In order to increase germination ratio of the seeds, enhance stress-resistance of seedling, accelerate popularization of variety, improve quality of turf, this experiment adopted chitosan of different concentrations to deal with the Dichondra repens Forst.

为了提高马蹄金种子的发芽率，增强植株的抗逆性，加速品种推广，改善草坪质量，采用不同浓度壳聚糖溶液处理马蹄金种子并进行萌发和栽培试验。

To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.

综上所述，我们首次报道不仅可从人胚胎的关节软骨中获得间充质干细胞，而且软骨来源的间充质干细胞除具有骨髓来源的间充质干细胞的多向分化能力外，还具有其来源的软骨组织特异性，那么，其作为软骨组织工程的种子细胞要优于骨髓来源的间充质干细胞，从而首次提出了一种新型的软骨组织工程的种子细胞，对于未来的软骨组织工程的临床应用提供理论依据。

For some seeds a long dormancy is a result of the extremely hard outer coating of the seeds.

对一些种子长期休眠现象，是由于极难外层涂料的种子。

Among of these, the research of TEHV has taken positive progress,but the research of EHT just started recently ,it is still facing a series of problem.At first,it is the selection of planting cells,how to take high degree of purity about cardiomyocytes should be overcome;Second,it is the selection of scaffolds,the biomechanical properties of scaffold been used still can,t meet the requirement.

首先是种子细胞的选择，如何获取纯度较高的心肌细胞，还需从各种种子细胞中进行筛选；其次是支架材料的选择，目前应用的材料在生物力学特性上还不能满足临床使用的要求，还无法承受左心室巨大压力的冲击，因此还有待进一步的研究和改进。

The botanical characteristics and biological characteristics of DeHong Elephant grass and King grass were observed and compared.

通过对德宏象草和王草的植物学特征、生物学特性进行观测比较，结果表明：德宏象草种子实生苗生长速度快，其自然扩展蔓延途径主要依靠种子繁殖进行；德宏象草的干物质产量、主要营养成分均极显著高于王草P。

The research on the reservation of the seed bank in soil and the biological .diversity of weeds in teaching practice base for silkworms of Shengyang Agriculture University was done in their germination and elutriation,with Simpon index and Shannon-winner.

通过目前最常用的杂草种子库研究方法—诱萌法、淘洗法，运用生物多样性Simpon指数和Shannon-winener指数对沈阳农业大学桑蚕教学实习基地土壤种子库的储量和多样性格局进行研究。

A minute structure in seed plants,containing the embryo sac and surrounded by the nucellus,that develops into a seed after fertilization .

胚珠种子植物的一个小的结构，含有胚囊并被珠心所包围，施肥后长成种子受精的产物是杂合子。

The results showed that endocarp had no effect on the seed germination, physical barrier of endocarp and some endogenous inhibitor in the seed synthetically resulted in seed dormancy.

结果表明：内种皮对种子萌发没有影响，其种子休眠是由于核壳的机械障碍和内源抑制物的综合作用。

Dormancy break and germination of both seeds are accompanied by a decrease of ABA content in endocarp and seed coat, and by an increase of GA4 content in embryo.

山樱花和杨梅种子的休眠性质均属於生理休眠，种子的休眠解除和发芽皆需要伴随著种皮和内果皮的内在荷尔蒙ABA含量的降低和胚内GA4含量的增加。

The experimental results of pump threshold, energy conversion efficiency and beam divergence of the first stokes are present.
