The suggested criteria for identifying MN were; (i) rounded smooth perimeter suggestive of a membrane; (ii) less than a third the diameter of the associated nucleus, but large enough to discern shape and colour; (iii) Feulgen positive, i.
The gill tissue was fixed in Carnoy's for 24 h (ethanol-glacial acetic acid, 3:1 v/v) and then stained with the Feulgen reaction (Navarrete et al.
On days two and three, respectively four and two root tips were excised from each bulb and microscopy slides were prepared in accordance with the Feulgen reaction procedure: fixation of the root tips in Carnoy reagent (ethanol 95% and acetic acid 45% , 3:1) for 20 min at room temperature, hydrolysis with 1 N HCl at 60[degrees]C for 7 min.

They appeared round to oval, amphophilic, and hyaline in sections stained with hematoxylin and eosin, and magenta with Feulgen stain.
This peculiar staining and large nucleus size led previous investigators to ask whether these cells were polyploid, but a Feulgen stain established that this was unlikely (Foelix & Troyer 1980).
Root tip squashes were stained with feulgen stain and data was collected for mitotic index and chromosomal aberrations.
