How many open flower buds are required to score broccoli for overmaturity?

To determine the overmaturity of broccoli, the scoring is based on the number of open flower buds present on the head. In this case, having four open flower buds is the threshold set by commodity regulations to indicate that the broccoli has reached a stage of overmaturity.

At this point, the physiological changes in the broccoli's flowering structure indicate that the vegetable has started to transition from its optimal harvest stage. It is crucial to monitor these flower buds closely because the presence of open flowers not only impacts the aesthetic quality of the broccoli but also its overall texture and flavor. As such, inspecting the number of open flower buds helps ensure that harvested broccoli meets market standards and consumer expectations.
