Effect of hydropriming on germination and location of fungi in Zinnia elegans Jacq. seeds
Summary.

Seven samples of naturally infected zinnia (Zinnia elegans Jacq.) seeds (achene), unprimed and hydroprimed, were studied using germination test performed for disinfected and non-disinfected seeds. Location of inoculum in the seeds was determined by two histopathological methods: mycological analysis of non-disinfected and disinfected seeds and component plating. Priming improved significantly germination capacity at first and second count and decreased the percentage of diseased seedlings and dead seeds. After priming in both non-disinfected and disinfected seeds, increase of the number of seeds infested with Fusarium spp. was recorded. Moreover, total seed infestation increased after the treatment. Before priming fungi infested mainly outer layers of seeds, but inner infection, especially infection of embryo, was higher after priming.

 

Key words: fungi, location of inoculum, hydropriming, seed germination, zinnia seeds
