查询词典 meristematic

When the seeds sprout, some individuals produce annularly inflated hair zones above early initial roots near root tip meristematic zones.

Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.

结果显示：接种后6 d的根尖分生区、伸长区出现膨大、对称的根结，根中心的原形成层细胞分化出巨型细胞；10 d在根毛区及以上部位出现既有对称又有偏于一侧的根结，周围有原生木质部导管出现，根结中巨型细胞阻断了导管；16 d次生维管组织提早出现；20~30 d导管纵向排列无序，形状扭曲，皮层中有新维管组织产生。

Tillering in rice is one of important agronomic trait that determine grain yield. Tillering is also of developmental importance because tiller is special type of branches which is quite different from that of dicot plants. M0C1 gene can control formation of axillary meristematic tissues and tillering bud in rice, and its subsequent outgrowth.

分蘖是水稻等禾谷类作物最重要的农艺性状之一，它直接决定着水稻穗数的多少并进而影响水稻单位面积的产量；分蘖又是单子叶植物一种特殊的分枝现象，具有重要的发育生物学意义。

It is formed when parenchyma cells resume meristematic activity.

它由恢复分裂能力的薄壁细胞组成。

During secondary growth,the meristematic PHELLOGEN gives rise to parenchyma tissue,the periderm, which forms the secondary cortex.

在次生生长过程中，周皮分生组织的分裂活动所产生薄壁组织细胞，形成栓内层。

PXY is expressed within dividing meristematic cells of the procambium, whereas CLE41 localises to the adjacent phloem cells.

PXY在分裂中的原形成层分生细胞中表达，而CLE41定位于毗连的韧皮部细胞。

Further examinations of cell size, trichome distribution and meristematic activity failed to find any differences between cotyledons of European species. All observations showed that both cotyledons of European Gesneriaceae species ceased to grow in early stages and thus no prolonged meristematic activity could be observed.

进一步检测子叶的细胞大小、毛状物的分布、及分生组织活性检测均显示欧洲苦苣苔科成员的两片子叶在发育早期已停止生长，两片子叶间也无形态上明显的差异，同时也无法观察到持续的分生组织活性刺激子叶持续生长。

During vascular development, the meristematic cambial cells divide down their long axis in a highly orientated manner to generate clear files of cells.

在维管束的发育中，形成层细胞高度方向性地以分割长轴的方式分生产生明显的细胞队列。

The role of NAA in the formation of root primordium is the induction of cortical cells to differentiate meristematic cells which possess meristematic ability.
