Using count the leave.and flow cytometric to identifiy ploidy levels for the regenerated plants derived from antherculture in burley tobacco in this article,it shows that using count the chloroplast method could identify the ploidy levels simply and economic but it cannot identify the mixoploid accurately, so it easily lead to misidentify.
本文分别用气孔保卫细胞叶绿体计数和流式细胞仪两种方法来鉴定花药培养再生植株染色体的倍性,结果发现叶绿体计数法可以简单经济的检测烟草花药培养再生植株的染色体倍性,但它不能准确地鉴定出混倍体植株,易造成误判。

In the offsprings of the aneuploids (P3) with 41~44 chromosomes, there are four types of plants with 29~32 chromosomes. Except the plant with 29 chromosomes, others which appeared abnormal meiosis behavior and poor pollen fertility are mixoploid.
在染色体数为44与41的两种超倍体(P3群体)后代,鉴定出具有29~32条染色体的4种非整倍体,除染色体数为29的植株外,其余均为混倍体,它们的减数分裂异常,花粉育性低。

Karyotypic findings showed that all cultivars were mixoploid with chromosome number ranging from 49 to 57, and 54 was the most frequent number observed.
结果表明:(1)17个栽培小菊均为混倍体,染色体数在49~57之间变异,以54条为主;(2)染色体呈现多态性:多数品种由中部、近中部和近端部着丝粒染色体组成;最长与最短染色体的比值为1.62~2.39;臂比>2的染色体所占的比率为11.11%~29.62%;核型不对称系数为59.74%~63.37%;3个地被菊品种和'奥运橙光'、'金陵白凤'(2n=53)核型类型为&2B&,其它品种为&2A&型。

autotetraploid:同源四倍体
二倍体材料经过秋永仙碱处理后,一些材料细胞的染色体全部加倍,成为同源四倍体(autotetraploid);一些材料二倍体与四倍体细胞并存出现嵌合体(cytochimaeras)现象;一些材料二倍体、四倍体细胞以及更高倍性的细胞混合而形成混倍体.

mixoploid:混倍体
指在同一个体中二倍性组织与非二倍性组织混存的现象(B.Nemec,1931),此时称该个体称为混倍体(mixoploid). 这种个体的染色体数仍表现为多倍性的和异倍性的变化. 用秋水仙素处理引起体细胞的染色体数加倍时,二倍性细胞和多倍性细胞也往往混在一起.
