| 摘 要： | After male sterile rice plants are inoculated with secondary sporidia of Neovossia horrida in the field,the process of infection is comparatively studied in four male sterile rice lines by scanning electmnmi-croscope. The infection process of Neovossia horrida is similar in these four male sterile lines. The results show, that the hyphae of fungus penetrates directly to the stigma, and then to the ovary after inoculation for 8h. The initial teliospore is formed between the aleurone layer and seed coat after 7d and matured in 9d. Although fungus penetrates through stigma without pollination, teliospore occurs only in the healthy developing endosperma. |

| Abstract: | After male sterile rice plants are inoculated with secondary sporidia of Neovossia horrida in the field, the process of infection is comparatively studied in four male sterile rice lines by scanning electronmicroscope. The infection process of Neovossia horrida is similar in these four male sterile lines. The results show, that the hyphae of fungus penetrates directly to the stigma, and then to the ovary after inoculation for 8h. The initial teliospore is formed between the aleurone layer and seed coat after 7d and matured in 9d. Although fungus penetrates through stigma without pollination, teliospore occurs only in the healthy developing endosperma. |
