 Alexander's stain is a widely used technique for assessing pollen vitality, but it involves the use of three highly toxic chemicals, chloralhydrate, phenol, and mercuric chloride.

This simplified method is suitable for field studies and allows samples to be collected and fixed on site before being examined under a light microscope.
