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,但頂芽最后并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。

Ground meristem the central region of the apical meristem from which the ground tissues of pith , cortex , medullary rays , and mesophyll differentiate . in root meristem it is also called periblem 基本分生組織:位于頂端分生組織的中部,髓、皮層、髓射線以及葉肉這些基本組織均是由基本分生組織分化而成。根部分生組織也稱為皮層原。

The results demonstrated that the most rapid growth of the dendrites occurred during the second postnatal week and the apical dendrites more rapidly matured in branching and lengthening than the basal dendrites did 結果表明錐體神經元樹突的生長在生后第二周最快,并且頂樹突的分支和長度均較基樹突快。

Description : perennial herbs , 5 - 20 cm tall , densely white villose ; roots slender , terete , up to 40 cm long , fleshy , stem buried in sand with apical part emerged above ground 形態特徵:多年生草本,高5 - 20厘米,全株密被白色長柔毛;根細長,圓柱形,長達40厘米,肉質;莖大部埋藏于沙中,部分露出地面。

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 強勢粒對弱勢粒物質攝取能力的優勢,可能是雜交稻籽粒結實率低下的重要原因之一。

Older leaves have ivory - tinted necrotic spots and shreaks coalescing into larger scorched areas ; some leaves show pale ( faded ) yellow chlorosis over whole surface of apical regions 缺鉀的大麥葉片:老葉出現灰白色斑點,逐漸連在一起呈燒焦區域,有的葉片黃化一直到葉尖。

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。
