Seed Characteristics and Germination of Celosia cristata of Forth Space Mutagenesis
In order to provide references for germplasm improvement and variety selection of Celosia cristata, seeds without mutagenesis of C. cristata (CK) and three seeds with space mutagenesis (H1, H2 and H3) were used as experimental materials to compare seed characteristics and germination status. Results showed that there were differences in 1000-grain weights, germination potentials, germination rates and protein contents among seeds of H1, H2 and H3 mutant species. H1 mutant species performed better, with 1000-grain weight, germina-tion potential, germination rate and protein content of seeds significantly higher than those of CK, which were 1.28, 1.20, 1.13 and 1.14 times higher than those of CK respectively. There were differences in germination sta-tus among seeds of H1, H2 and H3 mutant species. H1 mutant species showed the best performance. Fresh weight of cotyledon, hypocotyl length, radicle length and SOD activity of seeds were 1.29, 1.45, 1.33 and 1.31 times higher than those of CK respectively. Followed by H2 mutant species, with all other indexes, except for 1000-grain weight and protein content of seeds significantly higher than those of CK. Indexes of H3 mutant species were better than those of CK, xcept for 1000-grain weight and radicle length of seeds, other indexes had no dif-ferences with CK. Space mutagenesis produced favourable variations in C. cristata seeds.
