A commonly used technique for assessing pollen vitality, Alexander¡¯s stain, uses chloral hydrate, phenol and mercuric chloride, all of which are highly toxic. We describe here an improved pollen staining technique that avoids the use of a regulated chemical chloral hydrate and two extremely toxic chemicals mercuric chloride and phenol, and requires a much shorter time period for sample preparation and staining. This simplified method is very useful for field studies without high-end equipments such as fluorescence microscopes. Samples can be collected and fixed in the fields and examined in a simple laboratory that has light microscopes. %K pollen staining %K Alexander¡¯s stain %K chloral hydrate %U http://www.pagepress.org/journals/index.php/pb/article/view/1770
