Abstract:We observed the embryonic development of normal diploid (N), gynogenetic diploid (G) and haploid (H) of Nibea albiflora , and its early growth were compared. The results were as follows: (1) Fertilization rate N>H>G, Hatching rate N>G>H, Deformity rate H>G>N, 72 hours survival rate N>G>H. (2) It took about 21 hours 10 minutes for the normal diploid, for gynogenetic diploid and haploid, however, it took 23 hours 10 minutes and 23 hours 30 minutes to hatch, respectively. The embryonic development lag phenomenon were mainly appeared in early gastrula stage and hatching stage for gynogenetic diploid, in late gastrula stage for haploid. Morphologically, the haploid embryos showed typical haploid syndrome, while the gynogenetic diploid and normal diploid embryos had normal morphology and no significant difference between them. The death peak appeared in late gastrula stage for each group, all haploid larvae dead before mouth open period. (3) Before 60 days age, the growth rate of gynogenetic diploid was obviously slower than normal diploid and individual quite different within the former group.
