中文摘要 | 用顯微鏡檢查苜蓿(alfalfa)花粉與灰黴病菌(Botrytis cinerea)孢子混合培 養五天的材料發現很多受病原菌侵染的花粉粒,所有入侵方式均經由菌絲的尖端 直接入侵,穿透花粉細胞壁,而非經由附著器(appressoria)及入侵坐墊(infection cushions)所造成,通常由花粉的發芽孔入侵比較常見,入侵後菌絲在花粉內增殖 而造成原生質分離細胞質破碎等現象,此一花粉粒帶菌的現象,很可能是造成苜 蓿灰黴病傳播流行的重要因素之一。 |
英文摘要 | A microscopic study proved that pollen grains of alfalfa are susceptible to infection by Botryris cinerea, an important pathogen for blossom blight of alfalfa in western Canada. Pollen grains were inoculated by mixing pollen with drops of a B. cinerea spore suspension on glass slides. Infection occurred by direct hyphal penetration of the pollen cell walls without the formation of appressoria. Infection through the germ pores was observed more frequently than through other parts of the pollen walls. Plasmolysis of the plasma membrane and destruction of the cytoplasm occurred as a result of intensive growth of hyphae in the cell lumen of infected pollen grains. The impact of pollen infection by B. cinerea on the epidemiology of blossom blight of alfalfa is discussed. |
