下降趋势；在绿豆吸水特性方面，其吸水速率常数呈增加趋势，而水分平衡常数则呈下降趋势；浸渍温度之提升有助於达到浸渍平衡及缩短浸渍时间；配合绿豆微细构造之观察，种皮会因浸渍、吸水，种皮外表的多角形海绵组织会有膨大情形，内部皱摺状构造则渐趋平滑；在50℃、70℃浸渍二小时，绿豆种皮之表皮、栅状组织会有破裂，海绵组织及中胶层果胶会有流失情形，因而使绿豆之浸渍速度提升与缩短浸渍时间。

The UBC-868 is the most efficient primer which generates 16 polymorphic bands, including the most significant 900 bp polymorphic DNA fragment. The 900 bp fragment is specifically observed in vegetable soybean varieties which have black seed coat, except the yellow seed coat variety Kuo China.

其中以UBC868扩增出16个DNA条带为最多，且於电泳胶片上900 bp处有一明显的多型性条带，此DNA条带除了来自中国的Kuo China品系外，可视为常出现在黑色种皮毛豆中。

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。
