Abstract:

The objective was of the study were to examine different concentrations of hydrogen peroxide on some fruit quality parameters and yield of watermelon from individual grafted and ungrafted seedlings. The field trials were performed in four concentrations of hydrogen peroxide (H₂O₂+ C₂H₄O₂) and in combination of phosphorus pentoxide (P₂O₅ + K₂O) in 2010 and 2011, consequently. In the experiment 300 ml/100 L and 400 ml/ 100 L H₂O₂+C₂H₄O₂ alone, and combination with 60 ml/100 L and 80 ml/100 L P₂O₅ + K₂O were used in flowering, first fruit setting and when fruit size was 10-12 cm in diameter for both years. The results revealed that combination of H₂O₂+C₂H₄O₂ and P₂O₅+K₂O foliar applications improved yield significantly both per plant and total in grafted and ungrafted plants in the two years. Besides, such combinations also enriched total soluble solid content in grafted and ungrafted plants. However, those increases appeared more comparable in grafted ones. In addition, fruit thickness, titratable acidity (TA) and flesh colour (a*/b*) were considerably affected by all applications of hydrogen peroxide.
