And there are 32 C-bands With which the chromosomes and chromosomal arms can be identified individually·The N-banding pattern:2n=14=2CI+2CI+2CI+2CI+2CI+2CI+S+2CIS· There are rather big differences between the C-band and the N-band.
N 带带型公式为2n=2x=14=2CI+2CI+2CI+2CI+2CT+2CI+S+2CIS. C 带与 N 带有较大的差异.
The varieties with common basic N-nanding pattern (1A, 2A, 3A, 4A, 5A, 6A, 7A) accounted for 11. 96% of studied barleys, the relation-ships between N-banding pattern and geographical region were discussed.
A chromosome banding pattern image analysis software system CHBAN. HUK has ho developed in the light of the theory of image analySis and texutre recogniton and was applied to automated analysis of chromosome N-banding pattern and ideogram of bang wild barley (Hordeum agriocrithon aberg var. nigrum) Moroover, CHBAN. HUK softWare system can rapidly get reliable and accurate chromosome banding pattern and idcograph through computer.
应用图象自动分析和纹理识别的原理,建立了染色体带型自动分析软件系统(CHBAN.HUK),对西藏野生黑稃大麦(Hordeum agriocrithon Aber Var.nigrum)N带带型进行了计算机自动分析,准确、快速地获得染色体的带型图和带型模式图。
The present paper is dealing with the investigation of the chromosome N-banding technique and the N-banding patterns in Hordeum vulgare,Triticum aestivum,Secale cereale,Vicia faba and Allium cepa.
The present paper is dealing with the investigation of the chromosome N-banding technique and the N-banding patterns in Hordeum vulgare,Triticum aestivum,Secale cereale,Vicia faba and Allium cepa.Two N-banding techniques were applied.First, the chromosome slides were stained with Giemsa solution.Second,the slides were treated in 1M NaH_2PO_4 solution at 92-94℃ for 3.5-8.5 min.After rinsing in tap water they were stained with Giemsa solution.The experiments have demonstrated that the N-banding technique is s...
本文研究了大麦、小麦、黑麦、蚕豆、洋葱等染色体的 N 带带型鉴定技术。采用了两种 N 带技术:第一,将染色体标本在5%三氯醋酸(90℃,6分钟)-0.1NHCI(60℃,6分钟)处理,Giemsa染色;第二,染色体标本经 IM NaH_2PO_4(92—94℃,3.5—8.5分钟)处理,Giemsa 染色。试验证明 N 带技术简单、快速,带型清晰。带型分析表明,N 带并非专一地显示核仁组织者。将上述植物的 N 带与 C 带比较,在有些植物中虽然有些 N 带区与 C 带区一致,但也有些区域仅显示出 N 带而无 C 带或仅显示 C 带而无 N 带。为此,N 带技术与 C 带技术的结合使用,将对染色体鉴别十分有价值。N 带同 C 带一样也是细胞遗传学中一个有用的标记。
The present paper deals with the investigation of chromosome N-banding pattern in rice. It was found that all the 12 pairs chromosomes of cultivated rice possessed prominent banding, which shows a form of point.N-bands were mainly distributed near centromere in rice. In addition, interstitial bands, near terminal bands and terminal bands were also observed. Our results obtained showed that the form and position of N-bands of rice chromosome was different from common wheat, barley, Aegilops speltoids, maize ...
The article covers Giemsa C-and N-band types.The C-banding pattern:2n=14=2CIT+2CIT +2CIT+2CIT+2CI+T+2CI+TS+2CITS.And there are 32 C-bands With which the chromosomes and chromosomal arms can be identified individually·The N-banding pattern:2n=14=2CI+2CI+2CI+2CI+2CI+2CI+S+2CIS· There are rather big differences between the C-band and the N-band.Scattered chromocentres can be observed in the in- terphase nuclei treated with the C-banding or N-banding procedure.
本文报道了栽培大麦早熟3号的 Giemsa C 带与 Giemsa N 带带型.C 带带型公式为2n=2x=14=2CIT+2CIT+2CIT+2CIT+2CI+T+2CI+TS+2CITS,共显32条带,可识别每一染色体及染色体臂;N 带带型公式为2n=2x=14=2CI+2CI+2CI+2CI+2CT+2CI+S+2CIS.C 带与 N 带有较大的差异.经过 C 带或 N 带分带处理的间期细胞核内有明显的、分散分布的染色中心,经改造的 C 带分带程序能使较多的带显示出来,具有重复性和成功率较高的优点。
