摘要盆栽3年生愛文檬果枝條于花期去頂后，葉腋側芽可分化成正常的花序、混合花序與新梢等三種類型。Flower buds trees can be produced terminally.
樹木的花芽，可能是頂生的。Some cultivars also form fruit buds on the tips of the current season's vegetative shoots.
一些栽培品種也在當年的生長枝的頂端形成花芽。The terminal bud continues vegetative activity during most of the growing season.
在大部分生長季節，這種莖的頂芽繼續著植物的生長。Effects of removal of the shoot apex and leaf wounding on nitrogen uptake and nicotine production were studied with tobacco plants grown in sand or hydroponic medium under the controlled conditions
摘要採用砂培和營養液培養方法，研究了在營養生長階段切除頂芽和葉片損傷對煙株生長、體內煙堿濃度、氮濃度及吸氮量的影響。Tufted perennial with strong creeping stolons ; leaf yellowish green to green, folded in bud ; leaf blade smooth, lanceolate, slightly bent at the joint with the sheath ; inflorescence of a terminal single raceme, spike - like, smooth, sub - sylindrical and slightly bent inwards
本種為多年生，簇生性，具強壯匍匐莖；葉綠至黃綠色，在芽期褶生，葉片多平滑，披針至長條形，先端略鈍，于葉鞘成一角度折生；花序為單一頂生總狀花序，光滑無毛，平扁，稍向內彎。Also unlike auxin, cytokinins promote the growth of lateral buds, not shoot tips
同樣不同於生長激素，細胞分裂素促進側芽的生長，而不是頂芽的生長。The outcome shows that naixiong crude drugs is little iightcoioured, has a protruding terminal bud, has little fragrance ; the bodily form of shanchuanxiong is emacicated and small sized, has a dry and decayed gully in the middle part, has a strong fragrance the wooden degreen of naixiong " s fibre is at a lower stage, and thas small oil drops ; but chuanxiong and shanchuanxiong ' s are at a higher stage, and they has oil drops in abundance
對奶芎、山川芎與川芎進行了生藥學研究：奶芎藥材顏色較淺，頂端有一突起的頂芽，氣微香；而山川芎體形枯瘦，個體較小，中心常有枯朽狀溝槽，氣香。奶芎組織中纖維木化程度低，油滴較少；而川芎、山川芎纖維木化程度高，油滴較多。Labeling tunel method. the cell ultrastructural changes were similar to apoptosis in animal cells : the apical meristemetic cells underwent the programmed cell death. this was first detected in the apex cells of apical meristem, while peripheral cells differentiated gradually into different parts of a floral bud. but all the cells in the floral bud were subjected to the pcd process before it developed into a complete flower. 140bp dna fragment was found to deposit in apical bud during the plant development. the most important role of caspase - 8 was detected by western blot, and the expression of the procaspase - 8 was time - related with the dna frgmentation and the transformation from vegetative to the reproductive growth. these results suggested that pcd was an active process during the differentiation of apical meristem, and the senescence observed in the apical bud was due to the pcd process
顯微超微結構研究表明，短日照條件下豌豆頂芽的衰老過程是從營養生長錐向花芽的轉化，而用dna原位末端標記tunel caspase - 8 western blot和140 bp dna片斷積累的試驗結果證明，轉化為花芽的整個生長錐細胞發生了編程性死亡pcd ，而且其最頂端部分細胞首先發生pcd ，而頂端周圍的分生組織細胞逐漸分化出花芽的各部分，但頂芽最後並沒有發育成為完整的花，所有細胞就都發生pcd ，從而頂芽衰老。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。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。Primary growth growth derived solely from meristems present in the embryo, i. e. apical meristems
初生生長：指完全起源於胚芽分生組織即頂端分生組織的生長。Often multi - crowned. may develop sideways growth habit. semiminiature to standard
通常多個頂芽。有時候會有歪向一邊生長的習性。半迷你到標準型。Removal of the shoot apex and leaf wounding did not show any influences on nitrogen uptake by plant, but increased nicotine production per unit nitrogen
切除頂芽和葉面損傷對煙株體內的氮濃度及吸氮量均無顯著影響，但顯著提高了煙株體內單位氮素產生煙堿的能力。分享友人
