SONGÜL ÇANAKCI-GÜLENGÜL
Abstract
In this study, SNPs (0, 50, 100, 200 and 300 μM) were applied to the 10-day-old seedlings of Raphanus sativus L. (cherry bella) by radical hydrophonic method for 5 days and various biochemical effects of SNP on seedlings were investigated. Compared to the control, theleaves were shown tothe loss of pigment (kl (a+b) and carotenoid), soluble protein and amount of MDA, GSH and GSSG decreased. In addition, the activity of SOD decreased while, the activity of CAT increased. Extraordinary increases and increases in stearic and linolenic acid were observed, with % rations of fatty acids in the leaves showing a decrease and an exceptional reduction in palmitic, linoleic and palmitoleic acid. In general, high doses of SNP triggered toxic effects. Keywords: Raphanus sativus L. (cherry bella), sodium nitroprusside, NO, toxic stress.
