To explore the possibility utilizing mild drought treatment to promote metal ions absorption,uncontinuous drought treatment (1 h, 2 h, 3 h, 4 h each day, lasting for 8 days) and 24 h continuous drought treatment were adopted to wheat seedlings, Fe and Zn content in root, shoot, 1~3 leaves and relative water content in wheat leaves were detected to investigate the effect of different drought treatments on uptake and distribution of Fe and Zn.

中文摘要：为探讨利用轻度干旱处理促进金属离子吸收的可能性，采用液体培养法，研究了不同干旱处理方式对小麦幼苗Fe、Zn两种元素吸收和分布的影响。将10 d苗龄（3叶期）小麦幼苗分为5组，其中4组每天分别干旱1、2、3和4 h后复水，连续8 d，另外一组连续干旱24 h后复水，测定各处理的根、叶相对含水量和根、茎、第一叶、第二叶、第三叶Fe、Zn含量。

同时，通过秋水仙碱对四倍体小麦-节节麦杂种进行染色体人工加倍或利用未减数配子自然加倍，我国科学家创制了一些新的人工合成小麦。

Both the bacterial culture and aseptic filtrate showed activities to inhibit some pathogenic fungi including "Alternaria alternata", and "Fusarium graminearum" on activity plates assay. Antagonistic crude protein extract was obtained by 70% ammonium sulphate precipitation, and it was thermostable, unsensible to proteinase K and pepsin, and capable to induce the hypha lysis and cytoplasm condensation of "F. graminearum".

经平皿测试表明，多粘芽孢杆菌P-FS08菌株及其无滤液对烟草赤星病菌、小麦赤霉病菌等多种植物病原真菌均有抑制作用。P-FS08培养液通过70%硫酸铵沉淀得到具有拮抗活性的蛋白粗提液，其具有良好的热稳定性；对蛋白酶K和胃蛋白酶均不敏感；够使小麦赤霉病菌菌丝断裂，原生质浓缩。

It is well knonwn that water is unsufficient in North China plain, including Huang-Huai-Hai plain.

黄淮海平原是我国最大的平原，是我国小麦的主产区，随着经济与农业的发展，水资源严重不足已成为该地区小麦生产的重大威胁。

The bioassay indicated that some of them possess certain fungicidal activity against Botrytis cinerea, Gibberlla zeae, Rhizoctonia solani, Venturia nashicola at a dose of 50 μg/mL. The EC50 value of title compounds B-8、B-9、B-10、B-12 was reached 1.0, 0.2, 1.2 and 0.4 μg/mL against B. cinerea, the effect was approximated or better than pyrimethail and EC50 value of title compounds B-8, B-10, B-11 was reached 0.07, 0.2 and 0.05 μg/mL against G. zeae, the effect was better than carbendazim.

在50μg/mL浓度时，该系列化合物对番茄灰霉病菌Botrytis cinerea、小麦赤霉病菌Gibberlla zeae、水稻纹枯病菌Rhizoctoniasolani、梨黑星病菌Venturia nashicola菌丝生长均具有很好的抑制活性，其中化合物B-8、B-9、B-10、B-12对番茄灰霉病菌的EC50值分别为1.0、0.2、1.2、0.4μg/mL，接近或优于对照药剂嘧霉胺，B-8、B-10、B-11对小麦赤霉病菌的EC50值分别为0.07、0.2、0.05μg/mL，优于对照药剂多菌灵。

Uses the fuzzy mathematical generalization judgment law appraisal wheatvariety winter vernality and the mature period frequency ecology compatible question,after calculates MinB=0.1644, indicated in theresearch area wheat variety changeprocess the variety frequency reluctantly adapts the current climate ecologicalcondition.

使用模糊数学综合评判法评价小麦品种冬春性和成熟期频度的生态适应性问题，经计算MinB=0.1644，表明研究区小麦品种更替过程中品种生态型频度勉强适应当前的气候生态条件。

Inoculating test plants through vector,observing symptom and using universal primers(R16mF2/R16mR1)for phytoplasma 16S rDNA were conducted.1.4 kb DNA fragments were amplified by polymerase chain reactionin DNA samples extracted from inoculated wheat and viruliferous Psammotettix striatus L.respectively.

采用介体接种植物，症状观察和应用植原体16S rDNA基因通用引物对R16mF2/R16mR1进行PCR扩增，在接种小麦和传毒介体中均扩增出1.4kb的特异片段，鉴定出小麦蓝矮植原体新寄主7种。

The quality indices,including AWRC,GMP content,SDS sedimentation volume,Pelshenke fermentation time,Grain hardness,Starch content,Protein content,WEAX content,grain vitreousness,PPO activity,Mixing time of wheat samples from 28 cultivars planted in Anhui Province and 18 soft wheat cultivars from two locations were measured to determine their variance and conducted analyses of partial correlation,multi-regression and cluster.

测定了28个小麦品种的AWRC、GMP含量、SDS沉降值、Pelshenke值、硬度、籽粒总淀粉含量、籽粒蛋白质含量、WEAX、湿面筋含量、角质率、PPO活性、和面时间、峰高、7min尾高、7min带宽、形成角、衰落角、麦粉膨胀势、直链淀粉相对含量等19项品质指标；同时还测定了18个参试的软质小麦品种的一年两点试验的部分重要品质指标。

But theimprovement was still needed because of its late maturity and low grain-weight. The NChybrid is crossing with other vulgare so as to breed new NC hybrid suitable forproduction.

但在千粒重和早熟性上还有欠缺，目前正用其它普通小麦品种进行转育，以期培育出生产上能用的核质杂种小麦。

Than in China and will result in a much higher cost of the finished product. Therefore, a spike in wheat prices will have a larger impact on the loaf of bread in China than in the US.
