Time of harvest determines the postharvest quality of the common mushroom Agaricus bisporus

The effect of harvest time on postharvest quality of mushrooms (Agaricus bisporus strain U1) has been studied. Postharvest quality of mushrooms, especially percentage cap opening, is greater with later harvest times. In addition to time of harvest, the initial size of the mushroom at harvest is significantly correlated with the extent of cap opening.
