The study on germplasm resource of Lonicera Caerulea L. was not much made abroard and many problems should be resolved.

国外对蓝靛果忍冬种质资源的研究时间也较短，尚不深入，许多问题尚待解决。

First established a germplasm pool of Lonicera Caerulea L in China and provided valuable breeding materials for future breeding work.

在国内首次建立了蓝靛果忍冬种质资源圃，为将来的育种工作提供了非常宝贵的材料。

The average contents of A, T, G and C were 14.1%, 16.1%, 30.2% and 39.6%, respectively, the contents of GC 69.8%） were obviously higher than those of AT. Using these primers, ITS-1 region can be amplified in other four Lutjanus species, but the lengths of ITS-1 were largely different between different species.

将此引物在笛鲷属其他4种鱼类中扩增，发现该对引物有很好的通用性；比较发现在不同种中ITS1存在着较大的差异，适合将其应用于分子系统学和种质资源方面的研究。

Many species distribute in Sichuan .so to study Mahonia in Sichuan is helpful to solve the problems of berberine provisions in Sichuan, even the whole country.

本研究在四川省范围内开展了广泛的十大功劳属植物种质资源收集工作，对收集到的资源进行了生物碱含量的定量分析，并对部分植物进行了组织培养研究。

Levels of genetic diversity within and among 8 natural populations of Mangifera persiciformis C. Y. Wu et T. L. Ming were analyzed by AFLP markers.

采用AFLP分子标记技术，对中国特有杧果野生近缘种扁桃忙种质资源8个居群的遗传多样性进行了研究。

In this context the wild mango germplasm at Lapuo County, Guangxi, China were studied by using their biological characteristics and the amplified fragments length polymorphism molecular marker. These wild mangoes were found morphologically similar to Mangifera indica; and the AFLP markers showed that at the similarity coefficient of 0.63, 92 mangoes including cultivars, Mangifera sylvatica Roxb., wild mangoes, Mangifera. Siamensis Warbg. were divided into 14 groups and that the wild mangoes at Lapuo were close to M. sylvatica Roxb. and M. siamensis Warbg., but remained to fall in the middle of the cultivars and could not be separated from them.

结果表明：那坡县野生芒果在形态学上与普通芒果较为相似；AFLP标记显示，包括部分栽培品种、林生芒果、广西百色那坡县野生芒果、泰国芒果等在内的92份芒果种质在相似系数0.63的水平上可分为14组，广西百色那坡县野生芒果虽然与林生芒果、泰国野生芒果等芒果属其它种较为接近，但仍处于栽培芒果的中间，不能与栽培芒果分开。

Xinjiang is the center of genus Medicago genetic resources in China.

利用这些种质材料培育的人工新品种共60个。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
