The large stem and loop structure can be constructed from the sequence surrounding the 5' and 3' ends of the 16S rRNA gene.The stem is about h alf shorter than that of tobacco,due to a 79 bp deletion in Brassica napus chlor oplast.

5%、96.1%。油菜叶绿体16SrRNA基因5＇端上游及3＇端下游的顺序能互补而形成一个较大的茎环结构，但与烟草相比，由于3＇端下游顺序有79bp的缺失，因此，该结构中的茎部分大小仅为烟草的二分之一。

The reliability reached 60%. So, it could be thought Kanamycin daubing vane and dipping seeds were ideal methods for fast screening transgenic rapeseed and descendant's heredity analysis.

因此可以认为卡那霉素涂抹叶片和浸泡种子两种方法是转基因油菜进行大规模、快速的筛选及后代的遗传分析的理想方法。

The reliability reached 60%. So, it could be thougnt Km daubing vane and dipping seeds were ideal methods for fast screening transgenic rapeseed and descendants heredity analysis.

因此可以认为叶片涂抹和种子浸泡两种方法是油菜转基因进行大规模、快速的筛选及后代遗传分析的理想方法。

This review does not describe this research topic in detail, but the use of transgenic medicinal plants of Lycopersicum esculentem, Daucus carota, Solanum tuberosum, and Brassica napus has been reported.

这项检讨工作，并不说明这一研究课题细节，但使用转基因药用植物的lycopersicum esculentem ，胡萝卜，马铃薯，甘蓝型油菜已报警。

A complete diallel of seven yellow-seeded rapeseed lines as sample which come from different sources by using canonical correlation approach was carried out.

以7个不同遗传来源的甘蓝型黄籽品系所配制的完全双列杂交作样本，对甘蓝型黄籽油菜进行典型相关分析。

The results of the herbicidal effects study display that 1,4-dioxoquinoxaline formaldehyde-salicylic aldehyde dihydrazone and 1,4-dioxoquinoxaline formaldehyde acetone dihydrazone have obvious herbicidal activity.

研究结果表明1，4-二氧喹喔啉-2-甲醛-水杨醛双腙和1，4-二氧喹喔啉-2-甲醛-丙酮双腙表现较明显的活性，在500mg/L浓度时对稗草的株防效分别为51.3%和55.0%；对油菜株防效较弱，分别只有33.5%和17.5%。

Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现&低促高抑&的规律，且茎叶浸提液作用效应大于根系浸提液。
