The sorption surface of roots, as related to the fibrillar structure of cell walls

  • Maria Ryłko
Article

Abstract

The root surface determined microscopically amounts only to ten per cent of the surface assayed with methylene blue. This difference is assumed to correspond to the sorption surface of cell wall interfibrillar capillaries. The volume of these capillaries amounts to 0.1 per cent of the total volume of the organ only, but their surface far exceeds the external root surface. It is suggested that the interfibrillar capillaries of the epidermis cell walls constitute the main elements of the root sorption surface.

Vztah mezi sorpěním povrehem kořenů a fibrilární strukturou blan buněčných

Abstract

Povrch kořenů měřený mikroskopicky tvoří jen 10% hodnoty odhadnuté podle adsorpce methylenové modři. Lze předpokládat, že tento rozdíl odpovídá sorpčnímu povrchu mezifibrilárních kapilár v blanách buněčných. Objem těchto kapilár tvoří jen 0,1% celkového objemu daného orgánu, ale jejich povrch mnohokrát převyšuje vnější povrch kořenů. Mezifibrilární kapiláry v blanách epidermálních buněk by mohly tvořit hlavní složku sorpčního povrchu kořenů.
