The study aimed to investigate the effect of two plant growth regulators, namely ethephon (Eth) and methyl jasmonate (Ja-Me) at different concentrations and combinations (1% Eth; 1% Ja-Me; 5% Ja-Me; 1% Eth+1% Ja-Me; and 1% Eth+5% Ja-Me) on physicochemical properties of Acacia seyal var. seyal gums. The study covered two areas within the Sudanese “gum belt” (Shambat and Kenana), thus exemplifying the potentials and problems of gum Arabic production under clay soil in the dryland of Sudan. The results indicated that pedoclimatic conditions (locations) significantly affected gum characteristics; treatments, too, affected physicochemical properties of gum, but in an unpredictable way and with different intensities in the two study areas. Gums obtained by the application of growth regulators, complied with international laws and standards (European Council; Joint FAO/WHO Expert Committee on Food Additives; U.S. Food and Drug Administration; United States Pharmacopeia).

Abstract

The study aimed to investigate the effect of two plant growth regulators, namely ethephon (Eth) and methyl jasmonate (Ja-Me) at different concentrations and combinations (1% Eth; 1% Ja-Me; 5% Ja-Me; 1% Eth+1% Ja-Me; and 1% Eth+5% Ja-Me) on physicochemical properties of Acacia seyal var. seyal gums. The study covered two areas within the Sudanese “gum belt” (Shambat and Kenana), thus exemplifying the potentials and problems of gum Arabic production under clay soil in the dryland of Sudan. The results indicated that pedoclimatic conditions (locations) significantly affected gum characteristics; treatments, too, affected physicochemical properties of gum, but in an unpredictable way and with different intensities in the two study areas. Gums obtained by the application of growth regulators, complied with international laws and standards (European Council; Joint FAO/WHO Expert Committee on Food Additives; U.S. Food and Drug Administration; United States Pharmacopeia).
