Abstract:
Two cytotypes of Scilla indica and three other species, namely S. nervosa, S. siberica and S. vindobonensis were investigated. The estimation of nuclear DNA content was utilized as a measure of genetic diversity at inter- and intraspecific levels and as an index of the trends of evolution. S. siberica with a very high DNA value was regarded as indicative of a primitive state. The heavy intraspecific difference in DNA content in S. indica has been attributed to amplification of the DNA.
