The effects of safener on the growth and ALS activity were also examined. It showed that low concentration of AE F107892 could stimulate the growth of s-18 cultivars, but had little effect on the r-6 cultivars. High concentration of AE F107892 could inhibit the growth of both of the two cultivars.

测定了安全剂对小麦生长及ALS活力、GSH含量和GST活性的影响，结果表明：低浓度安全剂刺激敏18号小麦的生长，对抗6号的影响则较小，高浓度则都抑制了小麦幼苗的生长。

Safener increased the ALS activity and it also increased the GST activity of the two cultivars, which may enhance the metabolism of the herbicide, thus increased the tolerance to mesosulfuron.

本研究认为不同小麦对甲基二磺隆的敏感性不同，其敏感性可能与靶标酶ALS有关，安全剂提高了小麦ALS活力，也提高了GST的活力，增强了除草剂的代谢，从而增加了小麦对甲基二磺隆的耐药性。

The plasmid pDM803, carrying the bar gene, conferring resistance to the herbicide, and the screenable uidA gene, was transferred into wheat by particle bombardment.

在此基础上，将含有bar基因和GUS报告基因的质粒pDM803用基因枪法转化小麦，获得可育的转基因小麦植株，从而建立了适于中国春性小麦基因型的基因枪转化体系。

Improved high ionic strength medium was adopted to extract the cpDNAs of Yunnan wheat,Tibet semiwild wheat and two cultivars of common wheat (Chinese Spring and Een 1).Restriction fragment analysis of cpDNAs was carried out with the use of 7 restriction enzymes.

亚种。我们采用改进的高离子强度法，提取云南小麦、西藏半野生小麦、普通小麦的两个品种(中国春和鄂恩1号)的叶绿体DNA，并用7种限制性内切酶对它们的叶绿体DNA进行了酶切图谱分析。

In the west of China.Improved high ionic strength medium was adopted to extract the cpDNAs of Yunnan wheat,Tibet semiwild wheat and two cultivars of common wheat (Chinese Spring and Een 1).Restriction fragment analysis of cpDNAs was carried out with the use of 7 restriction enzymes.

Yunnan wheat(Triticum aestivum ssp. Yunnanense King) and Tibet semiwild wheat (Triticum aestivum ssp. Tibetanum Shao) are two endemic subspecies of common wheat T. eastivum L.

云南小麦(Triticum aestivum ssp.yunnanense King)和西藏半野生小麦(Triticum aestivum ssp.tibetanum Shao)是我国西部地区特有的两个普通小麦T.aestivum L。

Yunnan wheat(Triticum aestivum ssp. Yunnanense King) and Tibet semiwild wheat (Triticum aestivum ssp. Tibetanum Shao) are two endemic subspecies of common wheat (T. eastivum L.) in the west of China.

The inhibition substances in Sorbus pohuashanensisHedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection.

在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。

Soaking seed of rice and wheat with zymolytic liquid of Trichoderma harziaiarum, Trichoderma DWC and Trichoderma viride, comparing with germinate ratio, germinate force, root length, bud length and ratio of root to bud, the results show that 50 times dilute zymolytic liquid of Trichoderma harziaiarum has a relatively notable promote role for germinate of seed .The effect of Trichoderma viride to germinate of seed is not evidence. Trichoderma DWC for seed sprout has certain inhibition.

据此，采用哈茨木霉作为出发菌株，通过离子束诱变，从大菌落株中筛选出促进生长的高产突变株——h-13菌株，通过对用该菌株发酵液处理后的水稻及小麦的种子的各项生理生化指标的测定，发现该菌株比其它菌株更能促进水稻和小麦的活力和发芽率，三天时小麦的总根长为3.03cm，比对照的1.42cm的两倍还多，并且能够明显提高种子发芽后的淀粉酶和蛋白酶的活力，其活力都是对照的两倍左右。

Then by the tracking investigation of the herbicide resistance of generations crossed or backcrossed with Bar gene transgenic wheat and the wheat hybrid descents heredity performance were studied. The result indicated that: 1 Development of regeneration systemsWheat genotypes and medium are the key factores influencing the development of regeneration systems for immature embryo cultivation.

此外通过回交将抗Basta除草剂的Bar基因转育到这些小麦品种，通过对转Bar基因小麦人工杂交与回交后代除草剂抗性的连续跟踪鉴定，研究了Bar基因在小麦杂种后代的遗传表现。

I can not make it blossom and suits me

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
