The extensive variation in chromosome number in root tip cells of three Chinese cabbage-cabbage monosomic alien addition lines with 21 chromosomes, 6-2-4, c-2-4 and d6, was obsevered after vegetative propagation multi-generations. The chromosome number varied from 17 to more than 50. The 25S rDNA signals were very complex in the three different clones.

The characteristic in liquid culture of the purified strains were described, and the relation between the characteristic and the taxonomic traits was researched for the first time. The two groups of Myxobacteria differentiated according to the shape character of the myxospores and vegetative cells had different characteristic in liquid culture.

对纯化菌株的液体培养特征进行了描述，并首次依据初步分类鉴定结果探索了液体特征与分类地位之间的关系，即依据营养细胞和粘孢子形态将粘细菌划分成的两大类型中，第一类型(包括粘球菌属等7个属)的菌株在液体培养基中通常形成片状或絮状，而第二类型(包括单囊菌属等5个属)的菌株则主要呈现球形。

The myxobacteria have a life cycle that is dominated by social behavior. During vegetative growth, cells prey on other bacteria in large groups by gliding motility. When faced with starvation, cells form a macroscopic fruiting body containing thousands of resting myxospores.

粘细菌运动、发育相关基因的克隆及分析粘细菌以具有复杂的多细胞社会学行为著称，它们能够在营养丰富的条件下在固体表面上滑行运动；又能在饥饿的条件下聚集形成子实体结构以及抗逆性的粘孢子。

From 94 soil samples and 9 bark samples in these areas, 259 Myxobacteria strains were isolated and 140 strains of them were purified. These 259 Myxobacteria strains were primarily identified in genus or species level by their fruiting bodies, myxospores and vegetative cells on the base of Sergey's manual of determinative bacteriology and they belonged to 9 genera(Myxococcus, Corallococcm. Angiococcus. Archangium, Cystobacter. Stigmatella . Hapoangium. Nannocystis. Polyangium) of Myxococcales.

根据菌株的特征性子实体形态和其营养细胞、粘孢子形态，以《Bergey's manualof determinative bacteriology》第九版为依据，将分离纯化出的菌株初步鉴定到属，这259株粘细菌菌株经过初步的分类鉴定，分属于9个属，即粘球菌属139株、珊瑚球菌属20株、囊球菌属18株、原囊菌属21株、孢囊杆菌属5株、标桩菌属36株、单囊菌属9株、小囊菌属3株，和多囊菌属8株。

Three terms are used for the soul: nephesh, nuah, and neshamah; the first was taken to refer to the animal and vegetative nature, the second to the ethical principle, the third to the purely spiritual intelligence.

三种形式是用於灵魂： nephesh ， nuah ，并neshamah ；第一次被带到提及的动物和植物的性质，第二的道德原则，第三次的纯粹精神情报。

The characters of regeneration niche for seed germination,seedling growth,soil seed bank and vegetative reproductionof Papilionaceae and Car agana spp.andits relationship withrestoration of desert vegetation were summarized,for the purpose of providing theoretical basis for regeneration niche in the study onreproductive biology and restoration ecology of C.spp..

对蝶形花科，锦鸡儿属落叶灌木柠条(Caragana spp。)的种子萌发、幼苗生长、土壤种子库和营养繁殖等更新生态位特征及其与荒漠植被恢复的关系进行了综述，旨在为柠条的繁殖生物学和恢复生态学研究提供更新生态位方面的理论依据。

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。

The use of the web to spread fears that flicking the switch on the LHC could create a Black Hole that could swallow up the Earth particularly concerned him, he said.

他说，使用互联网散布恐慌说启动LHC会生成一个可能吞噬地球的黑洞的做法让他感到忧虑。

Not a single word have I written down.

我一个字也没有写下来。
