Effect of boron on enzymatic discoloration and phenolic and ascorbic acid contents of potatoes
Boron (B)-treated and untreated Ontario potatoes were compared for enzymatic discoloration and phenolic and ascorbic acid concentration. The source of B was borax (Na2B4O7.10H2O) Which was sprayed on the leaves at the rate of 3.36 kg/ha at 10 and again at 13 weeks following plating of potatoes. Enzy...

Summary: | Boron (B)-treated and untreated Ontario potatoes were compared for enzymatic discoloration and phenolic and ascorbic acid concentration. The source of B was borax (Na2B4O7.10H2O) Which was sprayed on the leaves at the rate of 3.36 kg/ha at 10 and again at 13 weeks following plating of potatoes. Enzymatic discoloration was determined using the Hunter color difference meter. Ascorbic acid was determined using the indophenol method, and phenolic concentration was determined using Folin-Denis reagent. Discoloration of tubers was significantly decreased by boron application. The phenolic concentration was significantly decreased and the ascorbic acid concentration significantly increased by the application of boron foliar spray |
