繁殖

This paper deals with the influences of Hg to the morpha. some physiological and biochemical parameters such as chlorophyll, superoxide dismutase, catalase of a kind of submerged macrophyte Egeria najas; some parameters for the amelioration of water quality and agamogenesis of Egeria najas were also studied.

本文研究了Hg~(2-)对沉水植物细叶蜈蚣草外部形态、叶片叶绿素含量、超氧化物歧化酶和过氧化氢酶活性等几个生理生化指标的影响：从水体主要理化指标和生物营养元素的变化情况研究了Hg~(2 )对细叶蜈蚣草净水功能的影响；从细叶蜈蚣草断枝和侧枝生殖的变化情况研究了Hg~(2 )对其营养繁殖的影响。

However, yet the male agaric fruiting body is difficult to plant, but its mycelium could be planted on the artificial culture medium, and this myvelium does not have any request to the culture medium ,the mycelium grows vigorously on the culture medium.

然而，虽然桑黄子实体栽培困难，但其菌丝体却能够在人工培养基上生长繁殖，而且该菌对培养基的理化性质并无特殊要求，在营养丰富的培养基上菌丝长势旺盛、浓密。

Because of the exotic weeds with strong reproductive capacity, adaptability and adversity-resistance, and short of strong competitive plants and natural enemies in the local area the exotic weeds such as Aiternanthera philoxeroides, Eichhornia crassipes, Ageratina adenophorun and Ageratum conyzoides etc.

由于农林牧渔业生产、绿化美化等目的有意引进；或旅游、交通工具等无意引入；或自身扩散传播的自然入侵，外来植物一旦逃逸人为控制进入自然生态系统并能自行繁殖和扩散，形成野化种群，变成外来入侵植物，成为危害农牧业生产和破坏生态环境的有害杂草。

That bind to specific carbohydrate groups on the plasma membrane of cells, used in the laboratory to stimulate proliferation of lymphocytes and to agglutinate red blood cells.

This method is called air layering.

这种繁殖方法叫高压取条法。

This picture shows the reason why we propagate maple cultivars by vegatative f ashion, cuttings, air layering, and grafting, mostly by grafting.

此张照片可看出为何我们利用植株切割，压条，嫁接方式来繁殖枫木以培育新品种，比较A.p。

This picture shows the reason why we propagate maple cultivars by vegatative fashion, cuttings, air layering, and grafting, mostly by grafting. See the leaf shape and color of the A.p.

It is very important to remember that Alaskan Malamutes are a working breed .

这是很重要的是要记住，阿拉斯加马拉慕是繁殖工作。

When the cell density scale of the algae was 1000 cell/mL, the algaecide could restrain the growth and propagation of the algae only with the concentration of 0.05 mg/L.

实验发现，藻细胞密度为1000 cell/mL时，0.05 mg/L的异噻唑啉酮即可以完全抑制藻细胞的生长繁殖。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
