查询词典 vegetative form

The allomatric scaling for the wet clonal plants including Phalaris arundinacea Scirpus planiculmis Phragmites australis and Phragmites Jeholensis did not show "1/4-power Rule". The variation of the allometric exponents between vegetative and reproductive ramets was mainly due to the different regulation mechanisms in different development stages. Moreover, the variation of the allometric exponents between plantsin wet or drought environments was the result of the long-time divergent response for ramets to moisture environments.

虉草、紧穗三棱草、芦苇和热河芦苇4种湿地根茎植物分株异速生长规律并不表现为&1／4或1／4整倍数&规律，营养株和生殖株异速生长幂值的差异是不同发育类型的分株生长调节机制不同的结果，水生生境和旱生生境分株异速生长幂值的差异则是分株对生境水因子差异长期趋异响应的结果。

When pea ( Pisum sativum L.,Alaska strain) was grown in short\|day conditions,the apical bud senescence started with the transformation of the bud from vegetative to reproductive growth.DNA fragmentation was detected during the senescence using the terminal deoxynucleotidyl transferase\|mediated dUTP nick end in situ labeling method.The cell ultrastructural changes were similar to apoptosis in animal cells:the apical meristemetic cells underwent the programmed cell death.This wa...

显微、超微结构研究表明，短日照条件下豌豆顶芽的衰老过程是从营养生长锥向花芽的转化，而用DNA原位末端标记、Caspase 8WesternBlot和 14 0bpDNA片断积累的试验结果证明，转化为花芽的整个生长锥细胞发生了编程性死亡，而且其最顶端部分细胞首先发生PCD ，而顶端周围的分生组织细胞逐渐分化出花芽的各部分，但顶芽最后并没有发育成为完整的花，所有细胞就都发生PCD ，从而顶芽衰老

After different concentration grades of 2,4-D were added into the vegetative green cells respectively, then H. pluvialis were cultivated under unfavorable growth conditions (24 h light cycle, 5000 Lx, 25°C, nutrition deficiency) to promote astaxanthin accumulation.

在对数生长期的藻液中分别加入一系列不同浓度的2，4-D溶液，然后进行胁迫培养(25°C、24 h、5000 Lx连续光照+营养盐饥饿)，诱导细胞内虾青素的合成积累。

Effect of extraneous salicylic acid on astaxanthin accumulation was studied in alga Haeinatoccu pluvialis. After SA was added into the vegetative green cells at a different concentration, the alga was cultivated under unfavorable conditions (24 h light cycle, 5000lx, 25℃, nutrition deficiency) for growth to promote astaxanthin accumulation.

在对数生长期的藻液中分别加入不同质量浓度的水杨酸溶液，进行胁迫培养（25℃，24h 5000 lx连续光照＋营养盐饥饿），诱导细胞内虾青素的合成积累。

Nd:YAG Laser (wavelength 1.06μm, power 30w, 40w)was used to irradiate the vegetative cells of Haematococcus pluvialis, and with irradiate does of 10 sec, 30sec,60sec.

利用Nd：YAG激光(波长 1.06μm，功率30W，40W)照射雨生红球藻的营养细胞，辐照时间为10sec，30sec，60sec。

Vegetative growth ability of Potamogeton malaianus decreased while reproductive ability increased through the whole winter.

4在经过冬季越冬期后马来眼子菜的营养生长能力下降，繁殖能力上升。

In the plant vegetative growth, leaf primordia arise from groups of initial cells within the peripheral zone of the shoot apical meristem.

叶是植物进行光合作用的器官。为了适应自然环境，植物叶在漫长的进化过程中发展成今天这样的千姿百态。

Under light, middle and heavy degradation, with the increase of degradation, the vegetative ramet capacity of the clones increased, while their reproductive ramet capacity decreased. A typical landscape of "black soil beach" appeared in grassland with extreme degradation; the growth of the clones was in a lowest level.

在轻度、中度和重度退化程度下，随着退化程度的增加，高山嵩草无性系营养分株能力加强，生殖分株能力减弱；极度退化的草地已呈现典型的&黑土滩&景观，高山嵩草的克隆生长维持在最低水平。

Taking the guerrilla type clonal plant Kingdonia uniflora at different altitudes in Taibai Mountain National Forest Park of Shaanxi Province, China as test material, the C, N, P, K and Mg contents in different vegetative organs of its ramet were measured.

以分布在太白山国家森林公园3个海拔高度的游击型克隆植物独叶草为研究对象，分析测定了不同分株营养器官中C、N、P、K和Mg含量。
