| 摘 要： | 以中国对虾原肠期胚胎为材料，采用整体低渗法和管渗法均制备了染色体。通过比较发现，管渗法制备的染色体比整体低渗法的形态好。本文对制备中国对虾染色体技术方面的问题进行了探讨。通过作者的观察，了解到中国对虾染色体徐正常特征外，还存在较特别的形态特征，如主缢痕增强，次缢痕变化，同源配对等。并对产生这些形态特征的原因进行了解释。

| Abstract: | The chromosome of the P. chinests had been prepared with embryo low-osmosis method and cell lowosmosis method using embryo of archenteron stage. The comparison of the two method declared that the morphea of the chromosome using cell low-osmosis was better than that of using embryo low-osmosis method. The technique of the chromosome preparation of P. chinests had be studied. The observation indicated that the chromosome of the P. chinests had some special morphological such as the enhancement of the primary constriction, the variation of the secondary constriction and autosyndetic pairing. The reason which cause these morphological characters were also be interpreted. |
