Fruiting Environment

Pause and recall

Check your understanding

Choose your answer before opening the explanation. This is a learning exercise, not a competency assessment.

DMR says Pleurotus need an RH during fruiting of:

  1. 75-85 per cent
  2. 40-50 per cent
  3. 95-100 per cent
  4. About 60 per cent
See the answer and why

75-85 per cent Higher RH with still air invites bacterial spotting.
