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
