Plastic tissue culture box  Magenta box is an autoclavable polycarbonate/polypropylene box used often in plant tissue culture.  An alternative to the plastic box is a glass baby food jar with a polypropylene cap.  Our technicians use either container, but use the term 'magenta box' to describe both in their protocols. Baby food jar with polypropylene cap. 

Rice seeds should be dehulled by hand instead of mechanical means in order to preserve the embryo.  Click here to see tools that our technicians use to quickly dehull seeds for this procedure.
