Production and Management Sabba, Robert P. [1], Drilias, Michael .J. [1], Bussan, A.J. [1]. Influence of the sprout-inhibitor maleic hydrazide on sugars and yield in potato . IT has been suggested that the sprout-inhibitor maleic hydrazide may increase the number of US #1 potatoes produced in field studies and lower the concentration of reducing sugars in storage, thus improving fry color. We tested the effect of maleic hydrazide at three different timings on total yield, US #1 yield, and glucose and sucrose concentrations of Atlantic and russeted tubers at harvest and out of cold storage. Maleic hydrazide had no effect on either total yield or US #1 yield for Atlantic regardless of the application timing. Although some maleic hydrazide applications actually increased either glucose or sucrose concentrations in Atlantic tubers at harvest, these differences did not affect either glucose or sucrose concentrations after three months cold storage. Maleic hydrazide increased sucrose concentrations, but did not alter glucose concentrations in Russet Burbank and Freedom Russet tubers after three months cold storage. Yield of Freedom Russet was unaffected by maleic hydrazide, but US #1 yield was actually decreased for Russet Burbank. In summary, maleic hydrazide did not lower glucose concentrations during storage and did not improve total or US #1 yield for Atlantic or russeted potatoes.
