The quantities of forest gaps ' age structure are most of prometaphase and after-metaphase , which respectively account for the total number of forest gaps 42.31 % and 38.46 % .

林隙的年龄结构是中前期和中后期数量较多，分别占到林隙总数的42.31%和38.46%。

Clear G bands were obtained in the prometaphase and metaphases of mitotic chromosomes in rye ( secale cereale ) by means of the advanced ASG method .

用改良ASG法在黑麦（Secalecereale）有丝分裂早中期、中期对染色体进行了G-带分析，并作了G-带带型和变动性分析。

The total number of G-bands was reduced by 36 percent , the absolute length of chromosome complement was contracted with 25 percent when cell mitosis proceeded from prometaphase to metaphase .

有丝分裂早中期至中期两个不同时期G－带带纹总数减少36%，染色体组的绝对长度缩短25%，带数减少的幅度大于染色体长度缩短的幅度。

The G-bands at late prophase , prometaphase and metaphase chromosomes have been induced , and the number of G-bands of a cultivar decreases gradually from late prophase to metaphase .

在有丝分裂的晚前期、早中期和中期的染色体都有这样的带纹，同一品种的带纹数目从有丝分裂晚前期到中期逐渐减少。

Chromosome length of metaphase , and prometaphase including the early to late , three stages were 2.19,2.22, 2.32 and 2.29 , respectively . It was obvious that the band number per ju chromosome length of different stages had little difference .

早中期Ⅰ、Ⅱ、Ⅲ和中期染色体组中每单位绝对长度的带数（带/μm）分别为2.19、2.22、2.32和2.29，差异不大。

The results show that there are around 600 bands in the haploid set of the late prophase and 287 bands in the metaphase chromosomes , while prometaphase and early metaphase chromosomes have intermediate numbers of bands . High resolution idiograms for G-banded prometaphase and metaphase chromosomes are drawn .

结果表明，晚前期染色体的带数大约有600条带，中中期有287条带，而前中期和早中期染色体的带数则介于上两者之间。
