Softening Paraffin-Embedded Plant Tissues

Abstract
Soaking paraffin-embedded plant specimens 2–3 days at 37°C. in a mixture of glycerol, 10 ml., Dreft, 1 g., and water 90 ml. is an effective means of softening them prior to sectioning. One side of the paraffin block must be pared away to expose the tissue before immersion in the softening solution.
