Abstract
The research was carried out by the cultivation of sweet corn (Zea mays var. Saccharata) grains (Golden Sweet hybrid) at Al-Fakhurah village in Latakia governorate during the season 2018, according to the randomized complete block design (RCBD) with three replicates. The study aimed to determine the effect of plant spraying with hydrogen peroxide (H2O2) (10 and 20 mM), with amino acids (5 and 10 g/L), and with H2O2 and amino acids together in some growth, yield and quality characteristics of sweet corn hybrid plants. The spraying treatments with H2O2, especially at a concentration of 10 mM, and with amino acids, especially at a concentration of 10 g/L, alone or together, conducted to many positive effects on all growth (morphological and physiological traits), productivity (fresh ear yield) and quality (total protein and soluble sugar contents in fresh ear kernels) characteristics of golden sweet corn. Thus, these compounds spraying with concentrations (10-20 mM for H2O2 and 5-10 g/L for amino acids), alone or together, is recommended considering to their observed role in stimulating the growth of sweet corn plants (Golden Sweet hybrid), increasing fresh yield of ear and improving the protein and soluble sugar contents of kernels.
