Abstract
This invention provides an immunologic method for measuring plant pollen germination and pollen tube growth. This method is based on the finding that an antibody having specificity to .beta.-L-arabinofuranosyl residues binds to the surface of in vitro grown pollen tubes. Antibody binding can be measured qualitatively or quantitatively using a calibration curve. The immunoassay is useful for screening plants for response to substances that affect plant germination or pollen tube growth.
