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.

Nitrogen also increased the rate of wheat yield of intercropping single for Gao Yu, reflecting the presence of wheat intercropped with nitrogen from the beans to the transfer of wheat, resulting in intercropping conditions decreased the sensitivity of wheat to nitrogen fertilizer.

同时施氮增加小麦产量的幅度以单作高于间作，这反映了在小麦蚕豆间作体系中存在着氮素由蚕豆向小麦的转移，导致在间作条件下小麦对氮肥的敏感性下降。

The results shoed that after spraying 1 and 5 mgL^(-1) of anthraquinones, the photosynthetic rate raised by 38.03% and 39.73%, chlorophyll content increased by 3.53% and 3.83%, and MDA content decreased by 11% and 23%, respectively. The anthraquinones could absorb solar UV radiation, and convert the harmful UV into blue or yellow light which can promote plant photosynthesis. It as suggested that foliar-spraying appropriate concentrations of aloe's anthraquinones could promote wheat photosynthetic activity, alleviate UV harm, and thus, increase wheat yield.

结果表明：在灌浆期用浓度为1和5mgL^(-1)的芦荟蒽醌类物质喷施小麦，光合作用速率分别提高了38.03%和39.73%；叶绿素含量分别提高了3.53%和3.83%，丙二醛含量分别降低了11%和23%；蒽醌类物质能够吸收太阳中的紫外线，并将紫外线转换成能促进光合作用的蓝光或黄光；芦荟蒽醌类物质能促进小麦光合作用效率，减轻紫外线对小麦的损伤；喷施合适浓度的芦荟蒽醌类物质能够提高小麦产量。

The correlation coefficients of 12 of the 35 meteorological factors with wheat yield were significant at the 0.05 level. The precipitation during filling stage and winter wheat yield was significantly corelated, and the direct path coefficient was the highest, and it contributed the most to wheat yield, followed by the precipitation of elongating stage and turning green period. The evapotranspiration in April and May negatively correlated significantly with winter wheat yield at the 0.05 and 0.01 levels, respectively.

在与小麦产量相关的35个气象因子中，有12个因子的相关系数达到了显着或极显着水平，其中灌浆期降水与冬小麦产量呈极显着相关，且直接通径系数最高，对小麦产量贡献率最大；其次是拔节期降水量和返青期降水量；4、5月份的蒸发量与冬小麦产量密切相关，分别接近显着和达到极显着水平，它们对小麦产量形成起较大的负向作用；小麦越冬期间的气温也是不可忽视的气象因素。

To use the abundant cytoplasm resources in wheat alien species to improve wheat quality, five wheat lines of Chris carrying different types of Aegilops cytoplasm were used to conduct the direct and reciprocal crosses with four wheat varieties, which were widely adopted in wheat production, and the effects of the five different types of Aegilops cytoplasms on pentosan contents in F1 kernels were stndied.

为了利用小麦近缘野生种属的细胞质资源改良小麦品质，以山羊草属不同种异源细胞质的5种异质小麦品种Chris为材料，与生产上广泛推广种植的4个常规小麦品种进行正反杂交，研究了异源细胞质对其F1籽粒戊聚糖含量的影响。

With the Sand culture method, influences of different magnesium levels (0%、50%、100%、150%、200% and 300%) was explored to the wheat seedlings of different stages. Many targets such as plant height, root length, biomass, content of chlorophyll, activity of root, RGY, RGR and ratio of root to crown of the wheat were mensurated at the time of 7d, 15d and 30d of two leaves stage of wheat seedlings after their endosperms were removed at different magnesium levels.The results showed that different magnesium levels had unlike influences over the wheat seedlings.

以小麦为试材，采用砂基培养的方法，在镁浓度分别为对照组的0%、50%、100%、150%、200%和300%的营养基质上，培养剔除胚乳后的二叶期小麦幼苗7d、15d及30d，并分别测定该3个时间段小麦幼苗的株高、根长、地上部和地下部的生物量、叶绿素含量、根系活力以及相对生长速度、相对生长速率和根冠比等指标，研究不同供镁水平对不同时期小麦幼苗生长速率的影响。

In Argentina, where sowings are sharply lower than last year, dry weather slowed crop development, but rains improved prospects in Australia. The wheat consumption forecast is increased by 4m. tons to 643m., with feed use expected to reach a 17-year high of 111m.
