頂端優勢 的英文怎麼說
中文拼音 [dǐngduānyōushì]
頂端優勢
英文
apical dominance-
The absorbing amount of vigorous spikelets was 10 times higher than that of the weak spikelets, especially in hybrid rice combinations
雜交稻及其恢復系在物質分配方面表現出強勢粒對弱勢粒的粒間頂端優勢，雜交組合比相應恢復系的粒間頂端優勢表現更為明顯。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
進一步的實驗發現pf40基因會影響植物側芽發育的早期，即pf40基因作用在側芽形成與發育的早期。對轉基因穀子的組織切片的分析還表明pf40基因引起不同形式的轉基因穀子的維管組織的發育的差異，轉化正義載體穀子的木質部變多，維管系統增多，而反義或干擾的轉基因穀子的木質部數量變少，木質部分化異常。從轉基因的結果可見pf40基因可以減弱植物的頂端優勢，這種作用是通過改變植物體內激素的含量實現的。The cell division element class plant growth regulator is one kind of promotion plant being of ability to promote the vegetable cell fission and the variation, delay the leaf blade senescence, promote lateral bud growth, break the apical dominance, induce injuries of the organization, split up the different organs and promote chloroplast growth and synthesis
細胞分裂素類植物生長調節劑是一種促進型植物激素，能夠促進植物細胞的分裂和變異，延緩葉片衰老；促進側芽發育，打破頂端優勢；誘導愈傷組織，分化成不同器官；促進葉綠體的發育和合成。Committed to improve the competitiveness of retail trade, bringing to its customers : innovation, quality, service and value on a sustainable basis
集中創新、品質、服務和價值的頂端優勢致力於商業企業綜合競爭力的提升。In many plant species, includingarabidopsis, the growth of axillary meristems is inhibited by the primary inflorescence, a phenomenon generally known as apical dominance
在很多植物包括擬南芥中，側芽的生長會被頂端花序的生長抑制，這就是植物特有的頂端優勢現象。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
近年來，分離及研究可以改變側枝生長模式的基因及突變體，經常用來研究這種生命現象，這對于解釋頂端優勢現象是必不可少的。分享友人
