种子

Seed pods of Ibicella lutea, Martynia annua, and Proboscidea parviflora. No one has accused Martynia annua of being a carnivore. It just has shady relatives. Note the very spiny pod of Ibicella lutea and rather smooth pod of Proboscidea parviflora.

网站第二张图是三种植物的种子）左边的黄花单角胡麻种子布满棘刺；中间的 Martynia annua 并无列入食虫植物，它只是和亲戚长得有点像罢了；右边的 Proboscidea parviflora 种子则较为平滑。

To understand the adaptability and ion regulation mechanisms of Medicago sativa, Melilotus officinalis, and Astragalus adsurgens seeds at their germination stage to saline environment, the seeds were treated with different concentrations of NaCl, and their germination rate and recovery germination rate ere determined. In the meantime, the changes of main ions contents in seed embryos and the water uptake by the embryos at 400 mmol L^(-1) of NaCl were investigated.

试验对3种豆科牧草紫花苜蓿、草木樨、沙打旺的种子，在萌发阶段对盐渍环境的适应性和离子调控机制进行了研究，测定了盐渍环境中种子的萌发率和恢复萌发率；同时，对400mmolL^(-1)NaCl处理后，种子恢复萌发、胚的主要离子含量变化、水分吸收等情况进行了测定。

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。

But when we examined the structure of cultivar of D. huoshanense, endomycorhiza was founded unexpectedly. And in the wild type of D. huoshanense, fungi was also founded in its stems and leaves. So the author thought that endomycorhiza is not only located in the roots of Dendiobium plants, but also exists in other organs of plants, including stems, leaves. As plant produces seeds, mycorhiza could enter into the cells of seeds. When mature seeds germinate in media, the endomycorhiza enter into the roots of cultivar.

石斛属植物与真菌共生，根为菌根，作者在研究霍山石斛组织培养型结构时发现，组织培养苗的根部也分布有真菌，而且在野生霍山石斛的茎、叶中发现有真菌，作者因而指出，真菌并不是完全分布在根部，而是遍布于整个植物体，推测植物形成种子时，真菌进入种子，所以在组织培养时，真菌随着种子的萌发，进入植物体根部。

With Zhonghuang 35 as tested materials, the seed germination experiments of soybean were carried out by using 0.01, 0.10, 1.00 and 10.00 mg/L NAA. After culture for 7 d, the germination rates and the lengths of plumular axis, radicle as well as germ of soybean seeds were measured to compare the effects of NAA with different concn. on the plumular axis length and hypocotyls-radicle ratio when the soybean seeds germinated.

方法］以中黄35为供试材料，采用不同的NAA浓度(0.01、0.10、1.00、10.00 mg/L)对黄豆种子进行萌发培养试验，培养7 d后分别测量黄豆种子的萌发率以及胚轴、胚根和胚芽的长度，比较不同浓度的NAA对黄豆种子萌发时的胚轴长、胚轴胚根比的影响。

On the other hand, the crude extracts of Sapindus mukorossi could not inhibit the seed germination on Pak-choi, but their n-BuOH fractions could retard the germination for 36 h.

至於植物相克作用活性方面，由小白菜种子发芽抑制试验结果得知，无患子木材与果实抽出物各分离部皆无法抑制种子的发芽，但二者之正丁醇分离部均可延缓种子发芽作用36 h。

The seed germination rate, germination speed and radical length were determined to study the effects of distinct temperature on the germination of Stachys 'Silver Carpet' seeds collected in two different years.

研究不同温度对不同年度采收的银水苏种子发芽特性的影响，对种子发芽率、种子发芽强度及胚根长度进行了测定分析。

The experimental results shows, if the ratio between MS-1 and OP-10 rangs from 1:1 to 3:l,and the total dosage of them is about 20% of Octamethylcyclotetrasiloxane (D4 ) in quality, we can obtain a kind of stable seeded emulsion of organic silicone modified acrylic ester emulsion. At the same time, if the ratio between MS-1 and Tetramethylammonium Chlorideis l:1.7,the total dosage is about 50% of D4 in quality; the ratio between MS-1 and Cetyltrimethylammonium Chlorineis 7:1, the total dosage is about 25% of D4 in quality,we can also obtain stable seeded emulsions. But if the complex emulsifier system is made of TMAC and OP-10, MS-1 and Peregal O or CTAC and Span-80, we can not synthesize any kind of satisfactory seeded emulsions.

实验结果表明：当MS-1与OP-10的质量比为1：1～3：1，总用量为八甲基环四硅氧烷(D_4)的20％左右时，可合成稳定性良好的硅丙种子乳液；MS-1与四甲基氯化铵的质量比为1：1.7，总用量为D_4的50％左右，MS-1与十六烷基三甲基氯化铵的质量比为7：1，总用量为D_4的25％左右时，亦能得到稳定的硅丙种子乳液；而TMAC与OP-10、MS-1与Peregal O以及CTAC与Span-80的复合体系作为乳化剂时均不能得到满意的硅丙种子乳液。

Water uptake by seeds rapidly increased with imbibition, and did not exhibited a typical triphasic pattern of water uptake. Rate of electrolyte leakage and relative leakage from seeds dramatically increased up to 3 h of imbibition, and then declined. The time and thermal time required for 50%germination seeds were 5.5 h and 7 degree days, respectively.

在吸胀过程中，种子含水量迅速增加，不表现出典型的吸水三阶段模式；种子的电解质渗漏速率和相对电导率显著增加直到3 h，然后下降。50％种子萌发需要的时间和热时间分别是5.5 h和7℃d。

Percentage of seedling in hexaploid Tritical X common wheat was more high because endosperm developed very well than that in common wheat X hexaploid Tritical because endosperm developed bad. Many seeds and good seedling were obtained by back-crossing.

2六倍体小黑麦×普通小麦与普通小麦×六倍体小黑麦两种杂交方式都有比较高的杂交结实率，但前者种子发育好，种子相对饱满，出苗率高，后者种子胚乳发育不良，出苗率低。
