TAILIEUCHUNG - The cytogenetic effects of sodium metabisulfite, a food preservative in root tip cells of Allium cepa L.

The effects of sodium metabisulfite (SMB) on mitosis were investigated in Allium cepa L. The roots of A. cepa were treated with SMB concentrations of mg/lt, 15 mg/lt and 30 mg/lt for 10- and 20-hour treatment periods. SMB significantly decreased the mitotic index (MI) at all concentrations and treatment periods. | Turk J Biol 25 (2001) 361-370 © TÜB‹TAK The Cytogenetic Effects of Sodium Metabisulfite, a Food Preservative in Root Tip Cells of Allium cepa L.

The roots of A. cepa were treated with SMB concentrations of mg/lt, 15 mg/lt and 30 mg/lt for 10- and 20-hour treatment periods. SMB significantly decreased the mitotic index (MI) at all concentrations and treatment periods. While the decreasing of the MI was dose-dependent at 10 hours treatment time, SMB increased the mitotic abnormalities dose dependently.

A. cepa kökleri mg/lt, 15 mg/lt ve 30 mg/lt konsantrasyonlar›ndaki SMB ile 10 ve 20 saat muamele edilmifltir. SMB, bütün konsantrasyon ve muamele sürelerinde mitotik indeks’i (MI) kontrola nazaran önemli derecede düflürmüfltür. SMB, 10 saatlik muamele süresinde MI’i doza ba¤l› olarak azalt›rken, mitotik anormallikleri doza ba¤l› olarak artt›rm›flt›r.
