Title: Cytologic Studies on the Genus Hemerocallis L.from Kunyu Mountain and its Application
Abstract: The chromosome numbers and karyotypes of two species of Hemerocallis were studied.The results showed that the karyotypes of metaphase chromosomes in somatic cells were as follows:the number of H.citrina was 2n=2X=22=16m+4sm+2T, the AS.K% was 58.9%,the relative length of chromosome was 2n=2X=22=6L+10M1+6S,the total volume of chromosomes was 105.39?um~3.The number of H.esculenta was 2n=2X=22=20m+2T,the AS.K% was 53.8%,the relative length of chromosome was 2n=2X=22=4L+2M2+14M1+2S,the total volume of chromosomes was 99.43um~3.And the morphology of chromosomes was analysed by nested analysis.The result showed there was variation in the degree between individuals and between cells.Moreover the variation in the population was mainly from the variation between individuals.At last application was analyzed.
