本文选择4类典型土壤（红壤、草甸棕壤、暗棕壤和栗钙土），以（小麦、白菜、萝卜、西红柿、大葱）为供试植物，进行了重金属（Cu、Zn、Pb、Cd）、有机氯、多环芳烃污染的植物种子发芽与根伸长抑制试验；植物早期生长试验研究；以草甸棕壤为供试土壤，进行了重金属（Cu、Zn、Pb、Cd）单一、复合污染条件下的蚯蚓急性毒性实验；以草甸棕壤、污染土壤和生物修复土壤进行蚕豆根尖实验和土壤原生动物实验。

Cd2+on the radicle growth of upland rice in low concentration that is manifested as a disincentive to roo...

Cd2+对旱稻幼根生长的影响，在低浓度下即表现为抑制作用，根长随Cd2+浓度的增加而递减。

Therefore, both the bioavailability and toxicity of selenate were greater than those of selenite under these experimental conditions.

小白菜根长、叶面积等生长指标均随Se和Se含量的增大而显著下降（p.01）；抑制小白菜根系生长的Se含量为60 mg·kg-1，明显高于Se含量（20.0 mg·kg-1）。

It was demonstrated that BDF-H16 was an gram-negative bacterium and had a bacilliform or arc bacilliform shape with a flagellum at one end.

结果表明：蛭弧菌BDF-H16为革兰氏阴性菌，杆形或弧杆形，端生一根鞭毛，菌体大小多为0.2μm～0.5μm×0.8μm～1.2μm；蛭弧菌BDF-H16对实验所选用的革兰氏阴性菌和部分革兰氏阳性菌均有裂解作用；以大肠杆菌为宿主菌，其最佳生长条件为宿主菌浓度6.75×10~9cfu/mL、pH7.0～7.5、温度28℃；在NaCl含量0.85%～5.00%的培养基中能够生长；恩诺沙星、诺氟沙星对其有抑制作用。

It was demonstrated that BDF-H16 was an gram-negative bacterium and had a bacilliform or arc bacilliform shape with a flagellum at one end.Its size was mostly 0.2μm～0.5μm×0.8μm～1.2μm.It had a wide prey area and could lyse all tested gram-negative bacteria and some gram-positive bacteria. The best lysis conditions to Escherichia coli were 6.75×109cfu/mL of prey bacteria concentration、pH7.0~7.5、28℃. It could grow in the solid culture added 0.85%~5.00% NaCl and was inhibited by enrofloxacin and norfloxacin.

Bipolaris sorokiniana may affect turf grass to cause leaf spot, bud rot, seedling blight, root rot, sheath rot. The temperature range of colony growth is 10～40℃, the optimum 25℃. Conidia can germinate in the temperature range of 20～35℃, and germinate best at 28℃; Conidia germinate well on slide water surface, contrary to other different methods, and they can germinate well under given air condition, but germination is not strict with nutrition. The inhibiting test of 8 kinds of fungicide showed Sporgon 50WP was most effective, and the inhibiting effect of the others was well to the conidia germination.

Bipolaris sorokiniana能浸染草坪禾草叶片形成梭形病斑，并可导致芽腐、苗枯、根腐、茎基腐、鞘腐等症状；病原菌在10～40℃下能够生长，最适生长温度为25℃；病原菌分生孢子在不同萌发条件中以水平萌发较好；分生孢子萌发需要空气条件，但对营养要求不严格；在20～35℃下分生孢子均可萌发，以28℃下萌发最好；八种不同药剂对病原菌的抑制效果表明，50%施保功可湿性粉剂1500倍液效果较好，其抑菌圈直径和抑制分生孢子萌发率分别为46.2mm和81.3%，其他几种药剂对孢子萌发也有较好的抑制作用。

Roots that arise in any other way are termed adventitious roots, for example those that develop from the stem in bulbs and corms.

在其它地方生长的根为不定根，例如鳞茎和球茎上的根。
