Fig. 3.

Development of parthenogenetically activated pig diploids cultured in PZM3 or PZM3 supplemented with glucose (PZM3+G) or fructose (PZM3+F) from 4 h to 216 h after electrostimulation. Trials were repeated at least three times in each experimental group, and the total numbers of diploids for analysis were 30, 31 and 33 for those cultured in PZM3, PZM3+G and PZM3+F, respectively. The different small letters (a, b) indicate significant differences in the proportions of diploids that developed to the most advanced stage at each observation point among the experimental groups (P < 0.05). The different capital letters (A, B) indicate significant differences in proportions of diploids that normally developed at each observation period among the experimental groups (P < 0.05).
