龙血树

Species animalcula were isolated from the wounds of Dracaena cochinchinenis stems. During culture period, the culture mediums or the mycelia of four species among the animalcula turned red, which is in some degree similar to the colour of dragon's blood. They were identified as Fusarium graminearum, and another unknown three species of Fusarium.

从剑叶龙血树茎干损伤部位及叶子斑块部位共分离得到24种微生物，其中有4种在培养时候，培养基或菌体本身不同程度的呈现红色，在一定程度上与龙血竭的颜色相类似，经鉴定，它们是Fusarium graminearm和三种未知镰刀菌属真菌Fusarium sp。。

Now the oldest living tree should be on the Polynesian Islands Dracaena it is said to have one there is more than 9000 years old.

现在还活着的最古老的树应该是波利尼西亚群岛上的龙血树吧，据说有一棵有9000多岁了。

Lifestyle and the excellent air quality doubtless play a part but legend links the mountain's power to the ancient Dracaena cambodiana trees that cover it.

生活方式和优秀的空气质量无疑是长寿的秘诀，但是古老的龙血树给这座长寿之山有增添了一份传奇色彩。

In addition, 11 mutants were also chosen form a commercial nursery. The main results are as follows: 1. It was the first time to conduct research on the germplasm innovation of Dracaena cambodiana.

首次对海南龙血树进行了种质创新途径的研究，田间自然变异的选择是目前最为有效的途径，组织培养分别结合EMS、60Co辐射和秋水仙素的诱变途径也是有效果的。

Like all companies we are always looking what other crops are interesting to do business in. In the past we had a large farm in Brazil to grow Dracaena propagation material which we exported to Holland where we sold it to the market.

就如同其他企业，我们一直不断找寻发展其它作物的机会，过去我们在巴西有生产龙血树属植物幼苗的农场，出口回荷兰，再销售到市场上。

特异性真菌作用于龙血树材质形成血竭的研究

Main Heteropanax has maple, Le Rhododendron engineering trees, Dracaena, Longbai modeling, engineering-oriented seedlings.

主营有幌伞枫、勒杜鹃工程树、龙血树、造型龙柏，工程苗木为主。

It is excreted from the dracaena plant's xylem after the xylem was injured by the outside force or intruded by the epiphyte, so it gains the recognition of the holy medicine on activating blood circulation.

血竭为一种传统名贵中药，它是龙血树属植物的木质部在受外力损伤或遭真菌侵入后分泌的红色树脂，被称为"龙血"，内服具有活血化淤、止痛等作用，外用具有生肌、止血、敛疮的功效，有"活血之圣药"的美誉。

Deodars, Douglas firs, casuarinas, banksias, gum-trees, dragon-trees, andother well-known species, succeeded each other far as the eye could reach.

喜马拉雅杉、洋松、&加苏林那&树、山茂、橡皮树、龙血树，和其他许多有名的品种，一棵接着一棵，一眼望不到头。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
