Summary

There are numerous instances in which induced plant resistance responses (IR) have
been demonstrated. However, before IR can be made use of in practice it is important
to understand as much as possible the ecology and genetics of the inducing agents
and their interactions with plants and pathogens. Effects of host genetic background
were tested with thirteen tomato varieties and two isolates of Phytophthora infestans.
Isolate effects on inducibility were tested with six varieties and six pathogen isolates.
Leaf disks of plants that had been treated with BABA (DL-3-aminobutyric acid) or
water were inoculated seven days later with 20 µl sporangial solutions of 5*104
sporangia ml-1. All experiments were repeated three times with six replications each.
Disease reductions due to induction ranged from 43 to 100% and were independent of
the susceptibility of the variety to the isolates when not induced. The interactions
between isolate and variety with respect to inducibility were highly significant.
