On the basis of observation on the incident and transmitted photosynthetically active radiation of the winter wheat canopy under the monoculture and intercropping ways, the diurnal change of interception photosynthetically active radiation, the relationship between IPAR and leave area index, and the shading of the winter wheat were studied.

文章摘要：通过对单作和间作种植模式下作物冠层入射和透射光合有效辐射的观测，研究了不同种植模式下冠层光合有效辐射截获量的日变化规律及其与叶面积指数的关系以及冬小麦对预留行的遮荫作用。

Our work reported here are aiming at improving nitrogen and water use efficiency in wheat/maize, faba bean/maize, pea/maize and soybean/maize intercropping through field experiment.The main results obtained were as the following:(1) Land equivalent ratio was greater than 1.0 for faba bean (Viciafaba L.)/maize (Zea mays L.) intercropping regardless of nitrogen fertilizer application or not. Based on grain yields production, LER of pea (Pisum sativum L.)/maize intercropping was over 1.0 in spite of nitrogen fertilizer application, while LER was higher than 1.0 only when nitrogen fertilizer was applied based on biomass production. However, LER in soybean (Glycine max L.)/maize intercropping was smaller than 1.0 both nitrogen applicationa and no nitrogen application. In wheat Triticum aestivum L.

本文通过田间试验，对小麦／玉米、蚕豆／玉米、大豆／玉米和豌豆／玉米间作种植下作物对氮素和水分利用的影响进行了系统比较，获得的主要结果如下：(1)蚕豆／玉米间作的土地当量比都大于1；豌豆／玉米间作以籽粒产量为基础的LER无论施氮还是不施氮都大于1，而以生物学产量为基础的LER只有施用氮肥时才大于1；大豆／玉米间作无论施氮还是不施氮LER均小于1。

This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.

证据主要来自以离体根尖为材料的实验：(1)通过检测干旱胁迫下小麦根尖NOS活性、O〓合成酶活性和ABA积累的时间变化进程，发现ABA积累滞后于ROS和NO的变化；(2)抑制剂实验表明，NO清除剂和NOS抑制剂可以抑制自然干旱胁迫及渗透胁迫诱导的小麦根尖ABA积累，ROS清除剂抑制自然干旱胁迫诱导的ABA积累而不抑制渗透胁迫诱导的小麦根尖ABA积累；(3)在非胁迫条件下施加外源的ROS或NO可以诱导小麦根尖积累ABA，ROS和NO之间具有协同作用。

The results showed that, using transient GUS expression, the frequency of resistant calli and shoot differentiation as a criteria, wheat mature embryos were cultured on the preculture medium of CM4C1P for 14 days, and immersed in inoculation suspension Ⅰ for 3 hours, then the explants were co-cultured under desiccation conditions for 3 days, which was optimal conditions for Agrobacterium-mediated transformation of wheat mature embryos.

为了进一步完善根癌农杆菌介导的小麦遗传转化体系，以小麦成熟胚为转化受体，研究了根癌农杆菌介导法转化小麦的主要影响因素，结果表明，以gus基因瞬时表达率、抗性愈伤组织获得率和分化率为转化指标，小麦成熟胚在预培养基CM4C1P上预培养14d后，用侵染培养液Ⅰ侵染3h，再经干燥共培养方式处理3d，是根癌农杆菌介导成熟胚转化的合适条件。

For understanding the yield and quality changes of spring wheat piled up in field after reaping in Qinghai province, we selected Qingchun 533, which was planted widely in Qinghai province, and Plateau 205(susceptible to preharvest sprouting), Plateau 115, Plateau 448 and Plateau 314 which were bred by our institute, piled up them as the quomodo farmer used, sampled them every nine days, and mensured yield, SDS sedimentation value and falling number value to trick the changes of wheat.
