Effects of the Neotyphodium endophyte status on plant performance of Bromus auleticus, a wild native grass from South America

In this work, the hypothesis that endophytes increase plant performance of Bromus auleticus, a native grass from South America was tested. Seed weight, seedling emergence, development, and plant vegetative propagation were compared in plants from uninfected (E-), partially infected (E+/-) or infecte...

Seed weight, seedling emergence, development, and plant vegetative propagation were compared in plants from uninfected (E-), partially infected (E+/-) or infected (E+) seed lots. The hypothesis that endophytes confer resistance to defoliation in one-year-old plants was also tested. Seed lots were collected in different grass populations in the Pampean region in Argentina. E+ lots presented both lighter seeds and lighter and shorter ten-day-old seedlings than E+/- and E- lots. E+ and E+/- lots presented higher percentage and rate of emergence, as well as less time of emergence, than E- seed lots. Plants from E+ lots produced more tillers in a year than E+/- and E- plants. Resistance to defoliation was analysed in plants from one E+ and one E- lot. Infected plants were more resistant to defoliation than E- plants. Our results allowed a preliminary characterisation of this endophyte-plant association. Plants from E+ and E+/- lots presented some advantageous characteristics with regards to seed dispersion, vegetative propagation and resistance to defoliation. © 2006 Balaban. Fil:Iannone, L.J.
