During the UV-A radiation period from 5 min to 60 min, the spore viability significantly
decreased (F1,56= 55.0;P< 0.001), significantly differed between
the treatments (F3,56= 330.5;P< 0.001) and a significant interaction (F3,56= 4.3;P< 0.01) indicated a weaker decrease of viability in the water-spore suspension
