A Technique to Facilitate the Paraffin Sectioning of Hard or Brittle Plant Material

Paraffin sectioning of hard or brittle plant material may often be facilitated by reimbibition of the tissue after embedding in paraffin; however, when sectioning seeds, reimbibition may cause the specimen to break out of the paraffin. If the reimbibition is carried out at a temperature just below the melting point of the paraffin) the tissue will not break loose of the paraffin and good sections may easily be obtained.
