Abstract:

Crossing bags manufactured from three grades of polyester and three types of paper bags were tested for their permeability to grass pollen.

Bags were placed on L.perenne plants of known PGI isozyme genotype.

Any pollen passing through the crossing bag and pollinating the plant was detected by assaying its progeny for PGI isozymes. The results obtained allowed differentiation of the various materials for their suitability for pollen proofing.
