The objective of this experiment was to study the effect of potassium peroxide as an oxygen generator on water consumption, yield and quality of a melon (Cucumis melo L) crop.
Urrestarazu and Mazuela (2005) indicated that the application of an oxygen supply based on potassium peroxide is effective on plants sensitive to hypoxia, such as pepper, and improves the hydric efficiency in case of melon.
Liberoxy[R] contains ~7% potassium peroxide. A dose of 1g x [1.sup.-1] was used according to the recommendations of Urrestarazu and Mazuela (2005).
With the NBT method, superoxide was generated by potassium peroxide. The inhibition rate was calculated by measuring the amount of the formazan which was reduced from NBT by superoxide.
