哈密瓜在致病菌侵染前后细胞超微结构的变化

Observation on Alteration of Cellar Ultrastructure of Cantaloupe Before and After Infected by Pathogen

摘要:

病原真菌通常会产生侵染垫、附着胞和吸器等侵染结构来完成对寄主的侵染。通过电镜观察不同时间不同病原菌对哈密瓜的侵染状况。试验结果表明,病原菌会导致哈密瓜细胞结构变化,例如细胞壁变薄,叶绿体解体,细胞结构遭到破坏,出现空泡化等一系列发病特征。研究结果为哈密瓜病原菌侵染过程,以及哈密瓜侵染性病害的防治提供了理论依据。

Abstract:

In recent years,more and more studies of concentrated on the plant pathogenic fungi infects plant structure. Pathogenic fungi usually produce infection pad,attached to infect cells and absorbing structures,etc. to complete the host infection process.The infection status of cantaloupe infected by different pathogen at different times was observed throngh electron microscop. The results showed that the incidence of pathogens can cause cantaloupe changes in cell structure,such as cell wall thin,chloroplasts disintegration,destruction of the cell structure,vacuoles and a series of clinical characteristics.The research conclusion will provide theoretical basis for the cantaloupe pathogen infection process,and infectious disease prevention and control,it has a certain reference value.
