The biological characters of p5CS-bar gene transgenic wheatgrasse and control plants were observed and analysed that none but caudex have marked differences(0.05); The values of plant height、spike length、spike width and stem/leaf are less than control plants, leaf length and leaf width are more than control plants; Under the same condition of growth and climate to compare transgenic wheatgrass with control plants we can see that trning-green sage is advance, defer procreate period, long viridity period, growth speed become slow and the figure of curves is"S", more tillers.

2对转p5CS-bar基因冰草阳性植株和阴性对照植株进行生物学性状观测比较，分析得出：只有丛茎差异显著，显著水平为0.05；株高、穗长、穗宽和茎叶比的值均稍小于对照，叶长和叶宽的值稍大于阴性对照；在栽培、气候相同条件下，返青期相对提前，生育期推后，青绿期延长；生长速度变缓，在整个生育期呈"S"型生长曲线；分蘖能力增加。

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.
