| Research Abstract |
This study aims to gain knowledge on tolerance/resistance mechanisms of sorghum and rice to Striga hermonthica. We clarified that differences in stomatal response to Abscisic acid (ABA) between sorghum and Striga induced water and solutes transfer from the host to the parasite. No evidence was found for ABA transfer from Striga to sorghum and this is not consistent with the hypothesis that tolerance to Striga relates to inactivation of ABA metabolism in host plants. Varietal differences in Striga resistance of host plants shown in rhizotron evaluations were confirmed in greenhouse and field experiments. Soil seedbank density and strain of Striga affected resistance of rice varieties, providing important information for the durability of Striga resistance.
