顶端优势 meaning in Chinese
apical dominance
terminal dominance
Examples
- Committed to improve the competitiveness of retail trade , bringing to its customers : innovation , quality , service and value on a sustainable basis
集中创新、品质、服务和价值的顶端优势致力于商业企业综合竞争力的提升。 - The absorbing amount of vigorous spikelets was 10 times higher than that of the weak spikelets , especially in hybrid rice combinations
杂交稻及其恢复系在物质分配方面表现出强势粒对弱势粒的粒间顶端优势，杂交组合比相应恢复系的粒间顶端优势表现更为明显。 - In many plant species , includingarabidopsis , the growth of axillary meristems is inhibited by the primary inflorescence , a phenomenon generally known as apical dominance
在很多植物包括拟南芥中，侧芽的生长会被顶端花序的生长抑制，这就是植物特有的顶端优势现象。 - Recently , the isolation and characterization of genes and mutants with altered shoot branching patterns has been used to study this phenomenon , through the molecular and genetic analysis has been given invaluable information of defective in the branching pattern
近年来，分离及研究可以改变侧枝生长模式的基因及突变体，经常用来研究这种生命现象，这对于解释顶端优势现象是必不可少的。 - Our results provided direct evidence that pf40 gene play a role in the tissue development , with knockout this gene the lateral buds were not visible . the plant hormones auxin and cytokinin appear to play a major role in controlling this process , therefore , the concertrition of auxin and cytokinin was measured , however , the concentration of the two hormone was variation a little in transgenic plants , but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type . furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants , results showed the pf40 could change both xylary fibers and vessel
进一步的实验发现pf40基因会影响植物侧芽发育的早期，即pf40基因作用在侧芽形成与发育的早期。对转基因谷子的组织切片的分析还表明pf40基因引起不同形式的转基因谷子的维管组织的发育的差异，转化正义载体谷子的木质部变多，维管系统增多，而反义或干扰的转基因谷子的木质部数量变少，木质部分化异常。从转基因的结果可见pf40基因可以减弱植物的顶端优势，这种作用是通过改变植物体内激素的含量实现的。
