| 摘 要： | 关于腹毛目纤毛虫棘毛数目的变异已有许多报道，有的种类变异幅度较小，如游仆虫（Ｅｕ－ｐｌｏｔｅｓ）的尾棘毛在２～３根之间变化［１］．有些种类变异的范围和幅度较大，如Ａｍｐｈｉｓｉｅｌｌｉｄａｅｓｐ．［２］．施氏腹柱虫（Ｇ．ｓｔｅｉｎｉｉ）［３］和刺木盾纤虫（Ａｓｐｉｄｉｓｃａａｃｕｌｅａｔａ）［４］．产生这种变异的内在原因 图１ Ｇａｓｔｒｏｓｔｙｌａｓｐ．腹面形态 Ｆｉｇ．１ Ｍｏｒｐｈｏｌｏｇｙ（Ｖｅｎｔｒａｌｖｉｅｗ）ｏｆＧａｓ－ｔｒｏｓｔｙｌａｓｐ．尚不清楚．在刺木盾纤虫上观察到，形态发生…

| Abstract: | Quantitative variation and physiologicalreorganization ofcirriG.sp. are investigated. The results show thatthe variation ofthe num ber and distribution ofcirriis in a large scope. The variation in the num ber ofcirriism ainly due to the quantitative difference of cirrigenerated w hen anlagen break during m orphogenesis. The m orphogenesis of ciliature is sim ilarin both physiologicalreoganization and asexualreproduction. The quantitative variation ofcirrialso occurs during the physiologicalreoganization. |
