Changes of DBE activity of four cultivars had a single-peak curve, and the peak appeared in 14 d after anthesis. HPLC analysis showed that the activity of DBE to amylopectin was similar. There are two types of DBE in the wheat grains, one is isoamylase, and the other is limit dextrinase.

在灌浆过程中，淀粉去分支酶的活性均呈单峰曲线变化，灌浆中期活性最大；淀粉去分支酶对底物支链淀粉均具有相似的酶解活性；对灌浆中期小麦淀粉去分支酶进行的纯化结果表明，小麦籽粒胚乳中也存在2种类型的淀粉去分支酶，一种是以极限糊精为特异性底物的极限糊精酶，另一种是以支链淀粉为底物的异淀粉酶。

The unconditional and conditional analyses of genetic models and the corresponding statistic methods, including endospermic, cytoplasmic, and maternal plant genetic systems, were used to analyze the genetic relationships between protein content and the appearance quality traits of indica rice (Oryza sativa L.).

应用包括胚乳、细胞质和母体植株基因的遗传主效应以及基因型×环境互作效应的数量性状遗传模型及非条件和条件分析方法，研究了籼稻稻米蛋白质含量与外观品质性状间的遗传相关性，进一步揭示了籼稻糙米重、稻米直链淀粉含量对稻米蛋白质含量与外观品质性状间遗传相关性的影响。

Thus it is presented an effective RNA extraction method based on the nuclease adsorbent macaloid, poly vinyl pyrrolidone, and high concentration of KAc and ethylene glycol monobutyl ether, which has successfully extracted high-quality RNA from many materials difficult to RNA isolation, such as RNase-rich rabbit liver, plant and microbial tissues rich in polysaccharides, lipids and polyphenol compounds.

现利用硅藻土对RNase的吸附性，结合PVP、高盐及乙二醇丁醚沉淀等处理，建立了一种广泛适用的RNA提取方法。在富含多糖的玉米胚乳，富含RNase的动物肝脏，多酚多油脂的银杏、麻疯树以及木霉、酵母等10多种RNA提取困难的动、植物与微生物材料中都提取出完整性好，得率高的RNA。

In a giving stage after pollination,p53 homologue showed high levels in the antipodal cells,integument,immature endosperm,ovary wall,tracheary elements,and aleurone layer,while c-myc homologue showed low levels in these tissues,only before pollination showed high expression in polar nucleus.

结果发现，在授粉后的一定阶段，在反足细胞、珠被、未成熟的胚乳、子房壁、导管组织和糊粉层中，p53同源基因表达强烈，c-myc同源基因的表达相反，在授粉后的这些组织中基本不表达，而在授粉前的中央细胞的极核中表达水平较高。

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。

Compared to other elements content in different parts of different genotypes of wheat grains, we can find that there was extremely remarkable linear relations between the content of Pb and Cd

植物受重金属的污染往往是多种重金属的复合污染[15]，通过比较不同基因型水稻籽粒同一部位和不同部位Cd含量的差异，发现对Pb、Cd积累的部位差异是一致的，均是糊粉层累积最多，内胚乳最少。

The Plant tissue raise is the plant sterile culture technology, has the totipotency theory according to the vegetable cell, the use plant body exsomatize organ (for example root, stem, leaf, stem point, flower, fruit and so on), the organization (for example cambium, epidermis, cerebral cortex, marrow department cell, endosperm and so on) or the cell (for example big spore, small spore, somatic cell and so on) as well as the protoplast, in aseptic and suitable artificial culture medium and illumination, temperature and so on under artificial condition, can induce injuries the organization, not to decide the bud, the adventitious root, finally forms the complete adult plant the discipline.

植物组织培养即植物无菌培养技术，是根据植物细胞具有全能性的理论，利用植物体离体的器官(如根、茎、叶、茎尖、花、果实等)、组织（如形成层、表皮、皮层、髓部细胞、胚乳等）或细胞（如大孢子、小孢子、体细胞等）以及原生质体，在无菌和适宜的人工培养基及光照、温度等人工条件下，能诱导出愈伤组织、不定芽、不定根，最后形成完整的植株的学科。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
