Study of the effect of potassium permanganate on the biochemical characteristics of onion (Allium cepa)

Plant hormones play important roles in plant growth and development. Ethylene is the only gaseous plant hormone that impact on plants is known about a century ago. Nowadays, ethylene absorbent like powdered potassium permanganate waterproof package for increasing the life after harvesting horticultural products are widely used, but there are no report on its application as spraying and soaking and the effects on plants. The aim of this study was to evaluate the effect of potassium permanganate on the biochemical characteristics of onion (Allium cepa). For this purpose, onion bulbs were treated by soaking or spraying directly on the foliage after germination, with different concentrations of potassium permanganate (0, 5, 10, 20, 40, 60, 80 and 100 ppm). Characteristics such as anthocyanins of leaves, chlorophyll, potassium, phenols, flavonoids of leaves, ethylene, fresh and dry weight were measured during the experiment. The use of potassium permanganate sprayed attract ethylene plant and a change in the physiological characteristics of the plant. So that the maximum amount of fresh weight (146.94 g) and potassium (66.497 g) recorded in 100 ppm spray treatment. The maximom amount of phenols (0.627) and phelavenoids (1.017) recorded in 5 ppm spray treatment and soaking control, respectively.
