The chromosome of somatic cells of 20 four-five year old plants induced by anther culture were examinined and the variation in the chromosome number was studied The results are.1、These Poplar pollen plants are mainly mixoploid;in different plants are not only 1-4n euploid cells, but also aneuploid somatic cells, mainly diploid cells and aneuploid cells;the latter probably arise from multipolar cell division.2、In different individual plants, the pereentage of different euploids and aneuploids are different,...

The chromosome of somatic cells of 20 four-five year old plants induced by anther culture were examinined and the variation in the chromosome number was studied The results are.1、These Poplar pollen plants are mainly mixoploid;in different plants are not only 1-4n euploid cells, but also aneuploid somatic cells, mainly diploid cells and aneuploid cells;the latter probably arise from multipolar cell division.2、In different individual plants, the pereentage of different euploids and aneuploids are different, which directly effect the growth of plants. Those containing mainly diploid cells grow faster;those containing mainly aneuploid cells grow slower.3、During the process of growth ploidy of the chromosome of somatic Cells of pollen plants varies continuously. Haploids may change into diplo;ds, i. e. autoploidy, probably due to intranuclear mitosis and nnclear fusion.

观察了用花药培养方法诱导出来的4—5年生20个当代植株体细胞染色体在数量上的变异,其结果如下: 1、杨树花粉植株基本上为混倍体、即在同一植株内不仅存在1—4倍的正倍体细胞,而且也有介于1—2倍体间的非正倍体细胞,其中以二倍体细胞和介于1—2倍体问的非正倍体细胞占多数。而后者的产生可能与多极有丝分裂有关。 2、不同植株中各种正倍体和非正倍体细胞所占比例不同,且直接影响植株的生长势。就中东杨花粉植株来看,生长快的植株中二倍体细胞占多数,生长慢的植株中介于1—2倍体间的非正倍体细胞占多数。 3、在生长过程中,花粉植株体细胞染色体倍数性在变化,有由单倍向二倍体转变即自然加倍的趋势。核内有丝分裂及核触合等有丝分裂的异常过程可能是其重要原因。

Haploid plants obtained by the in vitro anther culture were plantedin the experimental plot.The anthers were collected from a hybridbetween Populus simonii,P.nigra and P.berolinensis Dippel.After plantingthe number of chromosome of the haploid plant was examined undermicroscope for four times within 8 years.It was revealed that the plantshad gradually changed their tissues into those dominated quantitativelyby diploid cells from chimera dominated by haploid cells. The number of chromosome was doubled at the age of 7—8 yearsand the plants became completely diploid ones.

通过杂种杨(P simonii×P.nigra;P.berolinensis Dippel)花药的离体培养,获得了单倍体植株。这些植株被移栽到试验园地生长,8年中进行了四次染色体检查,发现它们由单倍体细胞占优势的嵌合体植株逐渐变成了二倍体细胞占优势的植株。通过7—8年的生长和发育,自然加倍变成了纯合二倍体。

An observational experiment has been made on the micro-morphology of the anther and pollen of black wattle (Acacia meansii) with the scanning electron microscope.The result indicates that the morphological structure of the anther turns out to be somewhat different from the previous reports. The structure of anther wall, with the exception of tapetum, consists of a series of structural constituents. Each individual anther produces 8 polliniums, while one pollinium is composed of IQ pollen...

An observational experiment has been made on the micro-morphology of the anther and pollen of black wattle (Acacia meansii) with the scanning electron microscope.The result indicates that the morphological structure of the anther turns out to be somewhat different from the previous reports. The structure of anther wall, with the exception of tapetum, consists of a series of structural constituents. Each individual anther produces 8 polliniums, while one pollinium is composed of IQ pollen particles. In addition, the pollinium pattern is in correspondence with the morphological structure of the tapetum.

用扫描电镜对黑荆树花药及花粉微观形态进行观察,其形态结构与以往报道的花药形态结构有差异。绒毡层以外是由结构块交错排列而成;花药纵裂的两侧及两花药片之间的结构块比较规则。每一个花药产生8个花粉复合体,每个复合体由16个花粉粒组成,复合体花粉的纹饰与绒毡层的形态结构吻合。
