apical dominance meaning in English
顶端显性
顶端优势
Examples
- 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。 - It was also observed that the “ inter - grain apical dominance ” in hybrid rice was stronger than its restorer , which might be one of the main reasons for low seed setting in hybrid rice combination
强势粒对弱势粒物质摄取能力的优势，可能是杂交稻籽粒结实率低下的重要原因之一。 - 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
细胞分裂素类植物生长调节剂是一种促进型植物激素，能够促进植物细胞的分裂和变异，延缓叶片衰老；促进侧芽发育，打破顶端优势；诱导愈伤组织，分化成不同器官；促进叶绿体的发育和合成。 - Millet and tobacco were transformed with the thrt ' e plant expression vectors . our observations with transgenic plants showed that the pf40 gene affected the growth of lateral shoots developing in the basipetal pattern early after floral transition . analysisd the transgenic plants showed the pf40 gene can reduced the apical dominance of both millet and tobacco
测量结果表明pf40基因过量表达的转基因谷子生长素的含量降低为对照的0 . 6 0 . 8倍，而细胞分裂素的含量较对照约升高0 . 2 0 . 35倍，生长素与细胞分裂素的比值在转基因植物中改变明显，降低到对照的一半。
