The results suggested that the activities of these enzymes quickly enhanced at 1 d, 3 d, 5 d and 7 d after inoculation by injecting conidia of the false smut fungus at 7-10 d before heading in the resistant cultivars, but slower increase in the susceptible cultivars, and also showed that there was correlations between the cultivar resistance to the disease and the three enzymes.

结果表明，在抗病品种中苯丙氨酸解氨酶、过氧化物酶和多酚氧化酶3种酶活性接种后迅速提高，变化幅度较大；而感病品种的酶活性在接种后缓慢增加，变化幅度小。由此说明，这3种防御酶与水稻抗稻曲病有一定的关系。关键词水稻；稻曲病；防御酶

Composition of low molecular weight glutenin subunits and gliadins were investigated with thirty common wheat cultivars which are widely grown in Shangdong province. In our study we used acid polyacrylamide gel electrophoresis and SDS-polyacrylamide gel electrophoresis, analysed Sedimentation test, Protein content, Mixing time, Stability, Max-resistance to extension, Farinograph Quality Number and Extensogram area of the 30 common wheats. They have close relationship with the technology properties of noodle wheat cultivars.

本研究通过酸性聚丙烯酰胺凝胶电泳和SDS-聚丙烯酰胺凝胶电泳，分析了30个山东省种植面积较大且具有部分代表性的普通小麦品种的低分子量麦谷蛋白亚基和醇溶蛋白组成，测定了30个品种的蛋白质含量、沉淀值、面团形成时间、稳定性、粉质评价值、最大拉伸阻力和拉伸曲线面积等面粉及面团主要品质性状，分析了低分子量谷蛋白亚基和醇溶蛋白组成与面条小麦品质性状的关系。

Measurement of some physiological factors related to salt-tolerance in wheat cultivars SW12 Using HPLC-ESI-MS technique, Glycinebetaine, proline and malondialdehyde in leaves, which collected from wheat cultivars SW12, Ningchun 4 and Chinese Spring exposed to salt treatments with concentration ranges of NaCl s of 0, 100, 200, 300, 400 and 500 mmol/L and sampling for 1, 3, 5, 10, 20 and 30 days, respectively, were measured.

小麦SW12耐盐种质生理指标测定 HPLC-ESI-MS分析表明，SW12和两个对照品种宁春4号和中国春在6个不同盐浓度（0、100、200、300、400和500mmol/L NaCl）和6个不同的盐胁迫时段中（1、3、5、10、20和30d），随着盐胁迫强度的增加，它们叶片组织中甜菜碱、脯氨酸和丙二醛的含量均有不同程度的增加，3个品种在5种不同盐浓度下，甜菜碱和丙二醛的含量存在很大差异。

These two varieties with strong salt-tolerance are suggested being used directly for wheat production in salinity regions.2. Measurement of some physiological factors related to salt-tolerance in wheat cultivars SW12Using HPLC-ESI-MS technique, Glycinebetaine, proline and malondialdehyde in leaves, which collected from wheat cultivars SW12, Ningchun 4 and Chinese Spring exposed to salt treatments with concentration ranges of NaCl s of 0, 100, 200, 300, 400 and 500 mmol/L and sampling for 1, 3, 5, 10, 20 and 30 days, respectively, were measured.

中国农业科学院博士学位论文摘要3、小麦SW12耐盐相关基因Ta一LDH的克隆利用eDNA一AFLP和RACE等技术，从430 mmol/L盐胁迫下的小麦SW12中首次分离出了一个醛脱氢酶类似基因的全长eDNA，命名为儿胡LDHoTa一乙DH含有1 948个核营酸，编码一条由509个氨基酸组成的多肤，在其3'端，距离终止子约235 bp处有一个明显的加尾信号序列。

Whether there is salt stress or not, the transpiration velocity of warm winter wheat cultivars NR9405 and Xiaoyan6 are smaller than that cold winter wheat cultivars of Shaan229 and RB6. These results indicate the lower canopy temperature of cold-type winter wheat is caused by the higher transpiration.

无论盐胁迫与否，NR9405和小偃6号的蒸腾耗水量和蒸腾速率均小于陕229和RB6；蒸腾耗水量大，带走的热量多，是冷型小麦冠层温度低于暖型小麦的主要原因。
