Centromeres could be identified easily on the bivalents at diplotene, so it was convenient to analyse the karyotype.
结果表明，日本沼虾染色体数n=52，2n=104，据双线期二价体的相对长度、着丝点位置以及形态诸方面的特点分析了核型，共分为A，B，C，D4个染色体组，核型组成是N=37M+4ST+11T；初级精母细胞减数分裂前期I可分为细线期/偶线期、粗线期、双线期和终变期5个时期，双线期的二价体存在弥散阶段，核仁明显，且双线期二价体着丝点清晰，给核型分析带来了方便。

The results as follows: Chromosomal axial cores formed during leptotene nuclei in spermatocytes of the brown rat, some homologous axial cores were close to each other. The fomation of SCs starts at zygotene, completed at pachytene and disintegrates at diplotene.
在褐家鼠精母细胞的细线期，常染色体轴心（Axial cores， ACs ）已形成，同源轴心在空间上靠近，偶线期SCs 开始形成，到粗线期SCs 完全形成，于双线期SCs 开始解体。

During zygotene on unpaired ACs and lateral elements and central elements of SCs, there are dense spherical or elliptical nodules-zygotene nodules. They play an important part in the process of homologue pairing.
在偶线期未配对的ACs 和SCs 侧生组分及中央组分上均发现电子密度高的球形或椭圆形的节状结构――偶线期节，ZNs 在同源染色体配对过程中起很重要的作用。

All-line phase is also called zygotene.
合线期又称偶线期。
-
At zygotene,t he SC formation initiated at multiple sites in each bivalent but the regions nea r telomeres were preferred.SCs were shortened with development of SCs.Initiation of new SC and extension of existing SC occured simultaneously,and pairing in di fferent bivalents of a nucleus was not synchronised.
结果表明，小麦SC以多点式起始方式于偶线期开始形成；随SC的发育，新的SC形成和已有SC片断的延伸并存；此外，在同一核内不同二价体之间，染色体配对和SC形成并不同步；SC成熟于粗线期，而以破碎方式解体，消失于双线期。
-
At interphase, there is no cytoplasmic channel in the cell walls of PMCs; At zygonema and pachynema, a lot of cytoplasmic channel, ranging in diameter from 150nm to 600nm, appears; After pachynema, the number of channels decrease rapidly.

leptotene：细线期
(1)细线期(leptotene)细胞核内出现细长、线状的染色体,细胞核和核仁继续增大. 在一些植物中,细长的染色体还经过一度缠绕、缩短变粗,使轮廓清晰可见. 这时,每条染色体含有二条染色单体,它们仅在着丝点处相连接. (2)偶线期(zygotene)也称合线期.
-
zygotene：偶线期
(2)偶线期(zygotene)也称合线期. 细胞内的同源染色体(即来自父本和母本的二条相似形态的染色体)两两成对平列靠拢,这一现象也称联会(synapsis). 如果原来细胞中有20条染色体,这时候便配成10对. 每一对含4条染色单体,构成一个单位,

zygotene stage：偶线期
偶线期(zygotene stage)减数分裂前期Ⅰ的第二个时期,此期染色质进一步凝集,同源染色体(homologous chromosomes)发生配对,称为联会(synapsis),所以此期又称配对期(pairing stage).
