Table 3.

Sensitivity of dormancy onset to variation in RH under field conditions. Each row represents samples exposed during the specified dates; columns 2–5 are the duration of exposure (h) below the RH threshold specified, column 6 is the minimum humidity experienced during exposure and column 7 is the level of dormancy measured following exposure. The control sample was maintained at 75 % RH throughout the experiment and tested upon conclusion
