组织培养

The best example of this phenomenon is the formation of adventitious embryos in carrot tissue cultures.

On low-magnification light microscopy, the specimen had a patternless tissue culture-like appearance with increased mitotic actiity, randomly oriented spindle cells, and extraasated red blood cells (Figure 2B ).

低倍光学显微镜下，标本显示无图案的&组织培养样&表现，伴有有丝分裂活性增高、未定性的梭形细胞和红细胞外渗（图2b），组织病理学所见符合结节性筋膜炎。

In this thesis, regenerated plants were obtained from embryonic calli induced from eachof several rice–Zizania introgression lines , their rice parental line as well as F1hybrids between introgression lines and the parental line, by using mature seeds as explants.

本论文通过成熟胚诱导水稻松前和渐渗系以及它们之间杂交种的愈伤组织，并分化出再生苗，研究转座子mPing和反座子Tos17在水稻经组织培养过程后在基因组中的变化特点。

The experimental result shows that the main determinative factor is the temperature of the sea water for the growth after the transplantation; the optimal temperature for the growth of Zostera marina L. is 10~20℃; it is strongly salt-tolerant and it can grow at the salinity range of 20‰~48‰ normally; its rhizome is the optimal organ for culturing and the optimal hormone concentration for the calluses induction is 2mg/L or so.

实验结果表明，大叶藻移植后生长的主要制约因素是海水温度；大叶藻生长的最适温度是10～20℃；大叶藻对盐度的耐受性很强，它可以在盐度为20‰～48‰的范围内正常生长；地下茎是组织培养的最适材料；诱导愈伤组织的最适激素(2，4-D)浓度为2mg/L。

In the study 101 local varieties, 83 modern cultivars, 72 new families of wheat were analysed for the days of callusing at 50%, the number of callusing in 4 weeks in callus induction; and rate of Calli of root formation and the rate of calli of shoot formation in differentiation culture.

为了选育商业应用价值好的新品种，作为受体的植物还需要农艺性状好，育种价值高。一个关键问题是，遗传转化技术是建立在植物的细胞和组织通过组织培养过程再生植株的技术体系上。

The average recoveries of the exogenous hormones were more than 85%.

在组织培养的不同阶段，植物组织对激素的含量和比例要求不一致，甚至差异很大。

The calli from two explants of three genotypes have shownsignificant difference in regeneration.Genotypic variationin culture response was also significant.The maximumregeneration was achieved in Basmati 198 followed by Basmati 370and KS 282 in both explants.

三个基因型的两种不同外植体的愈伤组织表现出显著不同的再生能力，基因型的差异对组织培养的差异也很明显，Basmati 198在继Basmati 370和KS 282的两种外植体之后达到7最大的再生能力。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
