小麦赤霉病

In this experiment the validity of SSR markers Xbarc 133, Xgwm 493, Xgwm 533a and their combinations in the molecular marker assisted selection in Fusarium head blight resistance breeding in wheat was studied.

本研究探讨了与小麦抗赤霉病QTL紧密连锁的SSR标记Xbarc 133、Xgwm 493、Xgwm 533a在育种早代材料中辅助选择的有效性。

It is suggested that the combination of SSR markers Xbarc 133, Xgwm 493, Xgwm 533a be used in the Fusarium head blight resistance breeding in wheat.

建议小麦的抗赤霉病分子标记辅助育种选用Xbarc 133、Xgwm 493、Xgwm 533a三标记一起进行筛选。

The resistance of wheat to scab mainly showed partially dominant effect.

小麦对赤霉病的抗性主要表现为部分显性。

The study on structure of wheat PGIP lay the foundation for the elucidation of its mechanism, and is significant for breeding crops resistant to Gibberella zeae Schw.

小麦PGIP的结构研究为进一步弄清其作用机理打下了基础，抗赤霉病基因工程具有重要意义。

In this research, using the Oligosaccharides derived from plant cell walls as inducers, we examined whether they can induce the resistance to powdery mildew, head blight and stripe rust of wheat.

本研究以自行设计的方法从植物细胞壁中提取低聚糖，以其为诱导剂，研究其对小麦白粉病、赤霉病和条锈病的诱病导抗性效果。

Oligosaccharides could induce obvious resistance to powdery mildew, head blight and stripe rust of wheat. However, the effects on different diseases are quite different due to Oligosaccharides derivation, time for enzyme extraction and the concentration used.

研究表明，所用提取物可以诱导小麦产生对白粉病、赤霉病和条锈病的抗性，但不同来源、不同的酶解时间和不同使用浓度的低聚糖在不同病害上的诱导抗病性效果差异很大。

The results showed that one protein peak (designated P0) was bigger in resistant varieties When the sample were inoculated with spores or H202, but no difference in susceptible varieties, so protein P0 was related to wheat resisting Fusarium head blight.

结果表明，所有抗性品种在用病原物接种或过氧化氢处理后，蛋白质P_0的吸收峰明显增高，而在感性品种中差异不明显，P_0是与小麦抗赤霉病相关的蛋白。

At last,PCR detection techniques to another three important diseases(wheat sheath blight,wheat loose smut and wheat scab) were studied.

此外，还研究了针对另三种重要小麦病害(纹枯病、散黑穗病和赤霉病)的PCR检测技术。

Powdery mildew and scab are serious wheat diseases occurring worldwide.

小麦白粉病和赤霉病是世界小麦生产中的严重病害。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
