Abstract
Fresh or pretreated root tips are simultaneously fixed and hydrolysed in 5 N HC1 for 15 min at room temperature. After washing they are macerated on a slide in a drop of 0.05% toluidine blue made up in McIlvaine citric acid-Na2HPO, buffer at pH 4.0. Pressure on the cover slip completes the squash preparation. It is made permanent by removing the cover slip on dry ice, air drying and mounting in Euparal.
