QAs occurrence and frequency

The QAs occurred in all the legume genera, species and sub-species studied. There were both QAs and QAs plants (Table 28). The frequency of QA occurrence mostly varied (0.1-0.8) between species (P 0.001). The smallest frequency was found in only two species. Trifolium arvense and Trifolium pratense, in which positive test results were not found more frequently than every tenth individual (Table 28). 

The average number of positive individuals clearly doubled for Vida hirsuta during 1999-2001, after which the increase became smaller (Eigure 106).
