EFFECT OF SEEDS SOAKING PLANTING IN THE GIBBERELLIN, POTASSIUM CHLORIDE AND ASCORBIC ACID IN THE GROWTH CHARACTERS AND HYDROCYANIC ACID CONTENT OF Sorghum bicolor (L) moench

Abstract

Pot experiment was carried out during autumn season in 2014. A Randomized Complete Block Design (R.C.B.D) was used in three replications to investigate the effect of seed soaking in distilled water, gibberellic acid concentration of 500,750 and 1000 mg liter-1, potassium chloride concentration of 10, 20 and 30 g liter-1 and Ascorbic acid concentration of 5,10, 20 and 40 mg liter1 as well as the comparison treatment (without soak), in growth characters and hydrocyanic acid content of sorghum a variety of HAYMAX Spanish in the following characteristics leaf area, plant height, Number of leaves, Stem diameter and content of leaf from hydrocyanic acid. The study showed the following results; Most studied characters showed significant difference with seed soaking results in most studied characters except Stem diameter, Number of leaves and Hydrocyanic acid in leaf which was not significant .Soaking treatment significant with gibberellic acid concentration of 500 mg liter-1 plant height 157cm concentration of 1000 mg liter-1 in leaf area 207.57 cm2 and significant Soaking treatment in gibberellic acid concentration 500 mg liter-1 and treatment ascorbic acid concentration 20 g liter-1 were superior in branches number about 3.33branch
