The results were as follows: (1) nuclear DNA content of the studied taxa varied from 0.73 pg in diploid R. zhongdianensis (Section Pimpinellifoliae) to 5.07 pg in decaploid R. praelucens (Section Microphyllae), and nuclear DNA content of rose species generally increased with, but not simply proportional to, ploidy level; (2) 1Cx-value varied from 0.37 pg in R. zhongdianensis to 0.89 pg in R. brunonii (Section Synstylae), and the studied taxa were significantly different from each other in 1Cx-value;
