Extracts of the intact stigmatic surface of 10 species from different families contained little or no free sugar. The principal components of the extracts consisted of phenolic (anthocyanins, flavonoids, cinnamic acids) and lipid compounds. The phenolic compounds occurred as glycosides or esters. Phenolic compounds could inhibit insects and diseases, stimulate or inhibit pollen germination, or provide specificity to the pollen selection‐germination process of the stigma by interacting with growth‐regulators or related compounds.
