Description
In this study we investigated the efficiency of fungal endophyte (Acremonium loliii) transmission from plant to seed in annual ryegrass (Lolium multiflorum). Results indicated that the endophyte begins to move up or grow up the plant at about growth stage 30 of Zodoks scale, when day temperatures were near 25° C. In our study, we found that the endophyte was not transmitted to all seed for two reasons. Most importantly, the endophyte was not transmitted into some seedheads even though the plant was infected, indicating the tiller was not infected. Secondly in some infected seedheads, a very small number of seed were not infected, indicating that the endophyte was not transmitted into a seed.
