SUMMARY In the present research, the methods of fluorescent microscopy and histochemistry have revealed the presence of the compounds of primary and secondary metabolism in secretion and cells of the stipu- le colleters in two Galium species, G. album and G. aparine (Rubiaceae). Theobtained data are identi- cal for the both species. It has been shown that proteins, polysaccharides, and lipids, among which the different groups of phenolic compounds, are found in the colleters. Flavonoids are distinguished both in vacuoles of all head cells and in a cell wall; polyphenols and condensed tannins are only in vacuoles. The obtained results allow assuming that the secretion of the glandular hairs carries out various functi- ons: a carbohydrate component provides protection of apex from mechanical damage during growth; it is a nutrient medium for microorganisms; proteins and phenolic compounds act as a chemical barrier against insects and fungi.
