Abstract:

Anthurium andraeanum is very famous and precious flower. It is abortion in the northern part of the country, influencing its breeding. The article studies on the process of microsporogenesis and male gametophyte development of Athurium andaeaum, to discuss the cause of abortion and provide the theory evidence for its breeding. By using the general paraffin section technology and the electron microscope technology, the results indicated that the development of anther wall followed the basic type, and the tape of tapetum was the glandular tapetum, 2-cell type pollen. About 90% male gametophyte was abnormal in 2-cell pollen stage. In conclusion the process of microsporogenesis was normal but the deficiency of pollen number led to the maturation.
