| Abstract: | Katahdin and Kennebec potatoes were sprayed with 10?5M auxin at the beginning of flowering. Tubers from the auxin-treated plants were compared with untreated controls for phenolic content, enzymatic discoloration, total nitrogen, nonprotein nitrogen, free ammo acids, lipids, minerals, and ascorbic acid content. In both varieties auxin increased the phenols and enzymatic discoloration. However, no differences were observed in fatty acid composition and ascorbic acid content. Total nitrogen, nonprotein nitrogen, free amino acids, crude lipid, phospholipid and magnesium content were higher, and iron lower, in Katahdin tubers from the treated plants. |
