Effect of various electrical voltages on the vegetative growth and the production of the active substances with medicinal properties in the Aloe vera

Abstract

An experiment was conducted in the lath house in the the Department of Horticulture . College of Agriculture,University of Baghdad. seedlings of Aloe vera plant were planted in plastic pots filled with sandy loam soil plants were treated with the following electrical voltage : E0, E1 = 50 volts, E2 = 75 volts, = E3 100 volts, treatment were repeated 4 times at weekly intervals .the electric power was 1/2 Ampere . The results showed that the different voltase treatment have no significant effect on vegetative growth.treatment with 50 volts increased the production of aloin and barbolin to 84.47 and 376.36 micrograms/ gm, respectively, compared with control produced 72.33 and 150.11 micrograms/ gm.Increasing the voltage to 75 volts increased the cinnamic acid, and Aloe emodin to 200.41 and 17.14 mcg respectively, compared with control 47.630 and 17.263 micrograms/ gm .Increasing electric voltage to 100 volts have no significant effect on the production of the active substances
