The plastid machinery of apical meristematic cells of potato tubers whose growth is regulated by Melaphene

Latent potato tubers of the variety Lugovskoj were treated by the preparation Melaphen (the melamine salt of bis(hydroxymethyl)phosphinic acid) in a concentration of 10E-8 mole during 10 minutes. The control tubers were done by distilled water. The tubers were exposed at dark at 18 deg C during 12-1...

Summary:Latent potato tubers of the variety Lugovskoj were treated by the preparation Melaphen (the melamine salt of bis(hydroxymethyl)phosphinic acid) in a concentration of 10E-8 mole during 10 minutes. The control tubers were done by distilled water. The tubers were exposed at dark at 18 deg C during 12-14 days. Cell ultrastructure of apical meristems and the one of central meristem lower layer was explored. Plastid apparatus area increased under melaphen effect. The total area increased from 4.69 to 6.58 micro square m and the medium area of a plastid did from 2.49 to 3.95 micro square m. A number of plastids containing starch granules increased and a number of the ones with protein inclusions and plastoglobules decreased. A number of plastids with well-developed peripherical reticulum rose, but tubular membrane complex development decelerated in the plastid stroma. A number of plastids with division and blastogenesis symptoms was the same in compare with the control meaning. The conclusion was made that metabolite exchange between plastids and cytoplasm intensified under Melaphen effect. The preparation had much in common by its mechanism of action with kinetine, a natural plant hormone.
