The primary result reveals that the normal expression of Clone C103 is profoundly regulated by endogenous auxin in maize root tip, and the expression of Clone C103 maybe has some relationship with statolith in the periphery of central cap.

由此表明玉米根尖内源生长素影响根冠特定基因Clone C103的正常表达；Clone C103在根冠的表达位置推测该基因正常表达可能与中心根冠外周的平衡石有关。

STRUCTURE: Titanium and composites used extensively, with particular emphasis on corrosion resistance; fully articulated three-blade coaxial contrarotatmg rotors have all-composites blades with carbon fibre and glass fibre main spars, pockets (13 per blade) of Kevlar-type material, and filler similar to Nomex; blades have non-symmetrical aerofoil section; each has ground-adjustable tab; each lower blade carries adjustable vibration damper, comprising two dependent weights, on root section, with further vibration dampers in fuselage; tip light on each upper blade; blades fold manually outboard of all control mechanisms, to folded width within track of main landing gear; rotor hub is 50% titaniuin/50% steel; rotor brake standard; all-metal fuselage; composites tailcone; fixed incidence tailplane, elevators, fins and rudders have aluminium alloy structure, composites skins; fins toe inward approximately 25°; fixed leading-edge slat on each fin prevents airflow over fin stalling in crosswinds or at high yaw angles.

结构：钛和复合材料广泛使用，耐腐蚀性能与特别强调，充分阐明三叶片转子同轴contrarotatmg有碳纤维和玻璃纤维的主要棒材全复合材料桨叶，口袋（每刀片13）凯夫拉型材料，类似的Nomex纤维填料；叶片非对称机翼部分，每有地面可调选项卡，每降低叶片振动阻尼器进行调节，包括两部分依赖重根，在机身进一步减振装置；小费每个刀片上轻；刀片倍手动舷外所有控制机制，折叠宽度内的主起落架的轨道；转子中心为50％titaniuin/50％钢；转子制动标准；全金属机身，复合材料tailcone，固定发生机尾，电梯，蛙鞋和方向舵的铝合金结构，复合材料的皮肤；鳍鳍在每个脚趾向内约25 °；固定领先的板式翅片防止了侧风或气流停滞在高偏航角度。

The structure of root tip of sugarbeet and its differentiatienal process of the primary tissue were reported in this paper.

本文报导了甜菜根尖的结构与初生组织分化的过程。

Investigation of DNA replication levels in primed seeds with flow cytometric determination showed that the 6C:3C ratio in embryonic root tip cells was higher than the unprimed seeds at all stages of seed imbibition.

流式细胞分析仪对引发种子DNA复制水平调查结果表明，SMP处理的种子在种子吸胀的各个阶段，胚根尖中6C与3C的比值都高于对照种子。

These results suggested that the stimulation effect of local nitrate on LR growth is dependent on auxin. And the auxin mainly comes from the basipetal transport from shoot to roots, but not from the seed or the basipetal transport of auxin from root tip to LR growth sites.

这些结果表明，局部供应硝酸盐对侧根生长的促进作用依赖于生长素，这些生长素主要来源于地上部生长素向侧根生长部位的直接供应，而不是来源于种子或由根尖向侧根发生部位的生长素向基运输。

The apical bud of Celosia cristata was immersed in 0.05%, 0.1%, 0.15% and 0.2% colchicine solutions for 12 h, 24 h, 36 h, 48 h respectively and the chromosome numbers of the root tip cells in the regenerated plantlets were examined, which showed that the treatment with 0.15% colchicine solution for 36 h would be the best combination that the polyploid rate could reached 23.3%.

采用浸泡法将鸡冠花营养芽在0.05%、0.1%、0.15%和0.2%不同秋水仙溶液浓度下分别处理12h、24h、36h和48h，并对诱导处理后获得的再生植株进行鉴定，得出以0.15%秋水仙素溶液浸泡36h为诱导多倍体的最佳处理组合，诱导率达23.3%。
