Abstract
The study deals with the distribution of non-specific esterase in germinating pollen grains ofPortulaca grandiflora. Intense activity of the enzyme is seen in small granules distributed homogeneously in pollen grains stigma hairs and throughout the length of pollen tubes. Further the walls of pollen grains also demonstrate intense activity. The functional significance of the enzyme in these locales has been discussed. Autor studoval distribuci nespecifických esterás v klíčících pylových zrnech šruchy velkokvěté (Portulaca grandiflora). Vysoká aktivita enzymů byla pozorována v malých granech homogenně rozložených v pylových zrnech, v trichomech blizny a podél pylové láčky. Vysokou aktivitu vykazovaly též stěny pylových zrn.Keywords
