摘要: Nuclear DNA amount of five species ofCelosia ranging from 2x to 12x varies 3.26 (2x) 9.70pg (12x). The diploidC. trigyna has twice as much DNA/basic genome other taxa, which is commensurate with its taxonomic position and genetic isolation. There insignificant variation in among 4x, 8x, taxa. Therefore, DNA/nucleus shows a strong positive correlation ploidy level. different accessions 4x taxa show constancy amounts. no seed weight amount.
