珠芽

Leaves usually opposite or alternate, rarely 3-verticillate; leaf axil bulbils absent.

叶通常对生或互生，很少3轮生；叶腋珠芽无。

However, at later stage ToPHAN appeared to be expressed in the boundary of bulbil primordia.

在较晚期的珠芽分生组织，更可以看到ToPHAN 表现在分生组织的边缘。

The bulbil seedlings of Sagittaria wuyiensis prefer low water, this can explain the restrict distribution of its population.

武夷慈姑珠芽幼苗主要定居于0～15cm水深范围之内，这是该植物生长于狭窄生境之中的一个主要生物学原因。

This implied that both genes were involved in bulbiliferous shoot meristem formation while ToPHAN also specified later stages of bulbil formation.

这暗示这些基因可能参与珠芽穗的形成，而ToPHAN 可能与晚期珠芽的形成有关。

ToPHAN and ToSTM seemed to co-opt into bulbil development. Their role thus remains to be explored by promoter analysis and functional analysis in the future.

相较於模式植物阿拉伯芥中，KNOX 基因与ARP 基因拮抗的关系，并没有在俄氏草中发现，它们似乎共同调控了珠芽的形成，需要进一步的功能性分析实验来验证。

Unexpectedly, ToPHAN shared the same expression areas as ToSTM: both were expressed in the center of bulbil meristems but ToPHAN had even a wider expression area.

结果显示ToSTM、ToBP 和ToPHAN均有表现在珠芽分生组织，预期之外的是ToPHAN 在分生组织中心有较大的表现区域。

The part of a historical period is single, be born on stem tuber, petiole grows 8 ～ 25cm, constant purple or green have violet spot, in mid and the following give birth to one bead bud; Form of form of egg of shape of blade long circle, egg of long triangle shape or form of heart shape halberd, grow 20cm of 5 ～, wide 3 ～ 8cm; Tip is long gradually pointed or submit end form sometimes, base form of ministry deep heart, often be above sinuosity have 1 bead shoot, above green, often take below lilac, whole reason, side arteries and veins feather shape, combination is in in close brim.

叶单一，生于块茎上，叶柄长8～25cm，常紫色或绿色具紫斑，在中部以下生一珠芽；叶片长圆状卵形。长三角状卵形或心状戟形，长5 ～20cm，宽3～8cm；先端长渐尖或有时呈尾状，基部深心形，常在弯曲处上面有1珠芽，上面绿色，下面常带淡紫色，全缘，侧脉羽状，在近边缘处联合。

Scape developed. Umbel with many bulblets and few flowers, bulblets leafing on umbel.

花葶发育；伞形花序具很多小珠芽和很少花，小珠芽叶在伞形花序上的。

Scape terminal or lateral, sheathed or naked. Inflorescence a terminal umbel, sometimes with bulblets, rarely flowerless and with bulblets only, enclosed in a spathelike bract before anthesis.

花序顶生伞形花序，有时具小珠芽，很少无花的和仅具小株芽，内藏于佛焰苞状苞片在开花期之前。

There are only two tiny buds on it and the bulbils ?

只有两个小芽上和珠芽

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
