施硫可增加小麦的穗长、穗粒数，增加油菜单株结荚数、角果长和角粒数，从而增加了小麦和油菜的产量，施硫45 kg/hm2使小麦、油菜产量的增幅分别为6.5%~17.3%和

To improve the efficiency and application, pollen tube growth of different Brassica species is observed and factors of transformation are studied for optimization.

继而通过比较不同白菜型油菜、甘蓝和甘蓝型油菜品种的花粉管生长规律和转化率，得到表达报告基因的除草剂抗性植株，实现了不同类型和基因型油菜的高效转化，扩展了方法的应用范围。

The high quality of oil rape has been grown in Enshi since 1990s.Theplanting area increased rapidly from 1300 ha in 1994 to 30800 ha in 2005 which accountsfor 53.86% of the total production area of oil rape in the region.

恩施州自20世纪90年代开始发展优质油菜，且有一定规模，1994年双低油菜面积为0.13万hm~2，到1998年发展到1.50万hm~2，2005年发展到3.08万hm~2，占全州油菜生产总面积的53.86％，推广速度明显增快。

And the development and formation of the sieve tube elements of the different cultivars were influenced by the different levels of B: the sieve tube elements of the two cultivars were not formed at the level of 0.001mg/L; At the level of 0.01mg/L, the sieve tube elements of the high efficiency (Qingyou 10) cultivar could be formed, but the structure of the sieve tube elements was not complete, and the abruption and differenciation of the sieve tube elements of the low efficiency cultivar were inhibited, they were not formed; At the level of 0.01mg/L, the sieve tube elements of the two cultivars were formed.

不同硼水平下，不同硼效率甘蓝型油菜品种根尖筛管分子的发育与形成受到影响：硼浓度为0.001mg／L时，两个油菜品种都不能形成筛管分子；硼浓度为0.01mg／L时，硼高效品种青油10号筛管分子可以形成，但结构受到破坏，而硼低效品种Bakow筛管分子的分裂与分化受阻，几乎不可能形成成熟的筛管分子；硼浓度为0.5 mg／L时，两个油菜品种都能正常生长发育。

The results of histochemical GUS assay showed that no expression of GUSint was observed in Agrobacterium, with transient expression as high as 100% in cotyledonary node of Brassica napus L. after inoculated for three days. It not only verified that the vector was successfully constructed, bur also laid a basis for further increasing the stable transformation efficiency of other Brassica plants, and rapidly clarifying the function and pattern of expression and regulation of a unknown gene.

组织化学染色结果表明，GUSint在农杆菌中没有表达，而在接种3d的油菜中可高效瞬间表达，其中在子叶柄中瞬间表达率高达100%，这一方面证实载体构建成功，另一方面也为进一步优化油菜及其它芸薹属植物转化体系及在油菜中快速研究目的基因的功能和表达调控模式奠定了基础。

First, rape breed innovation must be strengthened , which can reduce die content of glucosinolate and erucic acid of rape breed and thus improve the per unit area yield and oil content of rape.

人世后我国油菜产业参与国际竞争的主要形式是通过发展我国油菜生产以减少对国外油菜及制品的进口。

The sterile and fertile plants of BC3 generation, derived from the hybridization between sterile line and restorer line and maintaining line, were detected by GISH-dcFISH. The observations showed that the fertile plants were all the Brassica napus-Xinjiang wild Sinapis arvensis monosomic alien addition lines, and the sterile plants had no Sinapis arvensis chromosome.

不育系分别与保持系、恢复系Nsa恢1、保持系杂交后获得了BC3代不育株及可育株，GISH-dcFISH分析结果表明，BC3代可育株为甘蓝型油菜－新疆野生油菜单体异附加系，而不育株中不含新疆野生油菜染色体。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
