Protein and starch are important in wheat quality and yield.To understand the genetic relationship between protein and starch at the quantitative trait locus (QTL)/gene level, 168 doubled haploid (DH) lines were used at three locations over 2 years.

基于动态拣选、出入库控制、包装状态和3D架口图像在内的物流管理过程可以为供应链管理带来更高的附加值,Kulmbacher啤酒厂就是通过引进SAP EWM/TM挖掘出这样的巨大潜力。在物流日常安排和行车线路规划方面也能使用户受益匪浅。由于IGZ公司转让了专利技术,因此后续推出的升级软件都可以由用户自主掌控。
利用化学诱变剂甲基磺酸乙酯(EMS)处理中品661获得株型突变体it1.对突变体从农艺性状、生理特性与细胞学观察、遗传分析及基因定位等方面进行了初步系统的研究.结果 显示株型突变体itl与野生型之间在株型结构上存在较大差异.与野生型相比,突变体株型紧凑,节间缩短,叶片变小呈深绿色且皱缩;突变体株高降低,但节间数目与野生型无显著差别,说明it1株高降低是由每个节间长度缩短造成的,与节间数目无关;突变

[研究背景]氮素作为维持甘蔗生长发育的必需大量营养元素之一,在甘蔗的各个不同生长发育时期均起着至关重要的作用.其中氮素利用效率作为甘蔗从土壤中汲取和利用氮素多少差异产生的的主要因素,在很大程度上影响着生产中的氮素投入及消耗总量.研究表明,目前我国多数甘蔗产区存在品种氮素利用率较低、当季氮素投入量过大等问题.因此,培育和发展氮素高效利用品种任务迫在眉睫.就植物氮素利用调控分子机制研究而言,NRT2蛋

塔里木盆地顺北地区碳酸盐岩发育断溶体储层。断溶体纵向深度大、内部非均质性极强,其展布主要受深大走滑断裂带控制。断溶体的储集空间主要为洞穴、孔洞和裂缝。断溶体储层在不同级别断裂带、同一断裂带不同分段内的发育程度有明显差异。如何准确刻画断溶体的空间位置、体积和连通性已成为断溶体油藏勘探开发的主要难点。基于正演模拟和井震结合的储层地震反射特征所分析的断溶体储层地震识别模式,结合结构梯度张量分析、增强相干
