| Abstract: | Variability in incidence of apomictic and sexual embryo sacs was detected in Apluda mutica at Guangzhou City during different seasons in a wild population for two years. Statistical analysis of incidence of apomictic and sexual embryo sacs indicated significant difference in seasons. Frequencies of apomictic embryo sacs were the highest in winter and summer respectively in two years. |
