Dear Fello!

There are already many answer added and I donot have time to read all these. You can follow some of the prevention measure to control callus

1. Strict temperature control of incubation room

2. Increase light intensisty it should be more than 70 micro mol per meter sq per sec

3. Incorporate silver nitrate into medium

4. Auxin concentration in the medium should be low and you may also try putriscine

Hope these steps will help you

Regards
