Determination of endogenous zeatin/IAA levels in selected fortune mandarin mutants against Alternaria alternata pv. citri

Abstract

Alternaria brown spot is a serious disease in mandarins and mandarin hybrids. In this particular research, 9 Alterneria tolerant and 2 susceptible mutant individuals obtained from a series of in vitro and in vivo studies were used. Endogenous indole acetic acid (IAA) and zeatin hormone levels of the individuals were noted before and after the Alternaria disease inoculations in order to determine the hormonal variations during the research. It was determined that endogenous zeatin levels decreased after the inoculation compared to its initial levels. The indole acetic acid levels of the individuals increased after inoculation except for some individuals.
