对西藏藏南农牧区5个地区的主要农作物冬小麦、春小麦、冬青稞、春育稞及春油菜品种的品质分析结果表明，与黄淮麦区渭河川地副区小麦品种相比，西藏小麦品种千粒重高、容重低、蛋白质及湿面筋含量极低，面团的流变学稳定性很差，面粉品质差，且不同品种之间品质差异较小；西藏青棵千粒重高、容重大、蛋白质含量极低，品种之间的差异小于地区差异；西藏春油菜菜籽含油量高，硫代葡萄糖甙含量低，但芥酸含量远超过国家规定标准。

The results showed that: 1 under the hydroponic culture established in this research, the experimental wheat plants grew well andperformed the typical architecture responses when exposed in Pi deprivation. Hemi-qantitative RT-PCR revealed that the transcriptional level of known P response gene changed dramatically; 2 In general the length of wheat root axis and the root/ shoot ratio arose when the Pi supply was deprived, however, the change models differed among different wheat genotypes. The investigation on their molecular basis would offer the useful clue for seeking high phosphorus efficiency protoplasma and gene resources of wheat.

结果表明：1在研究建立的小麦水培体系中，小麦植株生长正常并对磷饥饿胁迫条件做出发育形态建成水平的反应；半定量RT-PCR分析显示在此体系中小麦磷响应基因也在转录水平上产生显著变化；2在水培条件下不同基因型小麦对磷饥饿胁迫的反应总体上表现在根轴长度和根冠比有所提高，但不同基因型小麦的反应特点有差异；对这些反应特征的分子机理的深入分析可为有效筛选磷高效小麦新种质以及发掘磷高效基因资源提供线索。

The hybrid's biological characters are between wheat and wheat grass, but are more closel to wheat because the hybrid was backcrossed twice by wheat.

结果表明，BC2 F2的生物学特性处于小麦和小麦草之间，但更趋向于小麦，这是由于杂交后代经2次回交所致。

The changes of nitrogen content, free amino acid, C/N ratio and chlorophyll content of wheat in wheat-faba bean intercropping system were studied by pot experiment with 3 N levels 0, 75 and 150 mg Nkg^(-1 soil. The results showed that leaf nitrogen content of intercropped wheat was higher than that of monocultured wheat at 3N level at tilling and booting stages, but was lower at heading stages.
