Differences in wheat and triticale seed germination in the presence of natural and synthetic plant growth regulators

Abstract

A simple, fast and easy-to-perform method was carried out for the quantification of the effects of plant growth regulators on wheat and triticale. The method uses seed germination, root elongation and hypocotil growth in the plants as parameters in the presence of varying concentration of giberrellic acid (GA3), indol acetic acid (IAA), potassium nitrate (KNO3), magnesium sulfate (MgSO4) and AMO 1618. The highest germination rate was found in the seed treated with KNO3, 90% of wheat seeds germinated at concentration 10- 5M, while for triticale was 77.77% at a concentration of 10-4M. Longest roots were recorded in solutions of MgSO4, and the greatest impact on hypocotyl had GA3, for both wheat and triticale seeds. For both taxa retardant AMO 1618 was, at a concentration of 10-3M, led to complete inhibition of germination.
