Abstract
The paper deals with the distribution of alpha and beta-glucosidases in the germinating pollen grains ofPortulaca grandiflora. Both these enzymes are localized in the pollen wall and the cytoplasmic granules. The latter are distributed throughout the pollen cytoplasm, pollen tube and stigma hair. In non-germinating pollen grains, enzymes are concentrated in the pollen wall. Stigma hair sheaths are completely free from enzymes. The functional significance of these enzymes in the hydrolysis of phenolic glycosides and polysaccharides is discussed.
