The role of glycosidases activity in the regulation of pollen tube extension in Amaryllis vittata during in vitro germination was investigated. No significant change in the enzyme activities (α-glucosidase, α-galactosidase, rβ-glucosidase and rβ-galactosidase) at different stages of tube growth was found. No increase in patent rβ-glucosidase activity assayed directly in a suspension of intact germinating pollen was observed. The results are discussed in the light of the differential role of wall-bound glycosidases in cells showing overall surface growth and tip growth I.e., pollen tubes. © 1981 Oxford University Press.
