In the whole growth period of spring wheat, the response was different in yield and phase growing on climate change, such as the appearing time of sprouting, jointing, tasselling and maturity being ahead but milking being postponed. That is to say, it shortened the spring wheat's nutrition growth stage of seeding-sprouting, elongated the sprouting-jointing stage, cut down the generative growth in the jointing-tasselling phase, prolonged the tasselling-milking stage, and shortened the milking-maturity stage. These finally resulted in the shortening of whole growth period.

在春小麦整个生长发育过程中，其阶段生长和产量对气候变化的响应不完全一致：气候变化使该地区春小麦出苗期、拔节期、抽穗期和成熟期的出现时间均提前，而乳熟期出现时间推迟，导致播种－出苗期的营养生长阶段缩短、出苗－拔节期的营养生长阶段延长、拔节－抽穗期的生殖生长阶段缩短，抽穗－乳熟期的生殖生长阶段延长，乳熟－成熟期的生殖生长阶段缩短，最终造成全生长期缩短。

On the termination date, the cultured explants were all examined by Western blot, HE and transmission electron microscope. Our results showed that after 12-days in culture, the cultivation treated with AS-ODN reduced the synthesis of AMBN and had a deformed dental cusp with thinner enamel matrix. Ultrastructure analyses showed that there was hardly any cisternae of the rough endoplasmic reticulum in the ameloblasts at the tip of the cusp of AS-ODN treatedexplants. However, on average the enamel matrix was thinner compared with that in the control group. Furthermore, the collagen fibers in extracellular matrix were found disorganized. These findings seemed to provide a direct experimental evidence that tended to indicate that the arrested AMBN translation in cultured tooth germs might result in the delay of the tooth development.

经用Western蛋白印迹检测表明，所设计的反义核酸对AMBN InRNA具有良好的封闭效果并成功阻断了牙胚对AMBN的表达；在缺乏AMBN情况下，与对照组相比，实验组牙胚在体外可以继续生长发育至钟状晚期，出现成釉细胞和成牙本质细胞的分化，成釉细胞可以分化成为分泌期型成釉细胞，胞浆中缺少合成蛋白质所必需的粗面内质网和高尔基氏体，缺乏溶酶体，表明对蛋白合成和脚的能力降低；实验组牙胚有牙尖形成和基质分泌，但牙尖形态异常，基质形成减少，牙尖周围基质最厚处为O.6卜m，明显薄于对照组的5.spin，基质中胶原纤维粗细不等，排列稀疏， 3 第四军医大学硕士学位论文未见钙化现象，充分证明了AMBN在牙胚发育中参与釉质基质形成和矿化过程，影响胶原纤维和牙本质基质的合成，促进成釉细胞对蛋白质的合成和釉质基质蛋白降解。

The low rate (150 Mg kg/hm~2), the middle rate (300 Mg kg/hm~2) and the high rate (450 Mg kg/hm~2) were experimented to study the yield and qualities formation and growth of flue-cured tobacco under different magnesium fertilizer application.

Dead branches or knots in different sizes of tree was studied and different branch development phases of growth,suppression,death and self-pruning was analyzed to evaluate the effect that knot size and distribution impact on timber quality.Branch and knot dynamic models were developed using stand and tree variables.Based on multipleunit stepwise regression method, the individual tree growth model was established using forest and crown factors as the variable. The best taper equation model of Larix olgensis was bucking data of 130 sample trees selected in the studied area.
