摘　　要：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.Quantitative variation and physiologicalreorganization ofcirriG.sp. are investigated.
