The beneficial effects of using ascorbic acid with some micronutrients on yield and fruit quality of Hindy Bisinnara mango trees.

摘要

The effects of the individual or combined application of ascorbic acid (0, 25, 50, 100 and 200 ppm) and zinc, manganese and iron (0.0, 0.05, 0.10 and 0.20%) on grafted mango (cv. Hindy Bisinnara) were investigated in Qena, Egypt during 2000 and 2001. All treatments significantly improved the yield and fruit quality (in terms of fruit weight, pulp weight, total soluble solids, reducing and total sugars, total acidity and ascorbic acid content) of mango. The values of the evaluated parameters increased with the increase in the concentration of ascorbic acid and micronutrients applied.
