Abstract

Using allozyme analysis, genetic variation of two relict aquatic plants from Primorsky krai, Komarov lotus (Nelumbo komarovii Grossh.) and Gorgon plant (Euryale ferox Salisb.), was examined. The absence of allozyme variation in the Primorye populations of Nelumbo komarovii along with low polymorphism level in the population of Euryale ferox (P 95 = 7.69; A = 1.07; H o = 0.072; H e = 0.038) was demonstrated. Since the data for the species examined are reported for the first time ever, the phenotypes and genetic interpretation of the enzyme systems tested are presented. The isoenzyme profiles of N. komarovii were compared with the data reported for N. nucifera from China. The absence of allozyme variation in N. komarovii, along with extremely low level of variation revealed for E. ferox, is discussed in association with the evolutionary histories of these species, their dispersal after the Pleistocene-Holocene cooling, and survival on this territory in range boundaries.
